Problem
External thermal trip • An external thermal trip is input.
• PTC protection worked.
Emergency stop • During automatic operation or remote
operation, a stop command is entered
from the operation panel or a remote
input device.
EEPROM fault 1 • A data writing error occurs.
EEPROM fault 2 • Power supply is cut off during
operation and data writing is aborted.
EEPROM fault 3 • A data reading error occurred.
• The control RAM is defective.
Main unit RAM fault
Main unit ROM fault • The control ROM is defective.
• The control CPU is defective.
CPU fault 1
Communication error • An error arises during serial
communication.
Current detector fault • The current detector is defective.
• The error was occurred during Network

current detection level during operation.
Trip
Undervoltage trip • The input voltage (in the main circuit) is
(main circuit) too low.
Ground fault trip • A ground fault occurs in the output cable
or the motor.
Auto-tuning error • Check the motor parameter
• The motor with the capacity of 2 classes or less than the inverter is used.
• The output cable is too thin.
• The motor is rotating.
• The inverter is used for loads other than those of three-phase induction motors.
• Circuit board is changed.
