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.

Condensation warning, indicates that the inverter (water)
temperature is lower than expected – possible causes
include inverter water valve stuck open.
Indicates that the inverter temperature is higher than
expected – possible causes include no or low cooling water
flow, inverter water valve stuck closed or water pipe to
inverter blocked.
Controller temperature above upper limit / Controller
temperature sensor open circuit - check water supply
Inverter heat-sink temperature above upper limit /
Inverter heat-sink temperature sensor open circuit - check
water supply
Motor temperature above upper limit / Motor temperature
sensor open circuit - check water supply
The loss of one of the three input phases has been
detected - check mains supply to drive or blown fuses
Upper controller temperature regulator active - current
limit reduced - check cooling
Upper heat sink temperature regulator active - current
limit reduced - check cooling
Reserved
Lower voltage regulator active - check mains voltage
Internal power supply fault - contact Edwards
Low controller temperature - contact Edwards
Low heatsink temperature - contact Edwards
Normally due to loss of can bus communication on dual
drive system, check usb lead is connected between master
and slave drives.
