Troubleshooting 6-3MN1903
6.2.2 Communication
If the problem is not listed below please contact Baldor Technical Support. An oscilloscope will
be useful for many of the electrical tests described below.
Symptom
Check
Cannot detect NextMove
PCI
Check that the NextMove PCI driver has been installed.
Cannot communicate with
the controller.
Verify that WorkBench v5 is loaded and that NextMove PCI
is the currently selected controller. The MintMT operating
system (firmware) must be downloaded to the controller
each time it is powered.
Check the card is firmly seated in its socket in the computer
and this socket is of the correct type.
Check that the green S1 LED on the card backplate is
flashing (approximately twice per second).
6.2.3 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 or 5.8).
Ensure that while the controller is not in error the drive is
enabled and working. When the controller 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).
Check that the servo loop gains are setup correctly - check
the Fine-tuning window. See sections 5.4.2 to 5.6.
Motor runs uncontrollably
when controller is switched
on.
Check that the encoders are connected, they have power
through Encoder V+ (if required, see section 4.5.3) and are
functioning correctly. Use a dual trace oscilloscope to
display both channels of the encoder and/or the complement
signals simultaneously.
Check that the drive is connected correctly to the breakout
module and that with zero demand there is 0V at the drive
demand input. See section 5.4.1.
Verify that the breakout module and drive are correctly
grounded to a common earth point.
