3.5.4 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 want to use the 0 to 5VDC input frequency setting potentiometer to change the frequency at 5V from 60Hz (initial
value) to 50Hz, make adjustment to output "50Hz" at 5V voltage input. Set "50Hz" in Pr. 125.
Operation Display
1.
Turn until " " (Pr. 125) appears.
2. Press to show the present set value
" " (60.00Hz).
3. Turn to change the set value to
" "(50.00Hz).
4. Press to set.
Flicker...50Hz output at 5V input complete!!
5. 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 operation 2 to 5 of the section 3.5.3)
REMARKS
To change the value to 120Hz or more, the maximum frequency must be set to 120Hz or more.
The frequency meter (indicator) connected across terminals FM-SD does not indicate exactly 50Hz ... Why?
The frequency meter can be adjusted using calibration parameter C0 FM terminal calibration. ( Refer to Chapter 4 of the
Instruction Manual (Applied)).
Use calibration parameter C2 to set frequency at 0V and
calibration parameter C0 to adjust the indicator.
(
Refer to Chapter 4 of the 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 adjust at any point without a voltage applied. ( Refer to the Instruction Manual (Applied) for the setting
method of calibration parameter C4.)
