Start-Up Programming & Operation

■ Run the Drive using Digital Input Terminals: b1-02 = 1
This setting uses the digital input terminals to enter the run command. The factory
setting is a 2-wire sequence. The configuration in Figure 4.15 applies when a
setting of H1-0X= 0 is not used for any of the digital input terminals (H1-0X not
equal to 0).

Using a 3-Wire Sequence
When 3-Wire sequence is assigned to one of the digital inputs (H1-xx = 0), the
functions of the inputs S1 and S2 are set to 3-Wire sequence. The sequence works
as shown in Figure 4.16.

Note: When terminal S5 is open, the motor rotates forward. When closed, the motor
rotates in reverse.
