OMNUC G5-Series AC Servo Drives Users Manual (Built-in MECHATROLINK-II communications type)
Detection details and
probable cause
The DC voltage of the main circuit fell
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).
During full closing control, difference
between the load position from
external encoder and the motor
position from to encoder was larger
than the pulse set by the Internal/
External Feedback Pulse Error
Counter Overflow Level (Pn328).
