Please check if any of the digital inputs DI1–DI10 are set to positive limit (PL) and that DI is
on.
Corrective action:
1. If you do not want to set the positive limit (PL) as one of the digital inputs, make sure
no other digital input is set to positive limit (PL) for DI1 – DI10 (make sure that none of
the parameters, P2.010 – P2.017, P2.036, and P2.037 is set to 23).

code: 0x0023), please make sure DI is always normally closed. If not, please set DI as
normally open (function code: 0x0123).
