7 Menu 5 “PMS Motor Setup”
The PMS motor setup menu defines the motor characteristics for the controller.
Parameters from 10 to 16 are calculated by the auto tuning algorithm or recalculation process.
If it is necessary to tune these parameters, please consult DMC first.
Mistakes in the motor setup tables can cause serious accidents and/or defective controllers and/or
defective motors.

M5-1 Proportional gain speed controller “Kp Spd”
In torque mode it determines how aggressively the speed controller limits the speed of the motor to the active speed
limit value. Larger values provide tighter control.
If Kp is set too high, oscillations could arise when the controller starts to limit speed.
If Kp is set too low, the top speed might result higher than speed limit (overshoot).
In speed mode it determines how quickly the speed controller attempts to match the demanded speed. Larger values
provide quicker control.
If Kp is set too high, oscillations may arise as the motor approaches demanded speed.
If Kp is set too low, the top speed might result higher than speed limit (overshoot) and the speed control might be very
slow.
M5-2 Integral gain speed controller “Ki Spd”
In torque mode it determines how quickly the speed steady state error is zeroed. In other words how quickly speed is
stabilized to the active speed limit value. Larger values provide faster speed limiting.
If Ki is set too high, oscillations could arise when the controller starts to limit speed.
If Ki is set too low, it may take a long time before speed is stabilized to the speed limit value.
In speed mode it determines how quickly the speed steady state error is zeroed. In other words how quickly speed is
stabilized to the speed demand value. Larger values provide faster speed stabilization.
If Ki is set too high, oscillations could arise when the controller starts to limit speed.
If Ki is set too low, it may take a long time before speed is stabilized to the speed limit value.
