Brake sequence fault

What does E.MB7 mean?

This brake sequence fault stops the inverter output due to a sequence error occurring during the operation of the brake sequence function (configured by Pr. 278 to Pr. 283). This protective feature is not active in the initial inverter status. It indicates a timing or logical error in the controlled braking process.

Complete Troubleshooting Guide

1. 1

   Review the settings for the brake sequence parameters (Pr. 278 to Pr. 283) and adjust as necessary.

2. 2

   Verify that all wiring related to the brake sequence is correctly connected and secure.
