error
E099 Y servo DSP and ESC
communication interrupted
E100 Y servo interrupts commu-
nication with host through
network cable
Fault Cause
1. The wiring of the cable and encod-
er cable is wrong
2. The pulse frequency output by the
controller is too large
3. The electronic gear ratio is too
large
4. The servo gain setting is too large
1. Y servo board program is an old
version
2. Mechanical stuck
1. Poor motor wiring
2. The motor is damaged
3. The Y servo board is damaged
Incorrect wiring phase sequence
Battery exhausted
Motor model does not match
1. There is a problem with the en-
coder
2. There is a problem with the direc-
tion of the drive
3. The pulse current limiting resis-
tance is large
1. Excessive load
2. Overheat protection
3. The screw or nut is damaged
– 50 –
Solution
1. Whether the wiring of the servo motor
power cable and encoder cable is cor-
rect and damaged
2. The pulse frequency output by the con-
troller is too large
3. Reduce electronic gear ratio
4. Try to adjust the servo gain manually or
automatically again
1. See "Internal Driver" - "Y Servo" on the
screen No version number indicates that
the old version needs to be returned to
the factory to update the program.
2. Check the machinery
1. Check the motor wiring
2. Replace the motor
3. Replace the Y servo board
Wiring in the correct phase sequence
