read only
E102 Y Servo PDO does not
have an index to find
E103 Y servo PDO setting syn-
chronization time out of
range
E104 Y servo PDO data out of
range
E105 Y servo UVW ground fault
E106 Y servo inertia identification
failed
E107 Y servo encoder EEPROM
read and write failed
E108 Y servo position positive
limit
E109 Y servo position negative
limit
E110 Y servo electronic gear
ratio setting range is wrong
E111 Y servo input pulse fre-
quency too high error
E112 Spindle hardware protec-
tion
E113 Broken spindle encoder
E114 Spindle encoder AB inter-
ference
E115 Spindle encoder Z interfer-
ence
E116 Spindle multi turn data out
of range
E117 Spindle absolute encoder
overheating
E118 Spindle battery voltage is
too low
E119 Spindle multi turn position
is missing
E120 Spindle motor overload
Fault Cause
1. Wrong phase sequence
2. The power supply voltage is too
high
1. The motor is broken or the motor
wire is damaged and short circuit-
ed
2. The motor is stuck
3. The power board spindle module
is damaged
1. Poor contact or broken wire of the
spindle encoder
2. The spindle motor is damaged
1. The power board program is the
old version
2. Poor contact or broken wire of the
spindle encoder

Spare alarm
1. Check and replace the motor
2. Check the machinery
3. Replace the power board
1. Check the spindle encoder line
2. Replace the spindle motor
1. Look at the screen "Internal Drive" -
"Version Number", 1 means the old ver-
sion needs to be returned to the factory
to update the program
2. Check the encoder cable
