Damage to the dv/dt filter compact by exceeding the maximum pulse frequency
The maximum permissible pulse frequency when using a dv/dt filter compact is 2.5 kHz.
The dv/dt filter compact can be damaged if the pulse frequency is exceeded.
• When using the dv/dt filter compact, operate the Motor Module with a maximum pulse
frequency of 2.5 kHz.
Damage to the dv/dt filter compact if it is not activated during commissioning
The dv/dt filter compact may be damaged if it is not activated during commissioning.
• Activate the dv/dt filter compact during commissioning using parameter p0230 = 2.
Damage to the dv/dt filter compact if a motor is not connected
dv/dt filters compact which are operated without a motor being connected can be damaged
or destroyed.
• Never operate a dv/dt filter compact 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 f
requency when a dv/dt filter compact plus Voltage Peak Limiter
is deployed. "Current derating as a function of the pulse frequency" of the converter must be
observed here (refer to the Technical data).
During commissioning, the dv/dt filter compact plus Voltage Peak Limiter must be logged on
using STARTER or the AOP30 operator panel (p0230 = 2).
Note
Reset when establishing the factory setting
When the factory settings are restored, parameter p0230 is reset.
The parameter must be reset i
f the system is commissioned again.
