Chapter 2 - Operation
22
Note: The user may also operate the inverter by setting the operation reference signal from the Keypad, and setting
the frequency reference signal to the control terminal. (Set DRV-03 (drv) to 0 (Keypad), and the DRV-04 (Frq) to 2
(V1)).
Note: FU1-20, FU1-21, FU1-25, FU1-36, FU2-54, FU2-83, I/O-05, I/O-10 are set at 50Hz for Standard (EU) types
and 60Hz for US types.
2.4 Operation
2.4.1 Operation From Keypad and Control Terminal
When the operation reference signal is given to the control terminal and the frequency setpoint is given
by the keypad, set the DRV-03 (drv) to 1 (Fx/Rx-1), and set the DRV-04 (Frq) to 0 (Keypad-1).
The frequency reference signal is set from the control terminal, and the forward, reverse, stop key of the
keypad is invalid.
1. Turn the power ON and set the operation and the frequency parameters.
2. Set the DRV-03 (drv) to 1 (Fx/Rx-1), and the DRV-04 (Frq) to 0 (Keypad-1).
3. Turn ON the operation reference signal FX (or RX). Keypad LED (FWD key or REV key) will turn ON.
4. Set the operating frequency with the keypad. Use the FUNC, ▲ (Up), FUNC keys and set the
frequency to 50.00Hz. The motor will rotate at 50Hz. The LED (RUN) of the keypad will blink when the
inverter is accelerating or decelerating.
5. Turn the operation reference signal FX (or RX) OFF. The LED (FWD of REV) of the keypad will turn
OFF.
2.4.2 Operation From Control Terminal
1. Turn the power ON and set the operation and the frequency reference to the control terminal mode.
2. Set the DRV-03 (drv) to 1 (Fx/Rx-1), and the DRV-04 (Frq) to 2 (V1).
3. Set the analog frequency reference by turning the potentiometer (frequency reference) slowly to the
right. The keypad will display the output frequency (50.00 Hz).
4. Slowly turning the potentiometer (frequency reference) to the left will decrease the output frequency.
The inverter will stop operating and the motor will come to a halt when the frequency reaches 0.00Hz.
5. Turn OFF the operation reference signal FX (or RX).
