The acceleration in velocity mode is set with object
velocity acceleration. The object
velocity acceleration consists of delta speed in RPM and delta time in seconds.
The gradient of the frequency in the acceleration period is written to parameters
Accel-
eration (clockwise)
420 and
Acceleration (anti-clockwise)
422 (data set 5, all data
sets in RAM only !). Both parameters are set to the same value.
The values of p.420 and p.422 are converted internally to a frequency/sec value, taking
into account parameter
No. of Pole Pairs
373 (in data set 1 !).
The gradient is changed internally by altering the objects delta time or delta speed.

If objects 0x6048/1 or 0x6048/2 were written and then a save parameters command

the next power on of the inverter, the previously set values are reactivated and over-
