4.3.6 Changing the frequency (60 Hz, initial value) at the
maximum current input (at 20 mA, initial value)
• Change the maximum frequency.
With a 4 to 20 mA input frequency setting potentiometer, change the frequency at 20 mA from 60 Hz (initial value) to 50 Hz.
Adjust the setting so that the inverter outputs 50 Hz when 20 mA is input. Set "50 Hz" in Pr.126.
1. Changing the maximum frequency
Set "50.00 Hz" in Pr.126.
2. Checking the mode/monitor
Press to change to the monitor / frequency monitor.
3. Start
Turn ON the start switch (STF or STR) to input a 20 mA current. (Refer to steps 3 and 4 in 4.3.5.)
Operate at 50 Hz.
NOTE
• To set the frequency at 4 mA, use the Pr.904.
• Other adjustment methods for the frequency setting current gain are the following: adjustment by applying a current
through terminals 4 and 5, and adjustment using a specified point without applying a current through terminals 4 and 5.
