7. Application Examples
7.1 Panel control: start and stop, panel potentiometer set frequency
7.1.1 Parameter settings
According to the motor rated nameplate data, set the parameter A-5, A-6 for setting. Must set parameters as
following:
[A-1] = 0: parameter A-1 set to 0, choose panel potentiometer for frequency set.
[A-3] = 0: parameter A-3 set to 0, choose panel up, stop control.
7.1.2 Basic wiring diagram
Panel control start, stop, the basic wiring diagram of panel potentiometer set frequency as shown in
diagram 7-1 shows (for reference only).
Diagram 7-1: Panel control: start and stop, panel potentiometer set frequency wiring
7.1.3 Running description
Press "FWD" key for Start frequency inverter, clockwise swirl panel potentiometer knob, set frequency will
gradually increase. Counter clockwise swirl panel potentiometer knob, set frequency will gradually
decrease. Press "STOP", the frequency inverter will stop.
Remark
●
The external terminal FW decide the motor running direction. FWD-COM disconnection means the
motor is turning. FWD-COM connect mean the Motor reversal.
7.2 Three wire control mode
7.2.1 Parameter settings
According to the motor rated nameplate data, the parameter A-5, A-6 for parameter setting.
[A-0] = 1: Parameter A-0 set to 1, select the intermediate running parameters.
[A-1] = 0: Parameter A-1 set to 0, choose panel potentiometer to determine the frequency input.
[A-3] = 1: Parameter A-3 set to 1, choose external control.
[A-10] = 2: Parameter A-10 set to 2, choose AO output for voltage output.
[A-11] = 0: Parameter A-11 set to 0, choose FM output for frequency output.
[b-33] = 2: Parameter b-33 set to 2, choose external running instruction mode for three line mode.
[b-63] = 17: Parameter b-63 set to 17, select input terminal 1 for three line type running control.
Other parameters set please according to particular case.
