Figure 4-2 Simple Running Wiring Diagram
① Connect wires as per Figure 4-2;
② Switch on the power supply after confirming that the wires are connected
correctly, and the inverter will firstly display “P.oFF” and then “0”.
③ Confirm that the frequency setting channel is at the digit setting model ([F0.00]
= 0);
④ It is required to set parameter [F0.12] and [F0.13] according to the rated nameplate
data on the inverter’s dragging motor.
⑤ Press
RUN
STOP
key to start the inverter and the inverter will input 0 frequency,
displaying “0.0”.
⑥ Press Up of
key to increase set frequency, and the output frequency of the
inverter will increase and the motor revolution will also increase.
⑦ Check if the motor run normally. In case of any abnormity, stop running the motor
immediately and disconnect power supply. Do not run the motor until fault cause is
found.
⑧ Press Down on the
key to decrease set frequency.
⑨ Press
RUN
STOP
key again to stop running and cut off the power supply.
The default value of the carrier frequency is fixed (1.5-10 KHz). If the
motor is completely empty-load, slight oscillation may occur sometimes
in the operation under high carrier frequency. At this time, please reduce
the setting value of the carrier frequency. (Parameter [F0.08]).
