Basic Parameters

 Open collector input, forward/reverse pulse (reference value of parameter 03: 11)
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.
 Differential input, A/B phase pulse (reference value of parameter 03: 2)
The A-phase signal (CA, *CA) and B-phase signal (CB, *CB) indicate the direction of rotation and
rotation amount, respectively. Each edge of the A-phase and B-phase signals corresponds to one
pulse. (It is four-fold frequency in the amplifier.)
 Open collector input, A/B phase pulse (reference value of parameter 03: 12)
The A-phase signal (CA, *CA) and B-phase signal (CB, *CB) indicate the direction of rotation and
rotation amount, respectively. Each edge of the A-phase and B-phase signals corresponds to one
pulse. (It is four-fold frequency in the amplifier.)
