OH8

Motor overtemperature (T1/T2)

Lenze · 9300 Series

Was bedeutet OH8 ?

The motor temperature, measured via inputs T1 and T2, is too high. This signifies thermal overload due to impermissible continuous current or frequent/prolonged acceleration processes. It can also occur if terminals T1 and T2 are not connected to a PTC/temperature contact.

Häufige Ursachen

  • Motor temperature sensor (T1/T2) indicates an overtemperature condition.
  • Excessive motor current draw causing rapid temperature rise.
  • External motor cooling system failure.
  • Poor thermal contact between sensor and motor windings.

  1. 1

    Check drive dimensioning to ensure the motor is not continuously overloaded.

  2. 2

    Connect the PTC/temperature contact if terminals T1 and T2 are not connected.

  3. 3

    Switch off monitoring by setting C0585 = 3.
