Condition
Potential Cause
Possible Resolution
Auto-phasing is inaccurate
Check that hall sensors and encoder signal are
functional and not interfered by EMI in the system.
And redo auto-phasing.
Motor does not
respond to a
command
The axis is stopped by
FLS/RLS position limit sensor
or limited by software
position and velocity limits.
Check if FLS and RLS of the motor is active. Or it
could be a wrong setting where another sensor is
configured wrongly as the FLS or RLS of this motor.
Check software position limits and velocity limits at
Agito PCSuite’s CONFIG > POS page. If the FLS or RLS
signal is active when the digital input is changed, the
FLS or RLS status will remain ON. In this case, set the
digital input to FLS or RLS, manually move the motor
away from the sensor before change the digital
input function. Alternatively, reset the controller or
power cycle the controller.
The axis is configured in a
wrong operating mode or
function, e.g. as a slave axis
or another master.
Check all motion related configurations.
Motor connector is loose.
Check motor power connection.
The motor is faulty.
Measure motor’s resistance and inductance at
Agito PCSuite’s TUNE > CURR page to check if the
resistance and inductance values are close to the
motor specification.
If this is an actuator with
ballscrew, timing belt or
other transmission, the
coupling or other mechanical
part may be loose.
Check all mechanical transmission parts and
mechanism.
Motor brake is engaged
Check brake wiring and power supply.
