3. CC-LINK COMMUNICATION FUNCTIONS
(2) Output signals (Output device)
POINT
The output devices can be used for both the RX of CC-Link and the external
output signals of CN6 connector.
The signal whose Device No. field has an oblique line cannot be used in CC-Link.

Ready In the factory-shipped status, a ready is assigned to the CN6-14 pin as an
external output signal. RXn0 turns ON when the servo amplifier is ready to
operate after servo-on. RXn0 RXn0
In position RXn1 turns ON when the droop pulse value is within the preset in-position
range.
The in-position range can be changed using parameter No.PA10.
Increasing the in-position range may result in a continuous conduction status
during low-speed rotation.
RXn1 turns ON at servo-on. RXn1 RXn1
Rough match RXn2 turns ON when the command remaining distance becomes less than the
rough match output range set in the parameter. This is not outputted during
base circuit shut-off.
RXn2 turns ON at servo-on. RXn2 RXn2
Home position return
completion In the factory-shipped status, the home position return completion is assigned to
the CN6-16 pin as an external output signal. RXn3 turns ON when a home
position return is completed. RXn3 turns ON at completion of a home position
return.
In an absolute position detection system, RXn3 turns ON when operation is
ready to start, but turns OFF in any of the following cases.
1) Servo-on (RYn0) is turned OFF.
2) Forced stop (EMG) is turned OFF.
3) Reset (RY(n 1)A or RY(n 3)A) is turned ON.
4) Alarm occurs.
5) Forward rotation stroke end (RYn4) or Reverse rotation stroke end (RYn5) is
turned OFF.
6) Home position return has not been made after product purchase.
7) Home position return has not been made after occurrence of Absolute
position erase (A25) or Absolute position counter warning (AE3).
8) Home position return has not been made after electronic gear change.
9) Home position return has not been made after the absolute position detection
system was changed from invalid to valid.
10) Parameter No.PA14 (Rotation direction selection) has been changed.
11) Software limit is valid.
12) While a home position return is being made.
When any of 1) to 12) has not occurred and a home position return is already
completed at least once, Home position return completion (RXn3) turns to the
same output status as Ready (RXn0).
RXn3 RXn3
Limiting torque RXn4 turns ON when the torque is reached at the time of torque generation. RXn4 RXn4
Electromagnetic brake
interlock RXn6 turns OFF at servo-off or alarm occurrence. At alarm occurrence, it turns
OFF independently of the base circuit status. RXn6 RXn6
Temporary stop RXn7 turns ON when deceleration is started to make a stop by Temporary
stop/Restart (RYn7). When Temporary stop/Restart (RYn7) is made valid again
to resume operation, RXn7 turns OFF. RXn7 RXn7
Monitoring Refer to Monitor output execution demand (RYn8). RXn8 RXn8
