ZSP (Zero speed detection)
If the servo motor speed is zero speed or less, ZSP will turn on. Zero speed can be changed with [Pr. PC07].
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)
If the torque reaches the torque limit value when torque is generated, TLC will turn on. TLC will turn off in the servo-off state.
In the torque mode, TLC is off.
Output device explanation [A]
■ MBR (Electromagnetic brake interlock)
MBR is off in the servo-off state or at alarm occurrence.
If using the device, set an operation delay time of the electromagnetic brake in [Pr. PC16].
■
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.
