3. SIGNALS AND WIRING
(2) Output device
The Connector pin No. column indicates the connector pin Nos. assigned at default. The device with
can
change the connector pin Nos. assigned by changing the parameter No. PD09 to PD11, Po08 and Po09.
The devices indicated with
cannot be used.
PT in the table indicates when using a point table, and BCD indicates when using a 6-digit BCD input with
symbol.

Functions/Applications
PT BCD
Ready RD CN6-14
RD turns ON when the servo amplifier is ready to operate after servo-on.
Trouble ALM CN6-15
ALM turns off when power is switched off or the protective circuit is activated to
shut off the base circuit. Without alarm occurring, ALM turns on within 1.5s after
power-on.
Home position return
completion
ZP CN6-16
In an absolute position system, ZP turns ON when operation is ready to start, but
turns OFF in any of the following cases.
1) Servo-on (SON) is turned OFF.
2) Forced stop (EMG) is turned OFF.
3) Reset (RES) is turned ON.
4) Alarm occurs.
5) Forward rotation stroke end (LSP) or Reverse rotation stroke end (LSN) 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 system
was changed from invalid to valid.
10) Parameter No. PA13 (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 (ZP) turns to the same
output status as Ready (RD).
Temporary stop PUS CN10-46
TSTP turns ON when deceleration is started to make a stop by Temporary
stop/Restart (TSTP). When Temporary stop/Restart (TSTP) is made valid again
to resume operation, TSTP turns OFF.
Movement finish MEND CN10-47
MEND turns ON when In position (INP) turns ON and the command remaining
distance is "0".
MEND turns ON at servo-on.
Rough match CPO CN10-48
CPO turns ON when the command remaining distance becomes less than the
rough match output range set in the parameter.
CPO turns ON at servo-on.
In position INP CN10-49
INP 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.
INP turns ON at servo-on.
