Output device explanation [A]
■MBR (Electromagnetic brake interlock)
MBR is off in the servo-off state or at an alarm occurrence.
If using the device, set an operation delay time of the electromagnetic brake in [Pr. PC16].
For details. refer to "Electromagnetic brake interlock function" in the following manual.

■VLC (Limiting speed)
In the torque mode, VLC will turn on if the speed reaches the value limited with any of [Pr. PC05] to [Pr. PC11] or VLA (Analog
speed limit). VLC will turn off in the servo-off state.
■ZSP (Zero speed detection)
If the servo motor speed is the zero speed or less, ZSP will turn on. The zero speed can be changed with [Pr. PC17]. The
following shows an example when the initial value (50) is set in [Pr. PC17].
OFF level
70 r/min
ON level
50 r/min

ZSP
(Zero speed detection)
OFF
ZSP will turn on when the servo motor speed is reduced to 50 r/min (at (1)), and will turn off when the servo motor is increased
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
reaches -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 the
speed has increased again and reached the off-level is called a hysteresis width.
The hysteresis width is 20 r/min for this servo amplifier.
If using a linear servo motor, replace [r/min] with [mm/s].
■TLC (Limiting torque)
When torque is generated, TLC will turn on if the torque reaches the torque limit value set with any of [Pr. PA11], [Pr. PA12], or
TLA (Analog torque limit).
■ABSB0 (ABS transmission data bit 0)
This is used to output ABS transmission data bit 0. If the absolute position detection system by DIO is selected while [Pr.
PA03.0] is set to "1", ABSB0 will be assigned to the CN3-22 pin only in the ABS transfer mode.

■ABSB1 (ABS transmission data bit 1)
This is used to output ABS transmission data bit 0. If the absolute position detection system by DIO is selected while [Pr.
PA03.0] is set to "1", ABSB1 will be assigned to the CN3-23 pin only in the ABS transfer mode.

■ABST (ABS transmission data ready)
This is used to output ABS transmission data ready. If the absolute position detection system by DIO is selected while [Pr.
PA03.0] is set to "1", ABST will be assigned to the CN3-25 pin only in the ABS transfer mode.
