3. Please confirm if Cn030 is the correct motor/driver matching; please refer to
“Servo driver and servo motor matching comparison table” for Cn030 motor
code.
4. Check if motor grounding end is grounded correctly. If the encoder signal wire
is separated from the power of the circuit with large current to avoid any
generation of interferences source. If the encoder wire uses separation net.

AL.007
Multifunction Contact Planning
Error
CiA402 Error Code 0x5441-01-0007
Alarm Cause
Digital input/output contact function planning error.
1. Several functions of the set digital input contact (DI-1~DI-12) are duplicate but
contact potential is asynchronous.
2. Several functions are duplicate in the set digital output contact function (DO-
1~DO-4).
Check and
Handling
1. Check whether the Digital Input Contact Function Planning Parameters
( Hn601~Hn612) are corrected: DI-1~DI-12 pin function can be repeated, but
the pin action electrical potential of repeated function must be the same.
2. Check if output contact function parameter (Hn613~Hn616) planning is correct:
DO-1~DO-4 pin function cannot be duplicate.

AL.008 Parameter Data Read/Write Error CiA402 Error Code 0x5500-01-0008
Alarm Cause
An Error occurred when Writing the Parameter.
1. Parameter data write-in error.
2. The set parameter value exceeds reasonable range when using specific
functions.
3. Driver hardware failure.
Check and
Handling
1. Please rewrite new parameter value.
2. Pleaseconfirm the modified parameter valueis within reasonable range.
3. If the alarm still occurs after all connectors removed, parameters (Cn029=1)
reset and rebooting, please replace the driver.
