• How to calculate the set frequency when the override function is used:
Main speed setting frequency (Hz): Terminal 1 or 4 input, multi-speed setting
Compensation (%): Terminal 2 input
Set frequency (Hz) = Main speed setting frequency (Hz) ×
200
150
Pr.252

Pr.253
50
0
0V
Voltage across terminals 2 and 5
NOTE
• When Pr.868 ≠ "0", the override function does not operate.
• To use terminal 4, the AU signal needs to be turned ON.
• After changing the Pr.73 setting, check the setting of the voltage/current input selection switch. Incorrect setting may cause
a fault, failure, or malfunction. (Refer to

By the terminal 1 (main speed) and terminal 2 (auxiliary) input, the set
frequency is set as shown in the figure below.
