32 OEM6250 Installation Guide Product Return Procedure Step 1 Obtain the serial number and the model number of the defective unit, and secure a purchase order number to cover repair costs in the event the unit is determined by the manufacturers to be out of warranty.
Appendix A T uning In this appendix: • Servo control terminology • Servo control techniques • Servo tuning procedures (These procedures are based on empirical techniques. If you are using Servo Tuner™, refer to the Servo Tuner User Guide for instructions.
34 OEM6250 Installation Guide Servo System Terminology This section gives you an overall understanding of the principles and the terminology used in tuning your OEM6250. Servo Tuning Terminology The OEM6250 uses a digital control algorithm to control and maintain the position and velocity.
Appendix A – Tuning 35 error, use the TPER (Transfer Position Error) command; the response represents the position error at the instant the command is received. When the motor is not moving, the position error at that time is called the steady-state position error (see definition of steady-state under Servo Response Terminology ).
36 OEM6250 Installation Guide Tuning-Related Commands More detailed information on each 6000 Series command can be found in the 6000 Series Software Reference . Tuning Gains : SGP .............. Sets the proportional gain in the P IV&F servo algorithm.
Appendix A – Tuning 37 Integral Feedback Control ( SGI ) Using integral feedback control , the value of the control signal is integrated at a rate proportional to the feedback device position error. The rate of integration is set by the Servo Gain Integral ( SGI ) command.
38 OEM6250 Installation Guide gain is needed for adequate damping, you can balance the tracking error by applying velocity feedforward control (increasing the SGVF value—discussed below).
Appendix A – Tuning 39 Tuning Setup Procedure Use the following procedure to set up your servo system before completing the tuning procedures. You can perform this procedure for both axes simultaneously.
40 OEM6250 Installation Guide d . Use the TFB command again to observe the feedback device’s position. The value should have increased from the value observed in Step 7.
Appendix A – Tuning 41 Actual Velocity Command Velocity VELOCITY TIME Step 3 Proceed to the Controller Tuning Procedure section to tune the OEM6250. Controller Tuning Procedure The Controller Tuning Procedure leads you through the following steps: 1 .
42 OEM6250 Installation Guide Step 4 Optimize the Proportional ( SGP ) and Velocity ( SGV ) gains ( see illustration on next page for tuning process ). a. Enter the following commands to create a step input profile (use a comma in the first data field when tuning axis 2—e.
Appendix A – Tuning 43 Tuning Process Flow Diagram (using proportional and velocity gains) OR Increase SGP UNTIL OR Decrease SGV UNTIL Increase SGV UNTIL OR OR Decrease SGV UNTIL OR Decrease SGP UNTIL OR Decrease SGV UNTIL Increase SGV UNTIL START STOP Step 6 Use the Velocity Feedforward Gain ( SGVF ) to reduce position error at constant speed .
44 OEM6250 Installation Guide Tuning Scenario This example shows how to obtain the highest possible proportional feedback ( SGP ) and velocity feedback ( SGV ) gains experimentally by using the flow diagram illustrated earlier in Step 4 of the Tuning Procedure .
Appendix A – Tuning 45 Step 8 After raising the SGV gain to 2.4, overshoot is reduced a little, but chattering reappears. This means the gains are still too high. Next, we should lower the SGV gain until chattering stops. SGP = 85 SGV = 2.4 Step 9 After lowering the SGV gain to 2.

Appendix B E M C I nsta lla tion G uide line s General Product Philosophy The OEM6250 was not designed originally for EMC compliance. Therefore, it will require specific measures to be taken during installation. The ultimate responsibility for ensuring that the EMC requirements are met rests with the systems builder.
