Step 13 – Testing The System

•The system can now be tested for performance. To do this, set the set-pointthrough the keypad and run the drive at some low level and check that the motor is operating properly and that the feedback signal level and polarity are correct.

•Check the system for dynamic operation and make any adjustments necessary for optimum performance. This may require making adjustments to parameters Bn-17 proportional gain and Bn-18 Integral Time. (Refer to Step 10)

NOTE: Parameters Bn-17 and Bn-18 may be changed through the keypad while the system is operating.

A word of CAUTION ! - the parameter changes should be made in small increments and the results checked to avoid highly unstable and possibly damaging conditions.

•This should complete the installation.
