Detection details and probable
cause
The DC voltage of the control circuit is
below the specified value.
The DC voltage in the main circuit is
abnormally high.
The DC voltage of the main circuit is
low.
A location was detected where the
main circuit AC power supply is cut off. −
Overcurrent flowed to the IGBT.
Motor power line ground fault or short circuit. √
The temperature of the Servo Drive
radiator exceeded the specified value.
Operation was performed with torque
significantly exceeding the rating for several
seconds to several tens of seconds.
The regenerative energy exceeds the
processing capacity of the
Regeneration Resistor.
An error was detected in a Servo Drive
regeneration drive Tr.
The encoder wiring is disconnected.
An encoder communications error
was detected.
Communications cannot be performed
between the encoder and the Servo
Drive.
The error counter accumulated pulse
exceeds the set value for the Error
Counter Overflow Level (Pn014).
The difference between the internal
position command speed and the
actual speed (i.e., the speed error)
exceeded the Excessive Speed Error
Setting (Pn602).
During fully-closed control, difference
between position of load from external
encoder and position of motor due to
encoder was larger than the pulse number
set by Excessive Hybrid Error Setting
(Pn332).
