Alarm Meaning
The main circuit DC voltage is too high.
The main circuit DC voltage is too low.
The motor exceeded the maximum
speed.
• Rotary Servomotor: The pulse output
speed for the setting of Pn212 (Encoder
Output Pulses) was exceeded.
• Linear Servomotor: The motor speed
upper limit for the setting of Pn281
(Encoder Output Resolution) was
exceeded.
Abnormal oscillation was detected in the
motor speed.
Vibration was detected during autotuning
for the tuning-less function.
The setting of Pn385 (Maximum Motor
Speed) is greater than the maximum
motor speed.
The Servomotor was operating for several
seconds to several tens of seconds under
a torque that largely exceeded the rating.
The Servomotor was operating continu-
ously under a torque that exceeded the
rating.
When the dynamic brake was applied,
the rotational or linear kinetic energy
exceeded the capacity of the dynamic
brake resistor.
The main circuit power supply was fre-
quently turned ON and OFF.
The surrounding temperature of the con-
trol PCB is abnormal.
The surrounding temperature of the
power PCB is abnormal.
An error occurred in the temperature sen-
sor circuit.
The fan inside the SERVOPACK stopped.
The power supplies to the encoder all
failed and the position data was lost.
There is an error in the checksum results
for encoder memory.
The battery voltage was lower than the
specified level after the control power
supply was turned ON.
There is an internal data error in the
encoder.
The encoder was operating at high speed
when the power was turned ON.
The internal temperature of encoder is
too high.
