E810 Solenoid short-circuit When the short-circuited solenoid is desired to be driven. Check whether the solenoid is short-circuited.

E811 Overvoltage 1. When voltage upper than guaranteed one is 1. Check whether the applied power voltage is higher than the rated voltage + (plus)

inputted. 10% or more.

2. When 200V is inputted for 100V setting. 2. Check whether 100V/200V changeover connector is set by mistake.

In the above cases, POWER circuit board has broken.

E813 Low voltage 1. When voltage lower than guaranteed one is 1. Check whether the votage is lower than the rated voltagw - (minus) 10% or less.

inputted. 2. Check whether 100V/200V changeover connector is set by mistake.

2. When 100V is inputted for 200V setting.

E920 GA failure Abnormality of gate array When return is not performed even after turning OFF the power, the possibility of gate

array breakage is large.

E922 Main shaft motor control is impossible. When main shaft motor cannot be controlled. Turn OFF the power.

E924 Motor driver failure Motor driver has broken. Turn OFF the power.

E940 Bird's nest sequence error Bird's nest prevention sequence is not completed. Turn OFF the power.

E941 GA failure Abnormality of gate array When return is not performed even after turning OFF the power, the possibility of gate

array breakage is large.

E942 EEPROM failure Writing is not completed even after the lapse of 10 Turn OFF the power.
