Functions/Applications

Trouble ALM

CN1B

18

ALM-SG are disconnected when power is switched off or the protective circuit is

activated to shut off the base circuit. Without alarm, ALM-SG are connected within

about 1s after power-on.

Ready RD

CN1B

19

RD-SG are connected when the servo is switched on and the servo amplifier is

ready to operate.

Movement finish

MEND

CN1B

6

MEND-SG are connected when the in-position device (INP) turns on and the

command remaining distance is "0". (Refer to section 3.4.2.)

MEND-SG are connected at servo on.

Rough match

CPO

CN1B

4

CPO-SG are connected when the remaining command distance falls within the

parameter-set rough match output range.

This signal is not output while the base circuit is off. Servo-on connects CPO-SG.

During home position return and manual operation, CPO-SG are kept connected.

Home position return

completion

ZP CN1A

18

ZP-SG are connected on completion of home position return.

In the absolute position system, ZP-SG are connected when the servo amplifier is

ready to operate but are disconnected if.

1) SON-SG are opened.

2) EMG-SG are opened.

3) RES-SG are shorted.

4) Alarm occurs.
5) Limit switch opens.

6) Home position return has not been made after the purchase of the product.

7) Home position return has not been made after the occurrence of absolute position

erasure (AL. 25) or absolute position counter warning (AL. E3).

8) Home position return has not been made after the changing of the electronic gear

value.

9) Home position return has not been made after the absolute position system was

made valid.

10) The ST1 coordinate system (000 in parameter No.1) has been changed.

11) Software limit is valid.

12) Home position return completion.

If the status is not any of 1) to 12) and the home position setting has already been

completed at least once, home position return completion (ZP) is placed in the same

output status as ready (RD).

Electromagnetic brake

interlock

MBR

In the servo-off or alarm status, MBR-SG are disconnected.

When an alarm occurs, they are disconnected independently of the base circuit

status.

Position range

POT

Position range (POT) is on when the current position is within the range set in
parameters No. 50 to 53. If the current position is within the set range, the device

is off when a home position return is not yet complete or while the base circuit is off

(during servo off, alarm occurrence or alarm reset).

Warning WNG

When warning has occurred, WNG-SG are connected.

When there is no warning, WNG-SG are disconnected within about 1s after power-
on.

Battery warning

BWNG

BWNG-SG are connected when battery cable breakage warning (AL.92) or battery

warning (AL.9F) has occurred.

When there is no battery warning, BWNG-SG are disconnected within about 1s

after power-on.

Limiting torque

TLC

TLC-SG are connected when the torque generated reaches the value set to the

internal torque limit 1 (parameter No. 28), internal torque limit 1 (parameter No.

29) or analog torque limit (TLA).

Temporary stop

PUS

PUS-SG are connected when deceleration to a stop is started by the temporary stop
signal. PUS-SG is disconnected when operation is resumed by making the

temporary stop signal valid again.

In position

INP

INP-SG are connected when the number of droop pulses is in the preset in-position

range. The in-position range can be changed using parameter No. 6.

When the in-position range is increased, INP-SG may be kept connected during
low-speed rotation. Servo-on connects INP-SG.
