Optimization steps
You should not optimize any settings unless the load is connected (axis
mechanics).
Turn the power supply of the drive on. Enable the drive. The torque is active
at the drive.
Specify a constant position for the optimization time.
Change the loop gain factor (S-0-0104) with the DSS to the value ”0”.
This is to ensure that the subsequent settings are not influenced by position
control.
Use the DSS monitor and the ”block diagram” (cf. page 4–17), if necessary,
for entering and testing parameters.
Start with the default value of S-0-0100 (approx. ”50”).
You may use the following sequence chart for optimizing the speed control:
