01/02 AWB8230-1413GB Acceleration pauseAcceleration pauseWith this function, you can specify a pause in the accelerationramp, during which the output frequency remains constant. Whenthe frequency inverter is overloaded during acceleration, forexample when accelerating heavy loads or when starting motorsin reverse, set an acceleration pause with this function. Thisprevents a frequency inverter overload. Under PNU A069, specifythe frequency at which the pause is to start. PNU A070 determinesthe duration of the pause.With motors running in reverse, this function keeps the outputvoltage <strong>and</strong> output frequency low until the motor has stopped <strong>and</strong>is running in the required direction before accelerating at thespecified acceleration ramp.f of sPNU A069PNU A070Figure 114: Function chart for acceleration waiting timef o : Output frequencyf s : <strong>Frequency</strong> setpoint valuetPNU Name Adjustable in RUN mode Value Function WENormal ExtendedA069 Waiting time frequency – j 0 to 400 Hz When this frequency is reached, the pause begins. 0.00A070 Waiting time 0 to 60 s Setting the waiting time. 0.0115
