When using this signal, make it usable by the setting of
parameter No.PD07 to PD09.
When the servo is off, SA will be turned OFF. When servo motor
rotation speed becomes approximately setting speed, SA will be
turned ON. When the preset speed is 20r/min or less, SA always
turns on. This signal cannot be used in position loop mode.
When using this signal, make it usable by the setting of
parameter No.PD07 to PD09.
When torque is produced level of torque set with controller, TLC
will be turned ON. When the servo is off, TLC will be turned
OFF.
When using this signal, make it usable by the setting of
parameter No.PD07 to PD09.
When the servo is off, SA will be turned OFF.
ZSP turns on when the servo motor speed is zero speed
(50r/min) or less. Zero speed can be changed using parameter
No. PC07.

ZPS turns on 1) when the servo motor is decelerated to 50r/min,
and ZPS turns off 2) when the servo motor is accelerated to
70r/min again.
ZPS 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 ZPS 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-J3-B servo amplifier.
When using this signal, make it usable by the setting of
parameter No.PD07 to PD09.
When warning has occurred, WNG turns on. When there is no
warning, WNG turns off within about 1.5s after power-on.
When using this signal, make it usable by the setting of
parameter No.PD07 to PD09.
BWNG turns on when battery cable breakage warning (92) or
battery warning (9F) has occurred.
When there is no battery warning, BWNG turns off within about
1.5s after power-on.
When using this signal, make it usable by the setting of
parameter No.PD07 to PD09.
CDPS is on during variable gain.
When using this signal, make it usable by the setting of
parameter No.PD07 to PD09.
ABSV turns on when the absolute position erased.
This signal cannot be used in position loop mode.
