If you do not want to set the positive limit (PL) as one of the digital inputs, make sure
none of the digital inputs DI1 - DI10 are set to positive limit (PL) (make sure that
none of the parameters, P2.010 - P2.017, P2.036, and P2.037, are set to 23).
If the positive limit (PL) function is needed, make sure this DI is on when it is preset
as normally closed (function code: 0x0023), and then set this DI as normally open
(function code: 0x0123).
Check the connection between the motor and servo drive.
Check if the conducting wire is short-circuited. Fix the short circuit and prevent any
metal conductors from being exposed.
