Basic Parameters 4-9

 Differential input, command pulse/direction (reference value of parameter 03: 0)
The command pulse indicates the rotation amount (CA, *CA), while the command sign (CB, *CB)
indicates the direction of rotation.
If (CB) is at the low level and (*CB) is at the high level, a forward direction command is issued.
 Open collector input, command pulse/direction (reference value of parameter 03: 10)
The command pulse indicates the rotation amount (CA, *CA), while the command sign (CB, *CB)
indicates the direction of rotation. If (CB) is at the low level and (*CB) is at the high level, a forward
direction command is issued.
 Differential input, forward/reverse pulse (reference value of parameter 03: 1)
The forward rotation pulse (CA, *CA) indicates the rotation amount in the forward direction, while
the reverse rotation pulse (CB, *CB) indicates that in the reverse direction.
