Example) For error code 100, take the corrective action for M8060.
*3 For the hexadecimal error code of the servo amplifier, the GOT displays the error code in decimal incremented by 2000.
When referring to the manual of servo amplifier by the error code displayed as a GOT system alarm, subtract 20000 from the
GOT error code and change its lower three digits to the hexadecimal number.
