IGBT temperature
IGBT Inverter Bridge overtemperature
protection has detected too high a short
term overload current
Check loading.
Check motor size.
42
Brake resistor
overtemperature N/A
Brake resistor overtemperature
protection has detected too heavy
braking
Set the deceleration time longer.
Use external brake resistor.
43
Encoder fault
Note the exceptional Fault data record.
See 7.3.4.3. Additional codes:
1 = Encoder 1 channel A is missing
2 = Encoder 1 channel B is missing
3 = Both encoder 1 channels are
missing
4 = Encoder reversed
Check encoder channel connections.
Check the encoder board.

Analogue input I
in
< 4mA (sel. signal
range 4 to 20 mA)
Current at the analogue input is < 4mA.
control cable is broken or loose
signal source has failed
Check the current loop circuitry.
51
External fault
Digital input fault.
52
Keypad communi-
cation fault
There is no connection between the
control keypad and the inverter.
Check keypad connection and possible
keypad cable.
