Change The Frequency (60Hz) Of The Maximum Value Of Potentiometer (At 20Ma, Initial Value) - Mitsubishi Electric FR-A700 Instruction Manual

Make a start and stop with terminals
(external operation)
The motor will not rotate ... Why?
Check that [EXT] is lit.
[EXT] is valid when Pr. 79 = "0" (initial value) or "2".

Check that the AU signal is on.
Turn the AU signal on.
Check that wiring is orrect. Check it again.
Change the frequency (0Hz) of the minimum value of potentiometer (at 4mA, initial value)

<How to change the maximum frequency?>
Changing example When you want to use the 4 to 20mA input frequency setting potentiometer to change the 20mA-
time frequency from 60Hz (initial value) to 50Hz
Adjust to output 50Hz at 20mA current input.
Set "50Hz" in Pr. 126.

20mA current to flow.
The frequency meter (indicator) connected to across terminals FM-SD does not indicate just 50Hz ... Why?
The meter can be adjusted by calibration parameter C0 FM terminal calibration.
(Refer to section 4 of
Set frequency at 4mA using calibration
parameter C5 and adjust the indicator using
calibration parameter C0.
(Refer to section 4 of
(applied).)
REMARKS
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.
