LP1

Motor phase failure

Lenze · SM29_05 Service Bulletin

What does LP1 mean?

A current-carrying motor phase has failed, or the current limit value is set too low. This monitoring function is only applicable for asynchronous motors and requires the MLP1 function block to be entered in C0465. Loss of a motor phase can cause motor damage.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Switch off monitoring by setting C0597 = 3.

  2. 4

    If the current limit value is set too low, set a higher value via C0599.
