10.1.1 Parameter setting:
According to transducer, drag the motor’s rated nameplate data and conduct parameter setting for parameters
P0.07 and P0.08. The parameters that must be set up are stated as follows:
[P0.01]=0: parameter P0.01 is set up as 0; select the panel potentiometer setting frequency,
[P0.03]=0: parameter P0.03 is set up as 0; select panel to start and stop control.

10.1.3 Operating instructions
Press FWD to start the transducer; rotate the panel potentiometer button in clockwise, set up the frequency
gradually, rotate the panel potentiometer button in anticlockwise, set up frequency to reduce gradually, and press
STOP to close down the transducer.
Tips:
External control terminal FWD determines the operation direction of the motor; if FWD-COM is disconnected, the
motor is forward; if FWD-COM is closed, the motor is reverse.

10.3.3 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 is closed or disconnected simultaneously, the transducer will
close down. The setting frequency is confirmed by external voltage signals (VI).
Tips:

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).
