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

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).
