Changing The Output Frequency (60Hz, Initial Value) At The Maximum Voltage Input (5V, Initial Value) - Mitsubishi Electric F700 Instruction Manual

Start and stop using terminals (External
operation)
REMARKS
Pr. 178 STF terminal function selection must be set to "60" (or Pr. 179 STR terminal function selection must be set to "61").
(all are initial values)
The motor will not rotate ... Why?
Check that [EXT] is lit.
[EXT] is valid when Pr. 79 = "0" (initial value).
Use
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 the
chapter 4 of
When you want to compensate frequency setting, use terminal 1.
For details, refer to the chapter 4 of
3.6.4 Changing the output frequency (60Hz, initial value) at the maximum voltage
input (5V, initial value)
<How to change the maximum frequency>
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.

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 5V (turn the potentiometer clockwise slowly to full.)
(Refer to 3.6.3 steps 2 to 5)
The frequency meter (indicator) connected across terminals FM-SD does not indicate exactly 50Hz ... Why?
The meter can be adjusted by calibration parameter C0 FM terminal calibration. (Refer to the chapter 4
of the Instruction Manual (applied).)
Set frequency at
parameter C2 and adjust the indicator using
calibration parameter C0.
(Refer to the chapter 4 of
Manual (applied).)
REMARKS
As other adjustment methods of frequency setting voltage gain, there are methods to adjust with a voltage applied to across
terminals 2-5 and adjust at any point without a voltage applied.
