Hva betyr 79 ?
The motor did not come up to speed in the allotted time during an autotune procedure. This indicates the motor or connected load is preventing the autotune from completing successfully, potentially due to high friction or an oversized load.
Vanlige årsaker
- Mechanical system connected to the drive is experiencing a high load.
- Application demanding more torque than the motor can deliver.
- Incorrect motor sizing for the application.
- Faulty coupling or gearbox causing increased drag.
