Result:
If the step response of your drive more or less matches the diagram, you
can be sure that the motor phases are correctly wired, the encoder is
correctly connected, and the CDD3000-HF parameters are set to the
correct motor.
If the step response deviates severely from the diagram, it is to be
assumed that
•
the motor data set was selected incorrectly, or
•
the cabling is faulty
Check the individual steps from Section 3 "Installation" and Section 4.3
"Initial commissioning" and repeat the test run.
The step response may also deviate if the ratio of the machine moment of
inertia reduced onto the motor shaft relative to the motor moment of
inertia is very high. Here the loop control settings must be optimized. For
special settings to optimize the speed and position control loops, please
use the CDD3000 Application Manual.
