310 Unidrive SP Advanced User Guide
www.controltechniques.com Issue Number: 7
A sliding window filter may be applied to the feedback. This is particularly useful in applications where the feedback is used to give speed feedback
for the speed controller and where the load includes a high inertia, and so the speed controller gains are very high. Under these conditions, without a
filter on the feedback, it is possible for the speed loop output to change constantly from one current limit to the other and lock the integral term of the
speed controller.
Only read when Pr x.29 Action request is set high.
Host mode:
0 - Idle: No tuning or set-up
1 - Parameters are valid or will be set externally
• SERVO - Flux angle and all other parameter known - run only the current gains calculation.
• CLOSED LOOP - All parameters known - run only the current gains calculation.
2 - Pulse test tuning
• SERVO - Only flux angle known - run the pulse test to tune the current controller.
• CLOSED LOOP - Only field controller parameters known - run the pulse test to tune the current controller.
3 - Full tuning
• SERVO - run the minimal movement test to find the flux angle and then run the pulse test to tune the current controller.
• CLOSED LOOP - run the movement test (2/3 base speed) to tune the field controller and then run the pulse test to tune the current controller.
4 - RESET the whole initialisation system including trigger SLM command 245 and 246.
4 will hold the sequencer in reset.
Encoder only mode:
0 - Idle: No tuning or set-up
1 - Read information from the SLM EEPROM (CT Coder) and update the UniSP parameters
The parameter set to use is determined by the value of Parameters transferred (Pr x.28).
2 - Idle - no tuning or set-up
3 - Idle - no tuning or set-up
4 - RESET the whole initialisation system
4 will hold the sequencer in reset.
