E36.

Brake Error

Omron · MX2 Series Type V2 Compact Inverter

What does E36. mean?

This error indicates that the inverter cannot verify the ON/OFF status of the external brake within the specified 'Brake Error Detection Time' (b124) after a brake release signal. It occurs when the brake control function (b120 = 01) is enabled, suggesting a problem with the brake itself, its confirmation signal, or incorrect timing settings, potentially leading to unsafe load control.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Verify the wiring of the brake confirmation signal (BOK) to ensure it is correctly connected and signaling status.

  2. 4

    Ensure the Brake Release Current (b126) is sufficient to release the brake, otherwise, the inverter may detect an overload.
