17. SPEED CONTROL OPERATION
17.2.2 Detailed explanation of I/O signals
(1) Input signals (input devices)
The note signs in the remarks column indicate the following descriptions.
*1: Can be used as an external input signal of CN6 connector by setting parameter No.PD12.
*2: Can be automatically turned on by setting parameter No.PD01.
*3: Can be automatically turned on by setting parameter No.PD03.
The device whose Device No. field has an oblique line cannot be used with CC-Link.

Servo-on
Turning RYn0 turns on the base circuit, making operation ready to start.
(Servo on status)
Turning RYn0 off shuts off the base circuit, coasting the servo motor.

Forward rotation start
This is used to start the servo motor.
The following shows the rotation directions.

When RYn1 and RYn2 are turned on or off during operation, the servo
motor decelerates to a stop. In this case, the servo will not be locked.
The servo motor speed will be controlled to 0r/min, and the stop
position will not be maintained.
Forward rotation stroke end In factory setting, an external input signal (CN6-3) is enabled for the
forward rotation stroke end, and an external input signal (CN6-4) for the
reverse rotation stroke end.
In operation, short circuit between CN6-3 and DOCOM, and CN6-4 and
DOCOM. When they are opened, the servo motor stops immediately,
and the servo will be locked.
When using with CC-Link, enable the signals with parameter No.PD12.
When operating, turn RYn4 and RYn5 on. When they are turned off,
the servo motor stops immediately, and the servo will be locked. A stop
method is selectable using parameter No.PD20.
When the forward rotation stroke end and reverse rotation stroke end
are not used, set them to "automatic on" by parameter No.PD01.
