12.5.9 0x6048/n Velocity acceleration
Highest sub-index supported
• Motion Control:
o Velocity mode
• Non motion Control (conf. ≠ x40)
• Motion Control:
o Table Travel record mode
o Profile Positioning mode
o Profile Velocity mode
o Homing mode
o Interpolated mode
o Move away from Limit Switch
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 Ac-
celeration (clockwise) 420 and Acceleration (anti-clockwise) 422
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, ta
k-
ing 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
(object 0x1010
) processed, the object values are stored in non volatile memory. After
the next power on of the inverter, the previously set values are reactivated and ove
