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).
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
Instruction Manual (applied).)
When you want to compensate frequency setting, use terminal 1.
For details, refer to
3.5.4
Change the frequency (50Hz) of the maximum value of potentiometer (at 5V)
<How to change the maximum frequency?>
Changing example
When you want to use the 0 to 5VDC input frequency setting potentiometer to change the 5V-
time frequency from 50Hz (initial value) to 40Hz
Adjust to output 40Hz at 5V voltage input.
Set "40Hz" in Pr. 125.

Mode/monitor check
Press
twice to choose the monitor/frequency monitor.
6.
Turn the start switch (STF or STR) on and turn the volume
(frequency setting potentiometer) clockwise to full slowly.
(Refer to 3.5.3 steps 2 to 5)
Set
frequency
at
parameter C2 and adjust the indicator using
calibration parameter C0.
(Refer to
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 2-5 and adjust at any point without a voltage applied.
