6.2.4 Motor control
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 WorkBench v5 to perform the basic system
tests (see section 5.4).
A motor that is controlled by
the analog output runs as
soon as the controller is
switched on.
Adjust the Spindle output’s offset potentiometer to remove
any of fset voltage (see section 4.4.2).
Use a digital output from the NextMove ST to control the
enable input of the motor’s drive amplifier . This will allow the
amplifier to be disabled at startup.
Verify that the NextMove ST and drive are correctly
grounded to a common earth point.
Motor is under control, but
when moved to a position
and then back to the start it
does not return to the same
position.
The motor is not maintaining synchronization with the
NextMove ST drive output signals due to excessive
acceleration, speed or load demands on the motor.
Check that the acceleration, speed and load are within the
capabilities of the motor.
