6.2.3 Motor control
If the problem is not listed below please contact Baldor technical support.
Cannot communicate with the
controller after downloading
firmware.
After firmware download, always power cycle the controller
(remove 24 V power and then reconnect).
Symptom
Check
Controller appears to be
working but will not cause
motor to turn.
Check that the connections between motor and drive are
correct. Use Mint WorkBench to perform the basic system
tests (see sections 5.5 and 5.6).
Confirm that the drive enable output has been configured
(see section 5.4.3).
Ensure that while the NextMove ESB-2 is not in error the
drive is enabled and working. When the NextMove ESB-2
is first powered up the drive should be disabled if there is
no program running (there is often an LED on the front of
the drive to indicate status).
(
Servo outputs only
) Check that the servo loop gains are
setup correctly - check the Fine-tuning window. See
sections 5.6.2 to 5.9.
Motor runs uncontrollably
when controller is switched
on.
Verify that the NextMove ESB-2 and drive are correctly
grounded to a common ground.
(
Servo outputs only
) Check that the correct encoder
feedback signal is connected to the encoder input, the
encoder has power (if required, see sections 4.4.3 and
7.1.8) and is functioning correctly.
Check that the drive is connected correctly to the
NextMove ESB-2 and that with zero demand there is 0 V
at the drive's demand input. See section 5.6.1.
