A-axis zero speed ZSP-A DO-1
B-axis zero speed ZSP-B
When using this signal, make it usable by the setting of parameter No.PD07
or PD09.
ZSP-A/ZSP-B turns on when the servo motor speed is zero speed (50r/min)
or less. Zero speed can be changed using parameter No.PC07.

ZSP-A/ZSP-B turns on 1) when the servo motor is decelerated to 50r/min,
and ZSP-A/ZSP-B turns off 2) when the servo motor is accelerated to
70r/min again.
ZSP-A/ZSP-B turns on 3) when the servo motor is decelerated again to
50r/min, and turns off 4) when the servo motor speed has reached -70r/min.
The range from the point when the servo motor speed has reached ON level,
and ZSP-A/ZSP-B turns on, to the point when it is accelerated again and has
reached OFF level is called hysteresis width.
Hysteresis width is 20r/min for the MR-J3W-B servo amplifier.
A-axis warning WNG-A
DO-1
B-axis warning WNG-B
When using this signal, make it usable by the setting of parameter No.PD07
or PD09.
When warning has occurred, WNG-A/WNG-B turns on. When there is no
warning, WNG-A/WNG-B turns off within about 1.5s after power-on.
A-axis battery
warning BWNG-A DO-1
B-axis battery
warning BWNG-B
When using this signal, make it usable by the setting of parameter No.PD07
or PD09.
BWNG-A/BWNG-B turns on when battery cable disconnection warning
(92.1) or battery warning (9F.1) has occurred. When there is no battery
warning, BWNG-A/BWNG-B turns off within about 1.5s after power-on.
A-axis variable
gain selection CDPS-A DO-1
B-axis variable
gain selection CDPS-B
When using this signal, make it usable by the setting of parameter No.PD07
or PD09.
CDPS-A/CDPS-B is on during variable gain.
A-axis absolute
position erasing ABSV-A DO-1
B-axis absolute
position erasing ABSV-B
When using this signal, make it usable by the setting of parameter No.PD07
or PD09.
ABSV-A/ABSV-B turns on when the absolute position erased.
This signal cannot be used in the speed loop mode and the torque loop
mode.
