Basic Parameters
4
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.)

Rotation direction
selection 0: CCW rotation direction at forward command.
1: CW rotation direction at reverse command.
0 Power
This parameter keeps consistency between the direction of rotation of the servomotor and the traveling
direction of the machine.
In case of operation with pulse
The direction of rotation caused upon an input of a forward rotation pulse and high level command
sign or a B-phase pulse lead pulse with A / B phase pulse becomes the forward direction, making
the servomotor rotate forward.
To switch the phase of the output pulse, select the phase of counterclockwise (CCW) rotation of
the servomotor.
In case of operation with speed command data to the IQ area
VS type: When speed command data (4000H/3000 [r/min]) in word +12 in IQ area is set and the
FWD signal in word +14 is turned on the direction of rotation becomes the forward
direction, making the servomotor rotate forward.
LS type: When speed command data (in increments of 0.01 [r/min] with a sign) in word +10 in IQ
area is set and the FWD signal in word +15 is turned on the direction of rotation
becomes the forward direction, making the servomotor rotate forward.
