Operating at 60Hz or higher using the external potentiometer
< How to change the maximum frequency>
Changing
When you want to use 0 to 5VDC input frequency setting potentiometer to change the frequency at 5V from 60Hz (initial value)
example
to 70Hz, make adjustment to output "70Hz" at 5V voltage input. Set "70Hz" in Pr. 125.

Turn the start switch (STF or STR) ON.
[RUN] blinks fast because the frequency command is not given.
Acceleration  constant speed
Turn the potentiometer (frequency setting potentiometer) clockwise slowly to full.
5.
The frequency value on the display increases in Pr. 7 Acceleration time, and "
[RUN] indicator is lit during forward rotation operation and blinks slowly during reverse rotation operation.
Deceleration
Turn the potentiometer (frequency setting potentiometer) counterclockwise slowly to full.
6.
The frequency value on the display decreases in Pr. 8 Deceleration time, and the motor stops rotating with "
displayed. [RUN] blinks fast.
Stop
7.
Turn the start switch (STF or STR) OFF.
[RUN] turns OFF.
REMARKS
To change the value to 120Hz or more, the maximum frequency must be set to 120Hz or more.
Use calibration parameter C2 to set frequency at 0V and
calibration parameter C0 to adjust the meter.
(
Refer to Chapter 4 of the FR-E700 Instruction Manual
(Applied)).
 To input 10VDC to the terminal 2, set Pr. 73 Analog input
selection = "0". The initial value is "1 (0 to 5V input)".
(
Refer to Chapter 4 of the FR-E700 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 a method to adjust at any point without a voltage applied. (
Manual (Applied) for the setting method of calibration parameter C4.)
Change the frequency (60Hz) at the maximum current input (20mA in the initial setting)
Adjust it with Pr. 126 Terminal 4 frequency setting gain frequency. (
(Applied)).
Change the frequency (0Hz) at the minimum current input (4mA in the initial setting)
Adjust with the calibration parameter C5 Terminal 4 frequency setting bias frequency. (
Instruction Manual (Applied)).
