cause of occurrence expected
• 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.
• 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.
• CN: Not connected
• Dsconnecton of operaton panel cord.
• Operaton panel has broken.
• In the case the man shaft cannot be con-
trolled.
• Motor drver has broken.
• In the case a motor sgnal cannot be nput
correctly.
• Data cannot be wrtten on the EEPROM.

Items to be checked
• Check whether the appled power voltage s
higher than the rated voltage + (plus) 10% or
more.
• Check whether 00V/200V changeover con-
nector s mproperly set.
In the aforementoned cases, POWER p.c.b s
broken.
• 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.
• Check whether the generaton resster s
connected to CN.
• 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.
• Turn the power OFF.
• 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.
• Turn the power OFF.
