Change the frequency (60Hz) at the maximum voltage input (5V initial value)

< How to change the maximum frequency>
Changing
When you use the 0 to 5VDC input and want to change the frequency at 5V from 60Hz (initial value) to 50Hz,
example
set "50Hz" in Pr. 125.
Operation
1.
Turn
until "
2.
Press
to show the present set value
"
" (60.00Hz).
3.
Turn
to change the set value to

4.
Press
to set.
5.
Mode/monitor check
Press
twice to choose the monitor/
frequency monitor.
6.
To check the setting, turn the start switch (STF
or STR) ON and input 5V (turn the
potentiometer clockwise slowly to full). (Refer
to operation 2 to 5 of the section 3.5.3)
REMARKS
To change the value to more than 120Hz, the maximum frequency must be set to more than 120Hz.
The frequency meter (indicator) connected across terminals FM-SD does not indicate exactly 50Hz ... Why?
The frequency meter can be adjusted using calibration parameter C0 FM terminal calibration. (
the Instruction Manual (applied)).
Use calibration parameter C2 to set frequency at 0V and
calibration parameter C0 to adjust the indicator.
(
Refer to the chapter 4 of the Instruction Manual (applied)).
As other adjustment methods of frequency setting voltage gain, there are methods to adjust with a voltage applied to across
terminals 2-5 and adjust at any point without a voltage applied. (
method of calibration parameter C4.)
Make a start and stop with terminals (external operation)
