4.5.5 Changing the output frequency (60Hz, initial value) at the maximum voltage
input (5V, initial value)
<How to change the maximum frequency>
The motor will not rotate ... Why?
Check that [EXT] is lit.
[EXT] is valid when Pr. 79 = "0" (initial value).
Use to lit [EXT].
Check that wiring is correct. Check once again.
Change the frequency (0Hz) of the minimum value of potentiometer (at 0V)
Adjust the frequency in calibration parameter C2 Terminal 2 frequency setting bias frequency. (Refer to
Chapter 4 of the Instruction Manual (Applied).)
When you want to compensate frequency setting, use terminal 1.
For details, refer to Chapter 4 of the Instruction Manual (Applied).
Changing example
When you use the 0 to 5VDC input to change frequency at 5V from 60Hz (initial value) to
50Hz, set "50Hz" in Pr. 125.
The monitor on the operation panel or the frequency meter (indicator) connected across terminals FM and SD does
not indicate exactly 50Hz.... Why?
The indicated value can be adjusted by the calibration parameter C4 Terminal 2 frequency setting gain
(Refer to Chapter 4 of the Instruction Manual (Applied).)
The frequency meter (indicator) connected across terminals FM and SD can be adjusted by the
calibration parameter C0 FM terminal calibration.
(Refer to Chapter 4 of the Instruction Manual (Applied).)
Set frequency at 0V using calibration
parameter C2.
(Refer to Chapter 4 of the Instruction
Manual (Applied).)
How can I operate at a frequency higher than
120Hz.
Additionally set Pr.18 High speed maximum
frequency.
(Refer to Chapter 4 of 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 2 and 5 and adjust at any point without a voltage applied.
(Refer to Chapter 4 of the Instruction Manual (Applied) .)

To check the setting, turn the start switch (STF or STR) ON
and input 5V (turn the potentiometer clockwise slowly to full.)
1.Turn until (Pr. 125) appears.
