Other motor parameters configured according to motor manufacturer specs. To test configuration, set drive in torque mode and try motor with different torque setpoints (Granity testing tab). If motor produces force over it's travel distance, the settings are correct. If motor locks at some position, invert FBI. | Other motor parameters configured according to motor manufacturer specs.
