Module Error Messages
Servo Restart Failed
Error ID: 2201, 2211
Servo Restart Failed: Pump channel A
B: Servo Restart Failed: Pump channel B
The pump motor in the module was unable to move into the correct position
for restarting.
When the module is switched on, the first step is to switch on the C phase of
the variable reluctance motor. The rotor should move to one of the C positions.
The C position is required for the servo to be able to take control of the phase
sequencing with the commutator. If the rotor is unable to move, or if the C
position cannot be reached, the error message is generated.
Probable cause Suggested actions
