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 Main shaft hardware pro-
tection
E113 Broken main shaft encoder
E114 Main shaft encoder AB
interference
E115 Main shaft encoder Z inter-
ference
E116 Main shaft multi turn data
out of range
E117 Main shaft absolute encod-
er overheating
E118 Main shaft battery voltage
is too low
E119 Main shaft multi turn posi-
tion is missing
E120 Main shaft 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 main shaft mod-
ule is damaged
1. Poor contact or broken wire of the
main shaft encoder
2. The main shaft motor is damaged
1. The power board program is the
old version
2. Poor contact or broken wire of the
main shaft encoder

Spare alarm
1. Check and replace the motor
2. Check the machinery
3. Replace the power board
1. Check the main shaft encoder line
2. Replace the main shaft 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
