Error detection
Description
Control power supply undervoltage
The DC voltage of the main circuit fell below the specified value.
Overvoltage
The DC voltage in the main circuit is abnormally high.
Main power supply undervoltage
The DC voltage of the main circuit is low.
Overcurrent
Overcurrent flowed to the IGBT. Motor power line ground fault or short
circuit.
Drive overheat
The temperature of the drive radiator exceeded the specified value.
Overload
Operation was performed with torque significantly exceeding the rating for
several seconds to several tens of seconds.
Regeneration overload
The regenerative energy exceeds the processing capacity of the
Regeneration Resistor.
Encoder communications error
The encoder wiring is disconnected.
Encoder communications data error
Communications cannot be performed between the encoder and the drive.
Error counter overflow
The number of accumulated pulses in the error counter exceeded the set
value for the Error Counter Overflow Level (Pn014).
Excessive hybrid error
During full closing control, difference between position of load from external
encoder 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).
Overspeed
The motor rotation speed exceeded the maximum number of rotations.
Electronic gear setting error
The set value for the Electronic Gear Ratio (Pn009 to Pn010) is not
appropriate.
Error counter overflow
Error counter value based on the encoder pulse reference exceeded 2
27
(134217728).
Safety input error
Either the Safety input 1 or 2 is off, or both of them are off.
Interface I/O setting error
An error was detected in the interface I/O signal.
Overrun limit error
The motor exceeded the allowable operating range set in the Overrun Limit
Setting (Pn514) with respect to the position command input.
Parameter error
Data in the Parameter Save area was corrupted when the power supply
was turned ON and data was read from the EEPROM.
Parameters destruction
The checksum for the data read from the EEPROM when the power supply
was turned ON does not match.
Drive prohibition input error
The forward drive prohibition and reverse drive prohibition inputs are both
turned OFF.
Absolute encoder system down error
The voltage supplied to the absolute encoder is lower than the specified
value.
Absolute encoder counter overflow error The multi-rotation counter of the absolute encoder exceeds the specified
value.
Absolute encoder overspeed error
The motor rotation speed exceeds the specified value when only the battery
power supply of the absolute encoder is used.
Absolute encoder initialization error
An error was detected during the absolute encoder initialization.
Absolute encoder 1-rotation counter
error
A 1-turn counter error was detected.
Absolute encoder multi-rotation counter
error
A multi-rotation counter error or phase-AB signal error was detected.
