Motor overtemperature (C0121)

What does OH7 mean?

The motor temperature, detected via resolver or incremental encoder, has exceeded the threshold set in C0121. This indicates thermal overload from impermissible continuous current, frequent/prolonged acceleration processes, or the C0121 value being set too low.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Enter a higher value in C0121 if the temperature threshold is set too low.

2. 4

   Switch off monitoring by setting C0584 = 3.
