4.1 Pulse Output Mode
4.1.1 Selection of Rotation Direction
Changing this settings allows to rotating a motor in a reverse direction under the same connection status
and the driver settings.
Shared momory Control code Higher the 8th. bit 0= forward rotation
1= reverse rotation
4.1.2 Selection of Pulse Output Mode
The pulse output mode can be selected to match the pulse input mode supported by the motor driver.
The two types of pulse output described below can be selected.
Shared memory Control code Higher the 9th. bit 0: Pulse / Sign
1: CW/CCW
Pulse/sign output method
With this method, pulse output signals for motor drive (signals that determine the rotation speed of the
motor) and signals that determine the rotation direction of the motor are output.
Pulse signals (pulses) are output from the pulse output A pin, while signals that determine the rotation
direction (signs) are output from the pulse output B pin.
CW/CCW output method
With this method, pulse output signals for forward rotation and pulse output signals for reverse rotation
are output in response to the direction in which the motor is rotating (CW/CCW: clockwise/counter -
clockwise).
When the shared memory control code Higher 8 bit is 0 (default setting), forward rotation (CW:
clockwise) pulse signals are output from the pulse output A pin, and reverse rotation (CCW: counter -
clockwise) pulse signals are output from the pulse output B pin.
