Enabling servo-on to make the servo amplifier ready to operate will turn on RD.
SA will turn off during servo-off. When the servo motor speed reaches the following range, SA will
turn on.
Set speed ± ((Set speed × 0.05) + 20) r/min
When the preset speed is 20 r/min or less, SA always turns on.
The device cannot be used in the position control mode and torque control mode.
When the speed reaches the speed limit value in the torque control mode, VLC will turn on. When
the servo is off, TLC will be turned off.
The device cannot be used in the position control mode and speed control mode.
ZSP turns on when the servo motor speed is zero speed (50r/min) or less. Zero speed can be
changed with [Pr. PC07].

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.
When you use a linear servo motor, [r/min] explained above will be [mm/s].
When the torque reaches the torque limit value during torque generation, TLC will turn on. When
the servo is off, TLC will be turned off.
This device cannot be used in the torque control mode.
