1. When the A.W.OFF input is turned to “ON,” the driver cuts off the current supply to the
motor and the motor loses its holding-brake force.
In this condition the position of the output shaft can be adjusted manually.
2. When the A.W.OFF input is turned to “OFF,” the driver resumes the current supply to the
motor and restores the motor’s holding-torque.
The A.W.OFF input must be “OFF” when operating the motor.
Note
When the A.W.OFF input is not used, keep the A.W.OFF input in the “OFF” or leave it
disconnected.
C/S (step angle switching) input
This signal selects the step angle set with one of the two step-angle setting switches
(DATA1 and DATA2).
For example, when DATA1 is set to [0: 0.72°] and DATA2 is set to [6: 0.072°], this signal
can switch between 0.72°-step operation and 0.072°-step operation. For details on
setting the step-angle setting switch, see page 25, “Step angle.”
1. When the C/S input is turned to “ON,” operation switches to the setting for step-angle
setting switch DATA2.
2. When the C/S input is turned to “OFF,” operation switches to the setting for step-angle
setting switch DATA1.
A.W.OFF (All Windings Off) input
This is used to rotate the motor’s output shaft and adjust its position.
• Do not turn the A.W.OFF (All Windings Off) input to “ON” while the
motor is operating. The motor will stop and lose its holding ability,
which may result in injury or damage to the equipment.
Warning
• Before moving the motor directly with the hands (as in the case of manual
positioning), confirm that the driver A.W.OFF (All Windings Off) input is
“ON” to prevent injury.
