Change The Frequency (60Hz) Of The Maximum Value Of Potentiometer (At 20Ma) - Mitsubishi Electric FR-F700 Series Instruction Manual

The motor will not rotate ... Why?
Check that [EXT] is lit.
[EXT] is valid when Pr. 79 = "0" (initial value).

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)
Adjust the frequency in calibration parameter C5 Terminal 4 frequency setting bias frequency.

Change the frequency (60Hz) of the maximum value of potentiometer (at 20mA)

<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.
1.
Turn until

Press to show the currently set value.
(60.00Hz)
3.
Turn to change the set value to "50.00".
(50.00Hz)
4.
Press to set the value.
5.
Mode/monitor check
Press twice to choose the
monitor/frequency monitor.
6.
Turn the start switch (STF or STR) on to allow
20mA current to flow.
(error at writing) is displayed.
The gain and bias frequency settings are too close.
Set frequency at 4mA using calibration
parameter C5 and adjust the indicator using
calibration parameter C0.
(Refer to the Instruction Manual (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.
(Refer to the Instruction Manual (applied) for the setting method of calibration parameter C7.)
