5-55 Term. 33 Low Frequency
Range: Function:
100 Hz* [0 - 110000
Hz]
Enter the low frequency
corresponding to the low motor
shaft speed (that is low reference
value) in parameter 5-57 Term. 33
Low Ref./Feedb. Value.
5-56 Term. 33 High Frequency
Range: Function:
100 Hz* [0 - 110000
Hz]
Enter the high frequency
corresponding to the high motor
shaft speed (that is high reference
value) in parameter 5-58 Term. 33
High Ref./Feedb. Value.

High Ref./Feedb. Value.
5-59 Pulse Filter Time Constant #33
Range: Function:
100 ms* [5 - 1000 ms]
NOTICE
This parameter cannot be
adjusted while the motor is
running.
Enter the pulse lter time constant.
The low-pass lter reduces the
inuence and dampens oscillations
on the feedback signal from the
control.
This is an advantage if there is a lot
of noise in the system.
3.7.13 5-6* Pulse Outputs
Parameters for conguring the scaling and output
functions of pulse outputs. The pulse outputs are
designated to terminals 27 or 29. Select terminal 27 output
in parameter 5-01 Terminal 27 Mode and terminal 29 output
in parameter 5-02 Terminal 29 Mode.
