SGMAH Sigma II

SGMAH Sigma II -YAI

3,000 RPM to 5,000 RPM (Max Speed)

The SGMAH servomotor series is a legacy product and is no longer promoted in the Americas. It had a low-inertia design for extremely fast accelerations and short settling times. There were five frame sizes including NEMA 23 and NEMA 34 flanges providing up to 1,010 oz-in of peak torque.

What does the "-(A)" mean in the cable part number? Posted Date: 07/13/2004 Answer: The suffix on cable part numbers refers to the revision level of the cable. This means different things for different cables. For the SGMAH and SGMPH motor cables, this means more flexible cabling (compared to Sigma I). For SGMGH, SGMSH, and SGMUH, this means molded backshells for all power and encoder cables. In addition, 'CE' versions of these cables, feature continuous flex cable.

What are the vibration specifications for Sigma II Motors? Posted Date: 06/30/2008 Answer: The attached .JPG illustration is from Section 2.1.6 of the Sigma II users manual, and shows the vibration specifications measured in three axes at the flange of the motor. Note: Vibration in excess of this specification may cause an A.84 (A84) alarm. Note: When measured at the encoder, this may translate to up to 10G cantilevered force.

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	09/21/2004
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.

Are there any examples of servo sizing for rotary motors? Posted Date: 12/20/2001 Answer: Yes. Rotary motor applications can be sized using Yaskawa SigmaSize software. Yaskawa motors and amplifiers are recommended based on application requirements including load size, transmission type, vertical or horizintal orientation, and expected move profile. The attached files are sizing examples for various mechanical configurations such as: ballscrews, belt drive, rotary axis, sheet feeder nip roll, and straighteners.
