Performing Operations Using a 3-wire Sequence
By
selecting 0 for any parameter from H1-01 to H1-05 (related to terminals S3 to S7), the selected terminal
functions
as a forward/reverse run command, and terminals S1 and S3 change functions to 3-wire sequence
commands.
When
the Inverter is initialized for 3-wire sequence control (A1-03=3330), multi-function input 3 (terminal
S5)
will be the forward/reverse direction.

Use a sequence that turns ON terminal S1 for 50 ms or longer for the run command. This will make the run
command self-holding in the Inverter.
