and
• The defined tolerance bandwidth (p2164) is
exited.

• The ramp-up procedure is still active once the
speed setpoint has been changed.
0 Ramp-up/ramp-down
completed/ramp-function generator
active
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.
