Cycle power on the servo drive.
Condition:
After the initial magnetic field detection is complete, the servo system then
1.
attempts, but fails to reduce the existing position error.
If the controller issues commands when the servo system is not fully settled,
2.
the position error might thus be greater and cannot be reduced.
Cause: the controller issues commands during initial magnetic field detection.
Check if the controller has issued a command immediately when it is powered
1.
on. Use the software scope and select "Command Position [PUU]" as the
input signal for the channel to monitor whether there is a command issued. If
so, increase the delay time for the controller to issue the command after it is
powered on.
If the controller time sequence cannot be modified due to surge interference or
2.
other factors when the power is on, set P2.088 [Bit 4] to 1 to prohibit the servo
from receiving controller commands during the initial magnetic field detection.

Condition: incorrect setting of PM.000.
Cause:
A Delta motor is connected to CN2 as the main encoder, but PM.000 is not set
1.
to 0.
A Delta motor with magnetic encoder is used, but PM.000 or PM.003 is set
2.
incorrectly.
Check the setting of PM.000.
1.
Make sure the type of motor used complies with the setting of PM.000.
2.
If a Delta motor with magnetic encoder is used, set PM.000 to 0 and PM.003
