Trigger condition:
Channel 0; rising edge, pretrigger 10%; level: 30 rpm
Start the drive with a reference value of 100 rpm for example.
Compare the step response of your drive with the diagram. With resolvers
the overshoot of the actual speed should be around 20 %; with sin/cos
incremental encoders around 30 % (referred to the reference value).
Make sure the drive system exhibits small signal response (the torque
reference value must be less than the maximum).
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.
