Monitor Rev
The revision level of the
monitor data structure shared
between the line and motor
side processors does not
match.
monitor data structure shared
between the line and motor
side processors does not

Software Problem
Re-load proper software into both processors
MS Size
The motor side power
converter has detected that
the power bridge and current
sensors, do not match.

Verify Overload Curve Parameters
Check both OVLD START LEVEL (A5) and
OVLD TIME OUT (A5) parameters.
OVLD TIME OUT (A5) parameters.
Excessive Field Weakening
Verify that FULL FLD AMPS (A5) and WAEK
FLD AMPS (A5) are set correctly so that motor
can produce rated torque

Excessive Current Draw
Decrease accel/decel rate
Verify elevator counterweights
Verify mechanical release of elevator brake
Motor Problem
Check for motor failure
Check for faulty motor wiring
