Bit Name Internal state when “1” is indicated
#0 OFAL An overflow alarm is being generated inside the
digital servo.
#1 FBAL A pulse–coder disconnection alarm is being
generated.
#2 DCAL A regenerative discharge circuit alarm is being
generated in the servo amplifier (the “DC” LED of
the servo amplifier is on).
#3 HVAL An overvoltage alarm is being generated in the
servo amplifier (the “HV” LED of the servo
amplifier is on).
#4 HCAL An abnormal current alarm is being generated in
the servo amplifier (the “HC” LED of the servo
amplifier is on).
#5 OVC An overcurrent (overload) alarm is being
generated in the servo amplifier.
#6 LVAL A low voltage alarm is being generated in the servo
amplifier (the “LV” LED of the servo amplifier is
on).
#7 OVL An overload alarm is being generated in the servo
motor or the servo amplifier. If the alarm is
generated in the servo amplifier, overheat occurs
in the servo amplifier, the separate discharge unit,
or the power transformer (the “OH” LED of the
servo amplifier is on).
