Fault Code
BIT
Combination
6 8 HIGHTC
4 HIGHTS
2 HIGHTM
1 MISSING_PHASE
7 8 UTCREG
4 UTSREG
2 UTMREG
1 LVREG
8 8 LOWVCC
4 LOWTC
2 LOWTS
1 LOWTM
Example:
PDT shows the following:
0108 0200
This translates to:
alarm 1 in bit 2 – PWM_TRIP
alarm 8 in bit 4 – OVERT
warning 2 in bit 6 - HIGHTM.
This means the motor overheated and switched the output off.
