10.4 Multi-stage operation and external control mode   

10.4.1 Parameter setting:   

According to the transducer, drag the motor’s rated nameplate data and conduct parameter setting for 

parameters P0.07 and P0.08. [P0.03]1: Select external terminal command channel.   

[P3.26]- [P3.32]: 

Select multi-stage frequency setting.   

 

[P4.00]=1: 

External terminal X1 selects multi-stage control terminal 1.   

 

[P4.01]=2:

 External terminal X2 selects multi-stage control terminal 2.   

 

[P4.02]=3:

 External terminal X3 selects multi-stage control terminal 3.   

 

[P4.03]=11

: External terminal X4 selects external stop instruction.   

 

Basic wiring diagram

   

The basic wiring diagram of multi-stage operation and external control mode is shown in Figure 10-4(for 

reference only).

10.4.3 Operating instructions   

If FWD-COM is closed, the motor is forward (forward command); if REV-COM is closed, the motor is reverse 

(reverse command). If FWD-COM and REV-COM are closed or disconnected simultaneously, the transducer will 

close down. X1, X2 and X3 are disconnected with COM. Multi-stage operation is invalid. The transducer is 

operated according to the established command frequency (frequency setting channel is selected by parameter 

P0.01).   

If one or multiple terminals in X1, X2 and X3 is closed with COM terminal (seven combinations), the transducer 

is operated by the multi-stage frequency of X1, X2 and X3(multi-stage frequency setting value is confirmed by 

parameters P3.26-P3.32).
