CN3-15 When an alarm occurs, ALM turns off.
When no alarm has occurred, ALM turns on in 4 s to 5 s after power-on.
When [Pr. PD39] is set to "_ _ 1 _", ALM turns off if an alarm or a warning
occurs.
When an alarm occurs, ALMWNG turns off.
When a warning occurs (except for [AL. 9F Battery warning]), ALMWNG
turns on and off repeatedly approximately every 1 s.
When no alarm or warning has occurred, ALMWNG turns on in 4 s to 5 s
after power-on.
When a warning occurs, WNG will turn on. When no warning has occurred,
WNG turns off in 4 s to 5 s after power-on.
When [AL. 92 Battery cable disconnection warning] or [AL. 9F Battery
warning] has occurred, BWNG turns on. When no battery warning has
occurred, BWNG turns off in 4 s to 5 s after power-on.
When [AL. 9F Battery warning] occurs, BW9F turns on.
CN3-14 When the servo-on is on and the servo amplifier is ready to operate, RD
turns on.
CN3-22 When the number of droop pulses is in the preset in-position range, INP will
turn on. The in-position range can be changed with [Pr. PA10]. When the in-
position range is increased, INP may be always on during low-speed
rotation.
INP turns on with servo-on.
TLC turns on when a generated torque reaches a value set with any of [Pr.
PA11 Forward torque limit], [Pr. PA12 Reverse torque limit], or TLA (Analog
torque limit).
ZSP turns on when the servo motor speed is zero speed or less. Zero
speed can be changed with [Pr. PC17].

detection)
ZSP turns on when the servo motor is decelerated to 50 r/min (at 1)), and
turns off when the servo motor is accelerated to 70 r/min again (at 2)).
ZSP turns on when the servo motor is decelerated again to 50 r/min (at 3)),
and turns off when the servo motor speed has reached -70 r/min (at 4)).
The range from the point when the servo motor speed has reached the on-
level, and ZSP turns on, to the point when it is accelerated again and has
reached the off-level is called hysteresis width.
Hysteresis width is 20 r/min for this servo amplifier.
When using the device, set operation delay time of the electromagnetic
brake in [Pr. PC16].
When a servo-off status or alarm occurs, MBR will turn off.
SA turns on when the command speed reaches the target speed in servo-
on status.
SA is always on when the command speed is 0 r/min in servo-on status.
SA turns off in servo-off status or when the command speed is in
acceleration/deceleration.
