Change the frequency (60Hz) at the maximum current input (at 20mA, initial value)

<How to change the maximum frequency>
When you use the 4 to 20mA input and want to change the frequency at 20mA from 60Hz (initial value) to 50Hz,
Changing
example
set "50Hz" in Pr. 126.
1.
Turn
until "
2.
Press
to show the currently set value
"
" (60.00Hz).
3.
Turn
to change the set value to
"
" (50.00Hz).
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 20mA. (Refer to
operation 2 to 5 of the section 3.5.5)
REMARKS
The frequency meter (indicator) connected to across terminals FM-SD does not indicate just 50Hz ... Why?
The frequency meter can be adjusted using calibration parameter C0 FM terminal calibration. (
the Instruction Manual (applied)).
Use calibration parameter C5 to set frequency at 4mA 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 4-5 and adjust at any point without a voltage applied. (
method of calibration parameter C7).
When performing a high speed operation at 120Hz or more, setting of Pr. 18 High speed maximum frequency is necessary.
(
Refer to the chapter 4 of the Instruction Manual (applied) ).
