Question	Posted Date
In a vertical axis application, the motor trips the overtravel switch and coasts to the hard stop. What might be the cause? Posted Date: 07/23/2001 Answer: The SGDH servopack has the ability to control the stop mode when an overtravel is tripped (if overtravel switches are wired into the SGDH as recommended). The default method of stopping is to disable the motor and allow the dynamic brake to stop the motor. This method works very well in most horizontal applications, but vertical applications require a different method. When using an MP940, the SGDH overtravel function will disable the motor, even if the MP940 did not execute the disable servomotor block. In this mode, the motor will then continue to coast, and the MP940 is not able to apply torque to stop the motor (because it is not enabled). In this example, it is better to change the overtravel method to keep the motor enabled when an overtravel is tripped. This can be done by setting the overtravel stop mode Pn001.1 to 1 (default is 0). This change allows the MP940 to bring the motor to a controlled stop.

How long will a Sigma II absolute encoder remember its absolute position data without a battery attached? Posted Date: 07/13/2004 Answer: If the battery voltage drops below the minimum voltage of 2.7V, an A.83 alarm will occur on the SGDH amplifier to signal that battery replacement is necessary. The battery should be replaced as soon as possible. If the battery is removed (or the encoder cable is disconnected) while control power to the SGDH amplifier is off, the absolute encoder will lose its position data within 2 to 3 seconds. To prevent the encoder from losing its data, make sure you replace the battery while the SGDH amplier control power is on. After the battery has been replaced, the power to the amplifier should be cycled.

How is the % tolerance on the incoming voltage specs factored in for an SGDH? Posted Date: 06/25/2013 Answer: The percentages listed with the voltage rating are in addition to the voltage range listed. Specifications for the main circuit input terminals are listed in section 3.3.1 of the Sigma II user's manual (YEA-SIA-S800-32.2F). 30W to 200W -> Single-phase 100 to 115V (+10%, -15%) Applying the negative percentage on the low side yields a low voltage of 100V85%=85V and applying the positive percentage on the high side yields a high voltage of 115110%=126.5V The same methods apply to all of the voltage ranges listed for the main circuit power supply and control power supply.

How do I add external regenerative resistors? Posted Date: 12/14/2007 Answer: First, it is important to add a regenerative resistor with the proper resistance. Otherwise, damage to the ServoPack and/or poor performance may result. Please refer to the table in Section 5.6 of the Sigma II User's Manual [YEA-SIA-S800-32.2] for the minimum allowable resistance for each ServoPack model (see attachment below also). The user's manual also discusses calculating regenerative energy capacity. Once the amount of regenerative capacity has been determined, a resistor must be acquired to satisfy the requirements. Yaskawa offers a range of resistor pack units, and while they are designed and wired to work with particular sized ServoPacks, they can be rewired/reconfigured to work most any unit. Please reference the attached document for configuration and wiring details. Once a resistor has been acquired, it is connected between terminals B1 and B2 of the SGDH ServoPack. Be sure to remove the jumper between B2 and B3 (applicable to ServoPacks between 500W to 5.0kW). Now the external regenerative resistor's useable capacity must be calculated. There are two general variations to this: 1) Natural Convection Cooling. About 20% of convection cooled resistor's capacity may be used. For example, if a resistor has a nameplate value of 1000 watts, the maximum usable capacity is 1000Watts * 20% = 200 Watts (assuming natural convection cooling). This limitation is generally specified by the resistor manufacturer to insure high MTBF, so be sure to verify the capacity reduction in your specific operating environment. 2) Forced Air Cooling. About 50% of a forced air cooled resistors capacity may be used. For example, if a resistor has a nameplate value of 1000 watts, the maximum usable capacity is 1000Watts * 50% = 500 Watts (assuming forced air cooling). Lastly, the value for Parameter PN-600 (Regenerative Resistor Capacity) must be calculated and input. PN-600 is in units of 10W, so the above calculated valued must be divided by 10 and the result is input for PN-600. For the two examples above: PN-600 = (200/10) = 20, natural convection cooling PN-600 = (500/10) = 50, forced air cooling Attached Files: 99004a.pdf is external regen specifications for the Sigma II amplifier product. It outlines the minimum value resistor rating required for a particular model number and how to use/rewire the JUSP-RA04, 05, 18, 19 resistor packs to match that rating. Troubleshooting info Note: If an A.40 alarm (overvoltage) appears, it could be due to too much instantaneous power regeneration. A remedy could be to lower the resistance value of the shunt regen resistor (but be sure not to go below min rating). Note: If an A.32 alarm (Regeneration overload) appears, the RMS regen dissipating capacity must be increased. This alarm is governed through the Pn-600 setting) Attachments: 65KB Product Group/Line: Servo Products, SGDH Sigma II Topic/Sub Topic: Ask a Technical Question, Procedure - Policy, Start Up - Installation, Wiring Document Number: MNEN-5CJMRL Published Date: 12/14/2007 Share \| Rate Rate this article :	12/14/2007
How can an absolute encoder be used as an incremental? Posted Date: 09/21/2004 Answer: There are some situations where a user may wish to use an absolute encoder as an incremental encoder: - On some models, such as SGMAH and SGMPH, the absolute encoder has better resolution than incremental (16-bit vs. 13-bit), which can lead to better performance and tuning. - If an incremental encoder motor is unavailable, then an absolute encoder motor could be substituted without operational change. - Absolute encoder needs a battery when operating, but when it's used as incremental, the battery is not needed. To set the SGDH servopack to read an absolute encoder as incremental encoder, set Pn002.2=1 Product Group/Line: Servo Products, SGDH Sigma II, SGMAH Sigma II, SGMGH Sigma II, SGMPH Sigma II, SGMSH Sigma II Topic/Sub Topic: Ask a Technical Question, Operation, Options, Parameters Document Number: MTN-5YYLS5 Published Date: 09/21/2004 Share \| Rate Rate this article :	09/21/2004
How can a defective ServoPack (SGDH) be replaced in the field when a working MP940 is connected?

How are Yaskawa Servopacks (or Inverters) connected to a five wire 400VAC power source? Posted Date: 03/12/2002 Answer: Germany (and other European Countries) uses a five wire three phase 400VAC. Three wires are power, one is neutral, and one is ground. The 5 wire system is used to get balanced 400 V phase to phase and 230V phase to neutral (400/1.732) so control voltage can be obtained without a control transformer. In this case, the feeder transformer is a wye configuration, while the 5th wire is the power system ground. Some plants ground the neutral, while others float it. In the case of Yaskawa inverters and servos: For normal use, we ignore the neutral and utilize the 3 power phases and earth ground (system ground). For CE, Yaskawa's smaller inverters (V7, J7, and small servos) require the main AC power supply to be wye configuration with the neutral grounded in order to limit voltage to 277V or less to ground. This is to meet voltage clearance (LVD) requirements for CE.

How are the Electronic Gear Ratio parameters, Pn202 and Pn203, set for linear motors? Posted Date: 07/25/2005 Answer: The positioning resolution of the linear motor when used with the Sigma II SGDH servo amplifier in position mode is equal to the linear encoder scale pitch divided by 256. For a 20 micron pitch linear encoder (i.e. Renishaw RGH22B), the positioning resolution is 20 micron/256. The incoming position reference is scaled by the Electronic Gear Ratio. Pn202 is the Electronic Gear Ratio numerator, set to a default of 4. Pn203 is the Electronic Gear Ratio denominator, set to a default of "1". Therefore, with these these default settings, for every reference input pulse, the linear motor will move (4/1) x (20 microns/256) or 0.3125 microns, assuming a 20 micron pitch linear encoder. The Electronic Gear Ratio can be changed to allow for "friendlier" positioning units. For example, assuming a 20 micron pitch linear encoder: 1.) The desired position reference resolution is one micron (or 0.001mm). For every reference pulse, the linear motor moves one micron. To achieve this resolution, set Pn202=256 and Pn203=20. Now, for every reference pulse, the linear motor will move (256/20) x (20 microns/256) or one micron. 2.) The desired position reference resolution is 0.001 inch. Set Pn202=8128 and Pn203=25. Now for every reference pulse, the linear motor will move (8128/25) x (20 microns/256) x (25.4 inches/0.001mm), which is equal to 0.001 inch.

Do Sigma II motors comply with standard NEMA flanges for mounting? Posted Date: 07/25/2005 Answer: The SGMAH series of Sigma II servo motors include three models (200W, 400W & 800W) with standard NEMA flanges. For smaller motors in this series, (30W, 50W & 100W) a NEMA flange adapter (Yaskawa # SGM-N23) is available to provide standard NEMA mounting. Shaft diameters of standard Sigma motors differ from the NEMA standard. When selecting a NEMA model, the shaft size changes to SAE sizing. For the 200W and 400W motors, the shaft diameter is .50" (12.7mm), and for the 800W motor, the shaft diameter is .625" (15.875mm). The following are Yaskawa NEMA part numbers for reference.

Does Yaskawa sell the SGDM Sigma II amplifier in North America? Posted Date: 07/13/2004 Answer: The SGDM amplifier is a non-expandable Sigma II amplifier. It is sold only in Asia. However, the SGDH Sigma II amplifier is identical, except that the SGDH amplifier has a port on the side of the amplifier to interface with option cards such as the NS600 or MP940. If an imported machine (likely built in Asia) has an SGDM and needs a replacement amplifier, the SGDH can be used. It has exactly the same parameter set, runs exactly the same motors, and has exactly the same footprint. An expansion port protrudes 8mm from the side of the SGDH, but this is not a problem if the amplifiers were properly spaced (min. 10mm between amplifiers) in the cabinet. The part number for the SGDM amplifier follows this convention: SGDM-WWXYZ, where WW is the amplifier power rating (i.e. '04' for 400W or '55' for 5.5 kW), X is a letter determining input voltage (A= 200VAC, B=100VAC, D=400VAC), Y is the control code (usually 'D'), and Z is an optional revision level (usually either blank or 'A'). The replacement motor will be SGDH-wwxE, where ww is the same amplifier power rating and x is the same input voltage letter as the SGDM. For example, an SGDM-02BD would cross-reference to a SGDH-02BE and an SGDM-50ADA would cross to a SGDH-50AE.

Does Yaskawa offer Sigma II power and encoder cables rated for continuous flex? Posted Date: 06/24/2013 Answer: Yes. Many applications require cables that are more flexible than a standard cable. As a result, Yaskawa has introduced continuous flex rated cables for Sigma II motors up to 11kW (see attached document for complete cable specification summary for Sigma II). SGMAH and SGMPH motors feature continuous flex rated power and encoder cable assemblies as standard. For the larger SGMGH, SGMSH, and SGMUH motors typically installed in a static environment where physical movement of the motor is less likely, the standard cable remains a non-flex rated cable. Continuous flex rated cables are available for both power and encoder simply by specifying the 'CE' version of the cable [e.g., B1CE-03(A) instead of B1E-03(A)]. Continuous flex rated cable is manufactured to meet varying needs and requires proper application and installation to achieve the desired results. Testing methods vary by manufacturer, however, two key parameters are routinely published by cable manufacturers which can be used to calculate cable life (# of cycles) based on a design target of 10,000,000 cycles. They are: * Cable outside diameter (OD) * Minimum bending radius as a function of cable outside diameter (e.g., 10 X OD) If the minimum bend radius is too large, or a larger bend radius is acceptable, the effect on approximate cable life can be calculated as a function of the 10,000,000 cycle design target. The relationship between cable longevity and bending radius is non-linear. When calculating life cycle, the term "approximate maximum" is best suited to describe the resulting calculation. Use the following as a guideline for such calculations. 1) (Cable radius / Radius of Bend) x 100 = xx%. If xx% is less than 2%, the 10,000,000 cycle mark is approached. 2) Take the calculated xx% and calculate this ratio relative to the 2% design target. (2%) / (xx%) = Ratio of chosen bend radius relative to design target. 3) Multiply this ratio by 10,000,000 to calculate the approximate maximum number of cycles. Here is one example. Cable OD = 50mm. Minimum bending radius is 10 X OD. This means the minimum bend radius is 500 mm. This may be too large. Assume bend radius of only 400mm is possible. Thus, (25 mm / 400 mm) x 100% = 6.25%. (2%) / (6.25%) = 0.32 x 10,000,000 = 3,200,000 approximate cycles.

Can the Sigma II absolute encoder data be preserved when the encoder cable is removed? Posted Date: 02/11/2005 Answer: It is possible to back-up absolute encoder data by using a battery backup cable. The Sigma II absolute encoder does not have a high-storage capacitor like the Sigma I, so multi-turn position data will be lost within a few seconds once the encoder cable is disconnected. Normally, the encoder cable is not disconnected, and the data will be retained by the backup battery installed in the amplifier. In some cases, however, it may be necessary to disconnect the encoder cable. But the system must be able to backup the data in the absolute encoder. In these cases, it is recommended to use a battery backup cable. This battery backup cable is connected between the motor and the encoder cable. It has a battery built-in to the cable, so the encoder cable is no longer needed to bring the battery power from the amplifier. The attached document contains more information on how to construct such a cable.

Can the MP920 change the parameters in an SGDH amplifier? Posted Date: 08/19/2004 Answer: Yes, an MP920 with an SVB Module can read/write SGDH parameters via the register OLxx35. Depending on the motion command code, the OLxx35 register can hold three different types of data: 1. When Motion Command Code (OWxx20) is set to 17 (read servo parameter) or 18 (change servo parameter), OLxx35 contains the servo drive parameter number. Bits 0-11 are the Pn number and bits 12-15 are the number of words. When reading, the value of the servo parameter is stored in Pn Constant Read Data register ILxx28. When writing, the value stored in Pn Constant Change Data register, OWxx36, is written to the amplifier. 2. When Motion Command Code (OWxx20) is set to 19, OLxx35 contains the current servo drive alarm monitor number. The Alarm code is found in the Servo Drive Alarm Code Register, IWxx24. 3. When Motion Command Code (OWxx20) is set to 20, OLxx35 contains the current servo drive alarm history monitor number. When specifying a number between 0-9, the alarm code corresponding to the specified monitor number is stored in the Servo Drive Alarm Code Register, IWxx24. Example for reading Torque Reference Filter Time Constant, Pn401: 1. Set OWxx35 to H1401. The first three nibbles have the parameter number 401 and the last nibble specifies the number of words, in this case 1 (0~65535) 2. Change OWxx20 to 17. This will read the value of Pn401 and store it in the Pn Constant Read Data register, ILxx28. Example for writing Torque Reference Filter Time Constant, Pn401: 1. Set OWxx35 to H1401. The first three nibbles have the parameter number 401 and the last nibble specifies the number of words data, in this case 1 (0~65535) 2. Set the Pn Constant Change Data register, OWxx36, to the new value for the torque reference filter time constant, Pn401. 3. Change OWxx20 to 18. This will copy OWxx36 register value to Pn401.

Can the linear encoder be mounted "backwards" (positive direction of linear encoder opposite to positive direction of linear motor)? Posted Date: 04/28/2003 Answer: Yes, the linear encoder can be mounted "backwards" relative to the linear motor, it is good design practice to insure that the motor and encoder have the same positive direction reference. Normally, the linear motor and encoder would be oriented such that the positive direction of each is in the same direction. The positive direction of the linear motor is in the direction in which the motor cables/connectors protrude. Generally, this holds true for the linear encoder as well (as it does for Renishaw and Heidenhain). Please consult the linear encoder manufacturer in regards to positive orientation. If the linear encoder is mounted "backwards" relative to the linear motor, one of the following MUST be done in order for the linear motor system to function properly. 1. Rewire the linear encoder cable. Swap the "A" signal wires with the corresponding "B" signal wires. 2. The following is only applicable for Sigma II SGDH type servo amplifiers with the Y213 modification (Y213 modification is for use with linear motors only). Set user parameter Pn080.1=1 (B-phase progression). This will allow for proper commutation of the linear motor. However, the positive direction of the motor will now be in the direction opposite in which the motor cables/connectors protrude. To change the motor direction, set Pn000.0=1. 3. The following is only applicable for Legend SGDG type servo amplifiers. Set SW1 function selection switch no.4 (Linear Scale Polarity Reversal) to OFF (B-phase progression). This will allow for proper commutation of the linear motor. However, the positive direction of the motor will now be in the direction opposite in which the motor cables/connectors protrude. To change the motor direction, set SW1 function selection switch no.6 (Feedback Pulse B-phase Reversal) to OFF.
