8.5.6 0x6048/n Velocity acceleration
The alteration of the speed and run-up time are set with the object velocity
acceleration. The object velocity acceleration defines the value delta speed via
subindex 1 in the same notation (RPM) as the ob
ect tar
et velocity and the value
delta time in seconds via subindex 2.
Velocity acceleration
Index Subindex Meaning Value
0x6048 0 Number of entries (unsigned 8) 2
1 Delta speed (RPM) (unsigned 32)
2 Delta time (sec) (unsigned 16)
The gradient of the frequency in the acceleration period is written onto the
parameters
Acceleration (clockwise) 420 and Acceleration (anti-clockwise) 422 in
the first data set inside the product. The two parameters are set to the same value,
which is specified via the object velocity acceleration.
The gradient is changed internally by alterin
the ob
ects delta time or delta speed.
Chan
in
the ob
ect value for delta speed, which is internally converted into the uni
Hz, is sufficient for a change of the gradient.
Parameter Setting
No. Object Min. Max.
0x6048/1 Delta speed (RPM) 1 65536
0x6048/2 Delta time (sec) 1 65535

Note:
he ob
ect delta time is always set to the ob
ect value = 1 after the rese
of the frequency inverter.
