9 Troubleshooting
Root Cause
Confirming Method
Solution
2. An error occurs when
reading/writing the RS485
encoder parameters.
If the fault persists after the servo
drive is powered off and on several
times, the encoder is faulty.
Replace the servo motor.

EB01.1: Position reference increment too large for once
Cause
Confirming Method
Solution
1. The target position
increment is too large.
Check the variation value
between two adjacent target
positions by using the software
tool.
1. Check whether the maximum motor speed
fulfills the application requirement. If yes, reduce
the target position reference increment, which
is to lower the profiled reference speed. If not,
replace the servo motor.
2. Before switching the modes or enabling the
servo drive, check whether the target position is
aligned with current position feedback.
3. The communication time sequence of the host
controller is abnormal, leading to slave data
receiving error. Check the communication time
sequence of the host controller.
■
EB01.2: Position reference increment too large continuously
Direct cause:
The target position increment exceeds the limit value N times consecutively.
Root Cause
Confirming Method
Solution
1. The target position
increment is too large.
Check the variation value
between two adjacent target
positions by using the software
tool.
1. Check whether the maximum motor speed
fulfills the application requirement. If yes, reduce
the target position reference increment, which
is to lower the profiled reference speed. If not,

3. The communication time sequence of the host
controller is abnormal, leading to slave data
receiving error. Check the communication time
sequence of the host controller.

EB01.3: Command overflow
Cause
Confirming Method
Solution
The target position is still in
the process of transmission
when the servo limit or
software limit signal is
activated and the 32-bit
upper/low limit is reached.
Check whether the host controller
keeps outputting commands
when the overtravel warning
occurs.
Detect the servo limit signal (bit0 and bit1 of 60FD
recommended) through the host controller and
stop the host controller from transmitting the limit
direction command after the servo limit signal is
activated.
