9.26 dV/dt filter plus Voltage Peak Limiter
NOTICE
Damage to the dv/dt filter by exceeding the maximum output frequency
The maximum permissible output frequency when using a dv/dt filter is 150 Hz. The dv/dt
filter can be damaged if the output frequency is exceeded.
• Operate the dv/dt filter with a maximum output frequency of 150 Hz.
NOTICE
Damage to the dv/dt filter by exceeding the maximum pulse frequency
The maximum permissible pulse frequency when using a dv/dt filter is 2.5 kHz or 4 kHz.
The dv/dt filter can be damaged if the pulse frequency is exceeded.
• When using the dv/dt filter, operate the Motor Module with a maximum pulse frequency
NOTICE
Damage to the dv/dt filter if it is not activated during commissioning
The dv/dt filter may be damaged if it is not activated during commissioning.
• Activate the dv/dt filter during commissioning using parameter p0230 = 2.
NOTICE
Damage to the dv/dt filter if a motor is not connected
dv/dt filters which are operated without a motor being connected can be damaged or
destroyed.
• Never operate a dv/dt filter connected to the Motor Module without a connected motor.
Note
Setting pulse frequencies
It is permissible to set pulse frequencies in the range between the rated pulse frequency and
the relevant maximum pulse frequency when a dv/dt filter plus Voltage Peak Limiter is
deployed. When doing so, take into account the "Current derating as a function of the pulse
frequency; refer to the Technical data.
