6-4 Troubleshooting
Check
Check that the NextMove ST is powered.
For serial connections, check that the serial cable is wired
correctly and properly connected. Check that no other
application on the PC is attempting to use the same serial
port.
For USB connections, check that the cable is properly
connected. Check that the USB device driver has been
installed.
Verify that WorkBench v5 is loaded and that NextMove ST is
the currently selected controller.
Check that the NextMove ST control card is correctly
connected to the baseboard.
Check
Check that the connections between motor and drive are
correct. Confirm that Relay0 has been configured as the
drive enable output (see section 5.3.2). Use WorkBench v5
to perform the basic system tests (see section 5.4).
Adjust the Spindle output's offset potentiometer to remove
any offset voltage (see section 4.4.2).
Use a digital output from the NextMove ST to control the
enable input of the motor's servo 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.
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.
Check
The system refresh has been disabled. Go to the Tools,
Options menu item, select the System tab and then
choose a System Refresh Rate (500ms is recommended).
