Dynamic brake overload
(Dynamic Brake Overload)
Overload is detected in dynamic brake resistance.
The rotating energy at dynamic brake stop is out of allowed
value, or motor is driven by external force. Please re-check and
change operating status, such as reducing command speed,
reducing moment of load inertia or reducing the stop frequency
of DB.
Please contact the nearest sales agent of our company when
the founded problem can't be solved even if the power supply of
control circuit is ON again.
Alarm detection level is only 50% of normal value only when the
power supply of control circuit is ON next time after alarm.

Surge current overload
(Surge Current Overload)
The allowed frequency of surge current limit resistance at
power ON/OFF of main circuit is execeded.
Please reduce the frequency of power ON/OFF of main circuit.

7A0
Heat sink overheated
(Heat Sink Overheated)
The heat sink temperature of servo amplifier is over 100℃.
(1) The ambient temperature is too high. Please keep the
ambient temperature of servo amplifier within specified
value.
(2) It operates with overload or exceeding regenerative
processing capacity. Please re-check and change load and
operating conditions.
(3) Operation is executed by resetting overload alarm through
power OFF. Please re-check and change the method for
alarm reset.
Please contact the nearest sales agent of our company when
the founded problem can't be solved even if the power supply
of control circuit is ON again.

Built-in fan stopped (Built-
in Fan Stopped)
The built-in fan inside servo amplifier stops.
Please check whether there is any foreign matter in fan, and
remove it if there is.
Please contact the nearest sales agent of our company when
the founded problem can't be solved even if the power supply
of control circuit is ON again.

*Encoder backup need
ABS setup
(*
ENC Backup Need
AbsSetup
)
Position data is cleared due to low voltage of encoder power
supply.
(1) Please execute "ABS encoder setting" when ABS encoder
is powered ON for the first time.
(2) The battery voltage is low or the battery has been
removed. Please replace battery or check whether the
power supply of encoder works normally before executing
"ABS encoder setting".
Please contact the nearest sales agent of our company when
the founded problem can't be solved even if the power supply
of control circuit is ON again.

*Encoder error 0 need ABS
setup
(*ENC Error 0 Need
AbsSetup)
Internal parameter error occurs for encoder.
Please execute ABS encoder setting.
Please contact the nearest sales agent of our company when
the founded problem can't be solved even if the power supply
of control circuit is ON again.

ABS encoder battery alarm
(Abs Encoder Battery Alm)
Battery voltage error is detected when control circuit is
powered ON.
(1)The battery voltage of ABS encoder is less than 2.7V. Please
replace battery.
(2) Battery connection is wrong. Please check wiring.

*Encoder error 1
(*Encoder Error 1)
Internal parameter error occurs for encoder.
Encoder misoperation occurs due to noise. Please keep away
from noise source (such as electromagnetic switches) when in
use.
Please contact the nearest sales agent of our company when
the founded problem can't be solved even if the power supply
of control circuit is ON again.

*Encoder overspeed
(*Encoder Overspeed)
Motor rotation is detected when control circuit is powered ON.
Servo motor rotates at the speed of over 200min
-1
when
control circuit is powered ON. Please check the servo motor
speed when power is ON.
Please contact the nearest sales agent of our company when
the founded problem can't be solved even if the power supply
of control circuit is ON again.

*Encoder overheat
(*Encoder Overheat)
Overheat inside encoder is detected.
(1) The ambient temperature of servo amplifier is too high.
Please re-check and change cooling conditions so that the
ambient temperature becomes less than 40.
(2) Motor is overheated due to higher load condition. Please
check operating conditions and load.
