1
Behaviour in case of DC−bus
overvoltage
Function active:
Function switched−off:
TRIP "OUE" (Lecom no. 22) in case of
DC−bus overvoltage
Message "OU"
2
Threshold for message "DC−bus
undervoltage (LU)" (400 V
controllers only)
Function active:
Function switched−off:
Threshold = 400 V DC
Threshold = 285 V DC
4
Scaling for I
2
t monitoring
Function active:
Function switched−off:
Scaling to device utilisation (C0056)
Scaling to apparent current
(C0054)
8
Limitation to maximum frequency
(C0011)
Function active:
Function switched−off:
Limitation to maximum frequency
(C0011) inactive
Only use for applications with
parameter set changeover if the
parameter sets have different settings
for C0011!
Limitation to C0011 active
32
Behaviour of power−dependent
switching frequency reduction
Function active:
Function switched−off:
Switching frequency is reduced from
16 kHz to 8 kHz, after 8 kHz operation
for 1 s changeover to 4 kHz.
Switching frequency is
immediately reduced to 4 kHz.
64
Behaviour of the
temperature−dependent
switching frequency reduction
and the process controller output
Function active:
Function switched−off:
l
During operation at a switching
frequency of 16 kHz and if
C0144 = 0, temperature−dependent
switching frequency reduction to 4
kHz is not possible
l
During operation at a
switching frequency of 16 kHz,
reduction to 4 kHz is also
carried out if C0144 = 0
l
During operation with application
I/O, only the process controller
output is reset. The I component is
not reset.
l
During operation with
application I/O, the process
controller output and the I
component are reset.
128
Demagnetising time before the
DC injection brake is activated
Function active:
Function switched−off:
Up to a power of 2.2 kW = 1000 ms
From a power of 3 kW = 250 ms
Up to a power of 2.2 kW = 250 ms
From a power of 3 kW = 1000 ms
