Troubleshooting

Symptom

Possible Cause and Solution

Stage will not move

In Limit condition. Check limits (refer to

Chapter 3

) and refer to the Controller

documentation for polarity and compatibility requirements (Example: voltage
requirements).
Controller trap or fault (refer to the Controller documentation).

Stage moves uncontrollably

Encoder (sine and cosine) signal connections (refer to

Chapter 3

and

Controller documentation).
Motor Connections (refer to

Chapter 3

and the Controller documentation).
