3.4.6 Changing the output frequency (60Hz, initial value) at the maximum current input
(at 20mA, initial value)
<How to change the maximum frequency?>
Changing example
When you use the 4 to 20mA input and want to change the frequency at 20mA from 60Hz (initial
value) to 50Hz, set "50Hz" in Pr. 126.
Selecting the parameter number
Turn until
1.
Press to show the present set value. (60.00Hz)
Changing the maximum frequency
Turn to change the set value to "
2.
Press to set the value. "
Mode/monitor check
3.
Press twice to choose the monitor/frequency monitor.
Start
4.
To check the setting, turn the start switch (STF or STR) ON and input 20mA. (Refer to 3.4.5 steps 2 and 3)
Set frequency at
parameter C5 and adjust the indicator using
calibration parameter C0.
(Refer to Chapter 4 of
(Applied).)
REMARKS
As other adjustment methods of frequency setting voltage gain, there are methods to adjust with a voltage applied across
terminals 4 and 5 or adjust at any point without a voltage applied.
