ERROR CODES FROM MOTOR
This function includes a number of error warnings from the motor control
systemforfrequency-controlledmotors(EWD)
31 Temperature of MCU control circuits too high HEAT SINK TOO HOT
32 Motor thermal protection has tripped MOTOR TOO HOT
33 The motor has received a start command from the PCU without
receiving an interlock signal from the door lock. The MCU receiving
circuitry for the interlock signal is not faulty NO INTERLOCK
35 Short-circuitbetweenmotorwindingsortoearth. MOTORSHORTNING
36 Fault in MCU receiving circuitry for lock acknowledgement signal. INTERLOCK HARDWARE
37 DC voltage too low LOW DC VOLTAGE
38 DC voltage too high HIGH DC VOLTAGE
39 DC level varying too much RIPPEL ON DC BUS
40 One phase missing for/at motor control unit LINE INTERRUPT
41 Hardware fault, temperature monitoring, motor KLIXON CIRCUITS
42 The motor controller (MCU) (inverter) contains several different parameter sets
for different motors. During power up the timer checks that the correct
parameter set digit is written into the MCU. If not, the timer will write
down the parameter set digit defined in fixed config.
If the MCU discovers that no parameter set value is written down into
the MCU, the error coce will be displayed. NO PARAM. SET IN MCU
