By entering the sum of the selected values
you can activate a combination of the
functions.

Behaviour in case of overvoltage in the DC
bus

Function is active:

Function is switched off:

TRIP "OUE" (Lecom No. 22) in case of
overvoltage in the DC bus

Message "OU"

Threshold for message "Undervoltage in the
DC bus (LU)" (only for 400 V controllers)

Function is active:

Function is switched off:

Threshold = 400 VDC

Threshold = 285 VDC

Reference for I2t monitoring

Function is active:

Function is switched off:

Reference to controller load (C0056)

Reference to the apparent current (C0054)

Limitation to maximum frequency (C0011)

Function is active:

Function is switched off:

Limitation to maximum frequency (C0011) is
inactive
Only for applications with parameter set
changeover if C0011 is set differently in the
parameter sets.

Limitation to C0011 is active

Behaviour of the power−dependent chopper
frequency derating

Function is active:

Function is switched off:

Chopper frequency is reduced from 16 kHz to
8 kHz, and after one second of operation with
8 kHz it is switched to 4 kHz.

Chopper frequency is immediately reduced
to 4 kHz.

Behaviour of the temperature−dependent
chopper frequency derating and of the
process controller output

Function is active:

Function is switched off:

When operating with a chopper frequency of
16 kHz and C0144 = 0 no
temperature−dependent chopper frequency
derating to 4 kHz occurs

When operating with a chopper
frequency of 16 kHz it is also possible
with C0144 = 0 to derate it to 4 kHz

When operating with application I/O only the
process controller output is reset, but not the
integral component

When operating with application I/O the
process controller output and the
integral component are reset.

128

Demagnetising time before activating the
DC injection brake

Function is active:

Function is switched off:

Up to the power of 2.2 kW = 1000 ms
From a power of 3 kW = 250 ms

Up to the power of 2.2 kW = 250 ms
From a power of 3 kW = 1000 ms
