10.2 Three-wire system control mode
10.2.1 Parameter setting
According to the transducer, drag the motor’s rated nameplate data and conduct parameter setting for
parameters P0.07 and P0.08.
[P0.01]=0:
Parameter P0.01 is set up as 0. Select the panel potentiometer to confirm the frequency input.
[P0.03]=1:
Parameter P0.03 is set up as 1; select the external terminal control.
[P4.17]=2:
parameter P4.17 is set up as 2; select AO1 output as the voltage output.
[P4.19]=0:
parameter P4.19 is set up as 0, select AO2 output as frequency output.
[P4.08]=3:
parameter P4.08 is set up as 3, select external command mode as the three-wire mode 1.
[P4.00]=9:
parameter P4.00 is set up as 17, select input terminal 1 as three-wire operation control.
Other parameters are set up in accordance with the specific circumstance.
