3.7.13 5-6* Pulse Outputs
Parameters for configuring 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.

Function:
[0 - 110000 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.
Function:
[0 - 110000 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.
Function:
[-999999.999 Enter the low reference value [RPM]
for the motor shaft speed. This is
also the low feedback value, see
also parameter 5-52 Term. 29 Low
Ref./Feedb. Value.
Function:
[-999999.999 Enter the high reference value
[RPM] for the motor shaft speed.
See also parameter 5-53 Term. 29
High Ref./Feedb. Value.
Function:
NOTICE
[5 - 1000 ms]
This parameter cannot be
adjusted while the motor is
running.
Enter the pulse filter time constant.
The low-pass filter reduces the
influence and dampens oscillations
on the feedback signal from the
control.
This is an advantage if there is a lot
of noise in the system.
