Zero speed ZSP ZSP turns on when the servo motor speed is zero speed (50r/min) or less. Zero
speed can be changed using parameter No. PC17.

ZSP turns on 1) when the servo motor is decelerated to 50r/min, and ZSP turns
off 2) when the servo motor is accelerated to 70r/min again. ZSP turns on 3)
when the servo motor is decelerated again to 50r/min, and turns off 4) when the
servo motor speed has reached -70r/min. 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 20r/min for this servo amplifier.
Limiting torque TLC TLC turns on when the torque generated reaches the value set to the Forward
torque limit (parameter No. PA11), Reverse torque limit (parameter No. PA12) or
analog torque limit (TLA).
Warning WNG WNG turns ON when a warning occurs.
When no warning has occurred, WNG turns OFF within about 1s after power-on.
Electromagnetic brake
interlock
MBR MBR turns OFF at servo-off or alarm occurrence. At alarm occurrence, it turns
OFF independently of the base circuit status.
Dynamic brake interlock DB DB turns off simultaneously when the dynamic brake is operated. When using
the external dynamic brake on the servo amplifier of 11 kW or more, this device
is required. (Refer to section 13.6.) For the servo amplifier of 7kW or less, it is
not necessary to use this device.
Battery warning BWNG BWNG turns ON when Open battery cable warning (A92) or Battery warning
(A9F) occurs. When no battery warning has occurred, BWNG turns OFF within
about 1s after power-on.
Position range POT POT turns ON when the actual current position falls within the range set in the
parameter. It is OFF when a home position return is not yet completed or while
the base circuit is off.
Variable gain selection CDPS CDPS is on during gain changing.
Command speed
reached
SA SA turns on when servo-on (SON) is on and the commanded speed is at the
target speed.
SA always turns on when servo-on (SON) is on and the commanded speed is
0r/min.
SA turns off when servo-on (SON) is off or the commanded speed is in
acceleration/deceleration.
