Control Input Details
DIO CN1-1
CCWL CCW limit
Pin No. 1 is the plus (+) direction limit input signal. When this signal is not being input (ON), the motor
cannot be rotated in the plus (+) direction.
If this signal turns OFF during motor rotation in the plus (+) direction, the motor will be stopped accord-
ing to the PP-25 (alarm selection) setting.
DIO CN1-2
CWL CW limit
Pin No. 2 is the minus (–) direction limit input signal. When this signal is not being input (ON), the motor
cannot be rotated in the minus (–) direction.
If this signal turns OFF during motor rotation in the minus (–) direction, the motor will be stopped ac-
cording to the PP-25 (alarm selection) setting.
DIO CN1-3
ORG Origin proximity
Pin No. 3 is the input for determining the mechanical origin.
When an origin search is executed, operation stops at the motor's Z-phase position and the origin is
determined after the origin proximity signal turns from ON to OFF during motor rotation in the direction
set by PP-19 (origin search direction).
When PP-06 and PP-07 (leftmost and rightmost digits for the origin compensation amount) are set,
positioning will be executed from this position by the amount set for origin compensation, and then that
compensated position will be taken as the mechanical origin.
DIO CN1-4
RUN RUN command
The pin No. 4 signal input turns ON the power to drive the motor and begins motor operation. If this
signal is not input (turned ON), the motor cannot be driven.
DIO CN1-5
START START
The pin No. 5 signal input executes the specified positioning (point No. input or direct input).
When this signal is input (turned ON), the motor is operated and positioning is executed based on the
positioning data.
DIO CN1-6
RESET Alarm reset
This is the alarm's external reset signal.
When this signal is input (turned ON), the alarm is cleared and the alarm output is turned ON. (The
alarm will not be cleared, however, if the alarm condition remains in effect.)
If this signal is input under normal conditions (i.e., when no alarm is generated), the motor is deceler-
ated to a stop according to the deceleration time.
When positioning is being executed according to PTP data, the point number is taken again.
When an alarm is generated, remove the cause of the alarm before beginning operation again. For
safety's sake, turn OFF the RUN command before inputting the alarm reset signal.
