Function Manual, 01/2011, 6SL3097-4AB10-0BP3
Remarks
1 Ramp-up/ramp-down completed.
The ramp-up procedure is completed once the

speed setpoint has been changed.
1/0 Ramp-up starts.
The start of the ramp-up procedure is detected as
follows:
The speed setpoint changes,

and
The defined tolerance bandwidth (p2164) is

exited.
0 Ramp-function generator active
The ramp-up procedure is still active once the

speed setpoint has been changed.
0/1 Ramp-up ends.
The end of the ramp-up procedure is detected as
follows:
The speed setpoint is constant,

and
The actual speed value is within the tolerance

bandwidth and has reached the speed setpoint,
and
The delay time (p2166) has elapsed.

1 Torque utilization < p2194
The current torque utilization is less than the set

torque utilization threshold (p2194),
or
Ramp-up is not yet complete.

0 Torque utilization > p2194
The current torque utilization is greater than the

set torque utilization threshold (p2194).
