	What is the approximate maximum number of times the Sigma II Series flash ROM can be written? Posted Date: 02/14/2006 Answer: The flash ROM can be written to approximately 10,000 times. One should avoid frequent and unecessary writing to the flash ROM when possible. If frequent tuning is necessary, Yaskawa recommends using methods which minimize frequent overwriting of the flash ROM.

	What is the ambient temperature derating (L8-12 setting)? Posted Date: 01/22/2007 Answer: The output current capacity and the overload capabilities of the inverter depend on the ambient temperature. The higher the ambient temperature the lower is the maximum output current because the heat dissipation becomes more difficult. The overload protection function is active only when the current is above the maximum continuous output current level (112% of inverter rated current). At ambient temperatures higher than 45°C (40°C for IP20) this level will be lowered. The ambient temperature can be set in parameter L8-12. The setting range is 45°C to 60°C. Because the inverter has no IP00/20 detection the set value for L8-12 must be 5° higher than the real ambient temperature at IP20 units.

	What is the air gap requirement for Yaskawa's Linear Motors? Posted Date: 07/13/2004 Answer: The air gap between the Linear Motor Coil and the Magnet track is as follows: SGLGW40 & SGLGW60 Coreless Series: 0.8 mm +/- 0.3 mm SGLFW Iron Core Series: 0.8 mm +/- 0.3 mm SGLTW20 & SGLTW35 Iron Core Series: 0.8 mm +/- 0.3 mm SGLTW40 & SGLTW80 Iron Core Series: 1.2 mm +/- 0.3 mm. The air gap or the air gap tolerance is a fixed value and is solely the function of the mechanical structure i.e. bearings and frame (not a function of the attraction force between the magnet track and the motor coil). The attaction force will change if the air gap is more or less than that which is optimum.

	What is SPi fault displayed? Posted Date: 04/21/2014 Answer: This is an indication that there is an input phase loss or there is internal component damage. Check input power and if possible, monitor input phase voltage (both line-to-line and line-to-ground). A missing input phase or large input voltage imbalance will result in SPi fault generation. Repair or replace the inverter with new Yaskawa drive according to the application For more information, please see the technical manual TM.4505 or view the P5 GPD506 Drive product page.

	What is speed feedback compensation and when should it be used? Posted Date: 07/13/2004 Answer: Speed feedback compensation is typically applied when there is mechanical resonance in the system and the speed loop gain cannot be raised to achieve good response, such as shortened settling time in positioning. It allows the increase of speed reference gain with the speed feedback gain kept low by adjusting the speed feedback compensation value. Because the speed feedback gain is low, there is no vibration added to the resonance part of the machine, and good response is achieved due to the higher speed reference gain. The speed feedback compensation loop uses the speed feedback as the input. Using a proprietary algorithm, this signal is filtered to reduce the effect of disturbance and phase-lag compensation. The output is called the compensated feedback speed. This output, rather than the normal speed feedback signal may be selected via Pn110.1 for use in the speed control loop. Speed feedback compensation level, parameter Pn111, adjusts the gain of the speed compensation loop. Please note that with speed feedback compensation enabled, disturbance response is degraded because speed feedback gain is reduced. Also, the inertia ratio in Pn103 must be correctly set for the speed feedback compensation to function properly. Refer to section 6.2.6 in the Sigma II Servo System User's Manual for adjustment procedure.

	What is required to replace the digital operator on the V7 NEMA 4 drive? What is the replacement part number? Posted Date: 05/07/2015 Answer: Should the digital operator require replacement on a V7 NEMA 4 drive, it's recommended to replace both the cover and digital operator board (sold separately). This is because the operator overlay sheet is applied directly to the cover but the digital operator board is removable from the back of the cover. - The NEMA 4 cover part number for 0.2kW - 0.7kW drives is UUX000247. - The NEMA 4 cover part number for 1.5kW - 3.7kW drives is UUX000248. - The NEMA 4 digital operator board part number for 0.2kW - 3.7kW drives is CDR001106.

	What is an SSFDC Memory Card? Posted Date: 06/24/2013 Answer: SSFDC = Solid State Floppy Disk Card. More information regarding SmartMedia Technology can be obtained from the following web site: http://www.ssfdc.or.jp/english/spec/index.htm The EXOR Touch Screen series HMIs - eTOP10,11,12,30 currently ship with externally removable 8 Meg SSFDC SmartMedia cards already installed. 8 Meg is the largest memory capacity currently available with the current version of Designer for these HMIs (part #: MEM-08) - future development will allow increased memory capacity. The memory card stores the user program, and can be a medium for storing/transfering the Boot, Firmware, and MIPs code which operates the HMI. The advantage of memory card allows the user to easily maintain/upgrade the HMI program & firmware once the HMI has been installed in the field. Contents on SSFDC Card: Boot Code = 300k Firmware = 409k MIPS Code = 316k MIPs Service = 32k Protocol = typical 32k User Program = variable * = once the Boot, Firmware, MIPs Code, and MIPS Service are transfered to the HMI processor, they can be deleted from the SSFDC. This memory card can also be purchased from any general retail store which sells this common SmartMedia storage technology. See attached .JPG for further information.

	What is Analog Resistive Touch Screen Technology? Posted Date: 12/21/2011 Answer: Analog Resistive Touch Screens are transparent data input devices commonly used with Industrial HMIs (such as EXOR), to provide a user friendly method of human-computer interaction. These screens can be operated with the touch of a finger (with or without gloves) or a stylus. Touch pressure from a stylus or finger causes electrical contact between top and bottom circuits thus activating the programmed object (minimum object size is based upon programmed object size - typical 16x8 pixel). Analog Resistive touch screens differ from grids in that they are not restricted to a minimum activating stylus size. which means when an operator touches an object on the screen, swiping is not required to overcome grid voids. Durability testing has proven greater than 3 Million activations. The attached .JPG image is an example of the Analog Resistive Touch Screen cross section and construction.

	What is an A.F50 Alarm? Posted Date: 03/03/2015 Answer: A.F50 is a Servomotor disconnection alarm. Cause: The detected torque is 10% or less, but the commanded torque reference is 90% or more for 10ms. This alarm is not activated in cases of BB due to hardware issues. In those cases, an A.F6 or A.b3 is generated instead. Alarm Reset is available Corrective Actions: Check the servomotor power line wiring. Tighten the motor power connection. Replace the servo amplifier.

	What is an A.E7 alarm and how is it cleared? Posted Date: 07/13/2004 Answer: The A.E7 is an alarm from the Sigma2 (SGDH-xxyE) Servopack that is missing an option card such as an MP940 or NS300 If an amplifier previously had an option card attached, and it is missing at power up, this alarm will occur and persist until the following is performed. Using a Hand Operator or the Built in Operator on the Servopack, the proper procedure is as follows: 1) Execute an "Initialize Parameters to Factory Default" Operation :Fn005 (Section 7.2.9 in Sigma2 manual) 2) Execute an "Alarm History Trace Back Clear" Operation: Fn006 (Section 7.2.5 in Sigma2 manual) 3) Execute an "Option Unit Detection Reset" Operation: Fn014 (Section 7.2.13 in Sigma2 manual) Keywords: AE7, error Product Group/Line: Servo Products, SGDH Sigma II Topic/Sub Topic: Ask a Technical Question, Alarm, Troubleshooting Document Number: DZIK-5HV62J Published Date: 07/13/2004 Share \| Rate Rate this article :	07/13/2004
	What is an A.E5 alarm? Posted Date: 01/22/2002 Answer: An A.E5 (AE5) alarm is a Mechatrolink Synchronization Error between an MP920 or MP930 controller (using SVB modules) and an NS-100. Every mechatrolink communications cycle, the controller increments Watch Dog Timer data (WDT). If the expected data does not match with the data in the NS-100 module, then it is known that the transmission packet also did not get written to/from local register memory (hence the node did not get updated with new deterministic data). Since this is a deterministic control system and data must be transfered, this will flag an A.E5 alarm and it will display on the SGDH LED display. To reset this alarm, the controller must perform the alarm clear sequence TWICE.
