Detection details and probable
cause
The DC voltage of the main circuit fell
below the specified value while the
operation command (RUN) input was ON.
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 driver 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 driver
regeneration drive Tr.
The encoder wiring is disconnected.
An encoder communications error
was detected.
Communications cannot be performed
between the encoder and the driver.
The error counter accumulated pulse
exceeds the set value for the Error
Counter Overflow Level (Pn014).
During full closing control, difference
between position of load from external
scale and position of motor due to encoder
was larger than the pulse number set by
Excessive Hybrid Error Setting (Pn332).
The motor rotation speed exceeded the set
value of the Overspeed Level set (Pn513).
The motor rotation speed exceeded the set
value of the Overspeed Level set 2 (Pn615).
A command pulse frequency error was
detected.
The pulse regeneration output
frequency exceeded the limit.
