14. TABLE OF ERROR CODES Code E-A0 E-b0 E-d0 E-E0 E-E1 Cause Home position cannot be detected (malfunction of home position sensor), or malfunction of power supply circuit board. Remedy Turn off the power and check the connection of home position sensor connector P1. You tried to change the program number when DIP switch A-8 was set to ON. Press the RESET switch. Set DIP switch A-8 to OFF before trying to change the program number. Heat sink of control circuit board is abnormally hot. Turn off the power and clean the air intake port of the box. Malfunction of EEPROM (malfunction of main circuit board). Turn off the power, and turn it back on. If the error continually occurs, contact a qualified service technician. Corrupted EEPROM data, or main PROM version has been upgraded. Press the RESET switch to reset the error. However, the data (memory switches, display and user programs) will be reset to the backup data or initialized. E-E2 Corrupted EEPROM control information data. Press the RESET switch to reset the error. However, the data (memory switches, display and user programs) will all be initialized. E-F0 Solenoid short-circuit (malfunction of main circuit board), or power relay is not operating (malfunction of power supply circuit board). Turn off the power and contact a qualified service technician. E-F1 E-F2 Bad connection in cable between power supply circuit board and main circuit board. Abnormal current detected in power supply circuit board. Turn off the power and check if connectors P16 is disconnected. Turn off the power and contact a qualified service technician. s Errors generated when optional equipment is connected Code Cause Remedy E-10 Emergency stop switch was pressed.
