Value:
0 (OFF) - 100 Hz
Function:
Some systems call for some output frequencies to be avoided because of
mechanical resonance problems in the system. In parameters 230-231
Frequency bypass
these output frequencies can be programmed. In this
parameter a bandwidth can be defined on either side of these frequen-
cies.
Description of choice:
The frequency set in this parameter will be centered around parameters
