Check the drive response
Now you can assess the drive performance with the aid of step
responses, which can be recorded using the digital scope function of the

.
Select the following four recording variables:
- 0:
Speed:Reference
- 1: Speed:Actual value
- 2: Torque:Reference
- 3: Torque:Actual value
Triggering condition:
Channel 0; rising flank, pre-trigger 10%; level: 30 min
-1
Start the drive with a reference value of e.g. 100 min
-1
.
Compare the step response of your drive with the illustration. With resolv-
ers the overshoot of the actual speed value should be around 20 %; with
sin/cos incremental encoders approx. 30% (with reference to the nominal
value). Make sure that the drive system shows small-signal response (the
nominal value of the torque must be less than the maximum value).
If the torque reference reaches its maximum, reduce the speed step.
The time response (rise time, correction time) of the speed control loop is
independent of the speed step.
