Error Displays

Errors are serious abnormalities that cause loss of motor control. The Error
display alternates between a three-digit error code and a six-digit text message.
The error displays repeat until the problem is cleared.
Possible Cause(s)
Motor thermal switch trips due to:
• High motor ambient temperature, and/
or
• Excessive current
Motor wiring error
Incorrect motor selection
Action/Solution
Replace battery.
Note: Battery replacement may cause loss of
absolute position. Homing may be necessary.
After verifying motor has stopped, recycle control
power.
Verify scaling parameter corresponds to analog
signal range.
• Verify velocity loop tuning.
• Verify system sizing.
Verify current limits do not restrict current to less
than system capabilities.
Verify scaling parameter corresponds to analog
signal range.
• Verify position loop tuning.
• Verify system sizing.
• If operated in preset mode, verify presets are
assigned.
• If operated in a normal/override mode, verify the
override function is assigned.
Action/Solution
• Operate within (not above) the continuous torque
