4.4. Without pre-load, verify that the machine moves and that
each motor provides its corresponding torque according to
parameter "TORQDIST" (e.g. for a 50% distribution, half the
torque).
4.5. Monitor the torque of each motor (Sercos variable TV2).
When stalled, increase the pre-load gradually until the
motors provide torque in the opposite direction.
4.6. Slowly move in both directions and check that it works
properly. Make sure that it is not jerky and that each motor
provides its corresponding torque according to parameters
"TORQUEDIST" AND "PRELOAD".
4.7. Readjust the velocity loop on both motors with the method
normally used.
While changing the parameters of the velocity loop, it would be best
to change them on both drives at the same time. Since this is not
possible, we recommend to make small changes on the values or
change them while the motor is stopped.
