12. Troubleshooting

In the event that your drive doesn't operate properly, the first step is to identify whether the problem is electrical or
mechanical in nature. The next step is to isolate the system component that is causing the problem. As part of this
process you may have to disconnect the individual components that make up your system and verify that they operate
independently. It is important to document each step in the troubleshooting process. You may need this documentation
to refer back to at a later date, and these details will greatly assist our Technical Support staff in deterMINIng the
problem should you need assistance.
Many of the problems that affect motion control systems can be traced to electrical noise, controller software errors, or
mistake in wiring.
Problem Symptoms and Possible Causes
Trouble
Motor is not rotating
Motor rotates in the wrong
direction
Red light blinking
Erratic motor motion
Motor stalls or loss steps
Excessive motor and drive
heating
No power, to start power supply
Pulse/revolution setting is wrong
DIP switch current setting is wrong
Fault condition exists or the drive is disabled
Motor phases may be connected in reverse
Maybe the pulse mode is CW&CCW, or the control signal is 24V without
connected 2K resistor.
Red light blinks 1 time or always on, try not to connect the motor and restart the
power supply
Red light blinks 2 times, check the power voltage and restart the power supply
Current setting is too small, losing steps
Wrong motor connection or has broken circuit in motor coil.
The current of the control signals is not in the range of 7-15mA
Control signals don't meet the requirements of
of the control signals
Output current of the drive is too small or motor torque is not enough
Acceleration is set too high
Power supply voltage too low
Modify the activated edge value in the ProTuner or the control signal is interfered
with.
Inadequate heat sinking / cooling
Automatic current reduction function not being utilized
Reduce output current
