If there is interference, check the following:
6.
Make sure the servo motor is properly grounded and connect the ground
(a)
of the UVW connector (green) to the servo drive heat sink.
Use shielded cable for the feedback signal cable. Make sure the signal
(b)
cable is separated from the power supply or any high-current cables to
avoid interference.

Condition:
The initial magnetic field detection is not complete because the motor moved
1.
too far.
When the servo is on, the servo automatically detects the magnetic field.
2.
If the detection is not complete in 4 seconds, this alarm is triggered.
Cause:
When you choose not to install the Hall sensor (set PM.003.Y to 0 for not using the
Hall sensor), the servo automatically detects the magnetic field when Servo On.
This alarm is displayed when the servo cannot detect the magnetic field.
To make sure that the source of the feedback signal is correct, check the
1.
PM.003 U setting when using the Motor Parameter Identification Wizard.
Check if the feedback signal is abnormal. Use the software scope and select
2.
Feedback position [PUU] as the channel type to monitor whether the
feedback value is correct.
Make sure the motor and mechanism can operate properly.
3.
Check if the friction between the motor and mechanism is too large.
4.
If so, increase the set value of PM.011 by 50% at a time for testing.
Check if the moving distance is too large during the initial magnetic field
5.
detection when the motor is powered on. Use the software scope and select
Feedback position [PUU] as the channel type to monitor whether the
feedback value is correct. Try reducing the set value of the initial magnetic
field adsorption of PM.011 when Servo On.
