Alarm code
(HEX)
Name Cause
D03
Count error Error status of a serial encoder
D08
Encoder communication
CRC error
CRC error (reception error) of a serial encoder
D09
Over speed The motor revolution speed exceeded the maximum revolution
speed (MAXV) set in the parameter.
D0A
Overload The effective output torque value exceeded the allowable value
of the motor.
D10
Overcurrent The output current of the converter part became abnormally
large.
D12
Encoder out The encoder is not connected.
D13
FPGA error Error in the FPGA operation clock
D19
Reception timeout error Error in the FPGA communication processing of a serial encoder
(After the transmission is completed and 4 µs has elapsed, the
reception start bit is still not asserted.)
D0F
IPM temperature error Abnormal heating of the converter part
E29
EEPROM error A writing signal is sent to EEPROM when access to EEPROM is
prohibited.
E3E
Parameter sum check
error
Error of sum check value within EEPROM/parameter area
E67
Motor overvoltage Voltage of the converter part increased abnormally (400 V or
more) due to regenerative voltage, etc.
EA3
AC power supply
interruption detection
error
An AC power supply interrupt was detected.
FFA
Driver part program
processing error
Error in processing of the driver part of a system program
FFB
Feedback pulse data
writing error
Feedback pulse data could not be written within the cycle.
FFD
Control power supply
voltage error
Error in the voltage of the control power supply
FFE
Current sensor error The offset adjustment amount of the current sensor exceeded
the internally specified value.
FFF
CPU error The CPU operated abnormally.
