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.
