E8
Overvoltage
• When voltage hgher than guaranteed one
s nputted.
• 200V has been inputted to 100V specifica
-
tons.
• 220V s appled to 20V box.
• CE : 400V s appled to 230V box.
• Check whether the appled power voltage s
higher than the rated v (plus) 10% or
more.
• Check whether 00V/200V changeover con-
nector s mproperly set.
In the aforementoned cases, POWER p.c.b s
broken.
E83
Low voltage
• When voltage lower than guaranteed one
s nputted.
• 100V has been inputted to 200V specifica
-
tons.
• 20V s appled to 220V box.
• Inner crcut s broken by the appled over-
voltage.
• Check whether the voltage s lower than the
rated voltage - (mnus) 0% or less.
• Check whether 00V/200V changeover con-
nector s mproperly set.
• Check whether fuse or regeneratve ress-
tance s broken.
E85
Regeneraton resstor s not
connected
• CN: Not connected
• Check whether the generaton resster s
connected to CN.
E906
Operaton panel transms-
son falure
• Dsconnecton of operaton panel cord.
• Operaton panel has broken.
• Check the operaton panel connector (CN38)
for loose connecton and dsconnecton.
• Check whether the operaton panel cord has
broken snce the cord s caught n the ma-
chne head.
E922
Man shaft uncontrollable
• In the case the man shaft cannot be con-
trolled.
• Turn the power OFF.
E924
Motor drver falure
• Motor drver has broken.
E930
Faulty encoder
• In the case a motor sgnal cannot be nput
correctly.
• Check the motor sgnal connector (CN30) for
looseness and slp-off.
• Check whether the motor sgnal cord s
caught n the machne head or has a break.
E93
Motor hole sensor falure
E942
Faulty EEPROM
• Data cannot be wrtten on the EEPROM.
• Turn the power OFF.
No.
