4.5. Troubleshooting

Symptom

Possible Cause and Solution

Stage will not move

Brake not released (if equipped with brake; refer to stage documentation).
In Limit condition. Check limits (refer to

Chapter 3: Electrical Installation

) 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: Electrical

Installation

 and Controller documentation).

Motor Connections (refer to

Chapter 3: Electrical Installation

and the Controller

documentation).

Stage oscillates or
squeals

Gains misadjusted (refer to the Controller documentation).
Encoder signals (refer to the Controller documentation).
