Drive reporting error E05. Defective motor Disconnect the flex cable and probe the Motor Power connector (white
Mate-N-Lok) in the open Junction Box.
1. Measure the resistance between pins 1 and 2, pins 2 and 3, and pins 1
and 3, and evaluate the measurements with the following criteria:
– The resistance values varies depending on the MPAS model, but
must be less than 15 Ohms.
– The difference between the three resistance measurements must
be less than 1 Ohm.
2. There must be an open circuit between pins 1, 2, 3, and pin 4 (GND).
If any measurement is not in range, return for factory service.
Cable carrier module exceeds its useful life of 10,000,000
cycles and is starting to fail. Replace cable carrier module. See Cable Carrier Assembly Removal on
page 62 and Cable Carrier Assembly Installation on page 62 .
Symptom Possible Cause Solution
Motor Power Connector Pin 1
Symptom Possible Cause Solution
Carriage is not moving but the controls
report axis motion. Rotary motor coupling broken or slipping. Remove rotary motor and verify integrity of coupling.
Excessive carriage play. Motor coupling set screw is loose. Tighten motor coupling set screw.
Ball screw end blocks have excessive wear. Return stage to factory for service.
Drive reporting error E05. Motor is damaged. Check that the phase-to-phase resistance of each motor phase. The
resistance must be equal, and not shorted to ground or to the shield.
Kinetix 6000 drive or Kinetix 2000 drive
reporting error E19.
Ultra3000 drive reporting error E19, E22, or
E23. Brake on the motor does not release. Manually release brake, and check that motor shaft is free to turn and the
bearing feels smooth.
