Procedure for connecting an uncontrolled motor:
1. The speed-controlled motor turns with maximum speed p1082.
2. The control deviation of the technology controller is greater than p2373.
3. Time p2374 has expired.
The converter brakes the speed-controlled motor with ramp-down time p1121 to the
activation/deactivation speed p2378. Until the activation/deactivation speed p2378 is
attained, the converter deactivates the technology controller temporarily.
4. After switch-on delay p2384, the converter connects an uncontrolled motor.
