Performing Operations Using a Digital Operator
When b1-02 is set to 0, you can perform drive operations using the Digital Operator keys (RUN, STOP, JOG,
and FWD/REV). For details on the Digital Operator, refer to Chapter 3 Digital Operator and Modes .
Performing Operations Using Control Circuit Terminals
When b1-02 is set to 1, you can perform drive operations using the control circuit terminals.
Performing Operations Using a 2-wire Sequence
The factory setting is set to a 2-wire sequence. When control circuit terminal S1 is set to ON, forward operation will be performed, and when S1 is turned OFF, the drive will stop. In the same way, when control circuit terminal S2 is set to ON, reverse operation will be performed, and when S2 is turned OFF, the drive will stop.

Performing Operations Using a 3-wire Sequence
When any parameter from H1-01 to H1-10 (multi-function contact input terminals S3 to S12) is set to 0, terminals S1 and S2 are used for a 3-wire sequence, and the multi-function input terminal that has been set functions as a forward/reverse run command terminal.
When the drive is initialized for 3-wire sequence control with A1-03, multi-function input 3 becomes the input terminal for the forward/reverse run command.

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