Accurax G5 AC SERVOMOTOR AND SERVO DRIVE USER'S MANUAL
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.
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.
The encoder wiring is disconnected.
Communications cannot be performed between the encoder and the driver.
The number of accumulated pulses in the error counter exceeded 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 number of
pulses set by Internal/External Feedback Pulse Error Counter Overflow
Level (Pn328).
The motor rotation speed exceeded the maximum number of rotations.
The set value for the Electronic Gear Ratio (Pn009 to Pn010, Pn500 to
Pn503) is not appropriate.
Error counter value based on the encoder pulse reference exceeded 2
(536870912).
An error was detected in the interface I/O signal.
The motor exceeded the allowable operating range set in the Overrun Limit
Setting (Pn514) with respect to the position command input.
Data in the Parameter Save area was corrupted when the power supply
was turned ON and data was read from the EEPROM.
The checksum for the data read from the EEPROM when the power supply
was turned ON does not match.
The forward drive prohibition and reverse drive prohibition inputs are both
turned OFF.
A current exceeding the Excessive Analog Input (Pn424, Pn427 or Pn430)
was applied to the analog command input (pin 14).
The voltage supplied to the absolute encoder is lower than the specified
value.
value.
The motor rotation speed exceeds the specified value when only the battery
power supply of the absolute encoder is used.
A 1-turn counter error was detected.
