10 Troubleshooting and Maintenance
Description and error 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).
The difference between the internal
position command speed and the actual
speed (i.e., the speed error) exceeded the
Excessive Speed Error Setting (Pn602).
The motor rotation speed exceeded the
value set on the Overspeed Level set
(Pn513).
The motor rotation speed exceeded the
value set on the Overspeed Level set 2
(Pn615).
A command pulse frequency error was
detected.
The command pulse divider or multiplier is
not suitable.
The pulse regeneration output frequency
exceeded the limit.
