Command pulse / sign (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.
Differential input
・
Open collector 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.
