Malfunction ALM CN1-48 When an alarm occurs, ALM will turn off.
When an alarm does not occur, ALM will turn on after 2.5 s to 3.5 s after
power-on.
When [Pr. PD34] is "_ _ 1 _", an alarming or warning will turn off ALM.
DO-1
Ready RD CN1-49 Enabling servo-on to make the servo amplifier ready to operate will turn on
RD.
DO-1
In-position INP CN1-22
CN1-24
When the number of droop pulses is in the preset in-position range, INP
will turn on. The in-position range can be changed using [Pr. PA10]. When
the in-position range is increased, INP may be on during low-speed
rotation.
INP turns on when servo-on turns on.
DO-1
Speed reached SA When the servo motor speed reaches approximately setting speed, SA will
turn on. When the preset speed is 20 r/min or less, SA always turns on.
SA does not turn on even when the SON (Servo-on) is turned off or the
servo motor speed by the external force reaches the preset speed while
both ST1 (Forward rotation start) and ST2 (reverse rotation start) are off.
DO-1
Limiting speed VLC CN1-25 VLC turns on when speed reaches a value limited with any of [Pr. PC05
Internal speed limit 1] to [Pr. PC11 Internal speed limit 7] or VLA (Analog
speed limit).
This turns off when SON (Servo-on) turns off.
DO-1
Limiting torque TLC 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).
DO-1
Zero speed
detection
ZSP CN1-23 ZSP turns on when the servo motor speed is zero speed (50r/min) or less.
Zero speed can be changed with [Pr. PC17].

4)
ZSP will turn on when the servo motor is decelerated to 50 r/min (at 1)),
and will turn off when the servo motor is accelerated to 70 r/min again (at
2)).
ZSP will turn on when the servo motor is decelerated again to 50 r/min (at
3)), and will turn 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 on
level, and ZSP turns on, to the point when it is accelerated again and has
reached off level is called hysteresis width.
Hysteresis width is 20 r/min for this servo amplifier.
DO-1
Electromagnetic
brake interlock
MBR CN1-25 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.
DO-1
Warning WNG When warning has occurred, WNG turns on. When a warning is not
occurring, turning on the power will turn off WNG after 2.5 s to 3.5 s.
DO-1
Battery warning BWNG BWNG turns on when [AL. 92 Battery cable disconnection warning] or [AL.
9F Battery warning] has occurred. When the battery warning is not
occurring, turning on the power will turn off BWNG after 2.5 s to 3.5 s.
