3.5.2 Detailed explanation of I/O signals

(1) Input signals
The signal whose Device No. field has an oblique line cannot be used in CC-Link.
Signal name
Servo-on
Forward rotation start
Reverse rotation start
Proximity dog
Description
Turning RYn0 ON powers on the base circuit, making
operation ready to start. (Servo on status)
Turning it OFF powers off the base circuit, coasting the
servo motor. (Servo off status)
1. In absolute value command system
Turning RYn1 ON for automatic operation executes
positioning once on the basis of the position data set to the
point table.
Turning RYn1 ON for a home position return immediately
starts a home position return.
Keeping RYn1 ON for JOG operation performs rotation in
the forward rotation direction.
Forward rotation indicates the address increasing
direction.
2. In incremental value command system
Turning RYn1 ON for automatic operation executes
positioning once in the forward rotation direction on the
basis of the position data set to the point table.
Turning RYn1 ON for a home position return immediately
starts a home position return.
Keeping RYn1 ON for JOG operation performs rotation in
the forward rotation direction.
Forward rotation indicates the address increasing
direction.
Use this device in the incremental value command system.
Turning RYn2 ON for automatic operation executes
positioning once in the reverse rotation direction on the
basis of the position data set to the point table.
Keeping RYn2 ON for JOG operation performs rotation in
the reverse rotation direction.
Reverse rotation indicates the address decreasing
direction.
Reverse rotation start (RYn2) is also used as the start
signal of the high-speed automatic positioning function to
the home position.
In the shipment status, the proximity dog external input
signal (CN1B-7) is valid. For use in CC-Link, make it
usable in parameter No. 116. When RYn3 is turned ON,
the proximity dog is detected. The polarity of dog detection
can be changed using parameter No. 8.
