Acceleration pause
133
Acceleration pause
With this function, you can specify a pause in the acceleration
ramp, during which the output frequency remains constant. If the
frequency inverter is overloaded during acceleration, for example
when accelerating heavy loads or when starting motors in reverse,
you can use this function to define a rest period in which no acce-
leration takes place to prevent frequency inverter overload. Under
PNU A069, specify the frequency at which the pause is to start.
PNU A070 determines the duration of the pause.
With motors running in reverse, this function keeps the output
voltage and output frequency low until the motor has stopped and
is running in the required direction before accelerating at the
specified acceleration ramp.
