Parameter Breakdown
*
EEPROM data of servo amplifier is
abnormal.
A.03
Main Circuit Encoder
Error Detection data for power circuit is abnor-
mal.
A.04 Parameter Setting Error
*
The parameter setting is outside the
allowable setting range.
A.05
Servomotor and Ampli-
fier Combination Error Servo amplifier and servomotor capaci-
ties do no match each other.
A.10 ON OFF OFF OFF
Overcurrent or Heat Sink
Overheated
*2
An overcurrent flowed through the IGBT.
Heat sink of servo amplifier was over-
heated.
A.30
ON ON OFF OFF
Regeneration Error
Detected Regenerative circuit is faulty
Regenerative resistor is faulty.
A.32 Regenerative Overload
Regenerative energy exceeds regenera-
tive resistor capacity.
A.40
OFF OFF ON OFF
Overvoltage
Main circuit DC voltage is excessively
high.
A.41 Undervoltage
Main circuit DC voltage is excessively
low.
A.51 ON OFF ON OFF Overspeed
Rotational speed of the motor is exces-
sively high.
A.71
ON ON ON OFF
Overload: High Load
The motor was operating for several sec-
onds to several tens of seconds under a
torque largely exceeding ratings.
A.72 Overload: Low Load
The motor was operating continuously
under a torque largely exceeding ratings
A.73 Dynamic Brake Overload
When the dynamic brake was applied,
rotational energy exceeded the capacity
of dynamic brake resistor.
A.74
Overload of Surge Cur-
rent Limit Resistor The main circuit power was frequently
turned ON and OFF.
A.7A Heat Sink Overheated
**
The heat sink of servo amplifier over-
heated.
