7.2.3 Operating instructions
FWD, X1, COM closed, the motor forward run (forward command); REV, X1, COM closed, the motor
reverse run(reverse command). FWD, X1, COM together open or one terminal open ,or at this time let
REV closed, frequency inverter stop. REV, X1, COM and at the same time open, or one of the terminal
open, or will the FWD closed, frequency inverter stop.
7.3 External control mode, external voltage setting frequency
7.3.1 Parameter settings
According to the motor rated nameplate data, the parameter A-5, A-6 for parameter setting.
Must set parameters are as following:
[A-1] 2: Parameter A-1 set to 2, choose external voltage 1 (V1) can accept 0~10V signal for frequency
setting.
[A-3] = 1: Parameter A-3 set to 1, choose external control.
7.3.2 The basic wiring
As diagram 7-3, the wiring of external control, external voltage is setting frequency.
