Bit Meaning Remarks Parameter
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 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.
BO: r2199.5
1 Torque utilization < p2194
 The current torque utilization is less than the set
torque utilization threshold (p2194),
or
 Ramp-up is not yet complete.
1 Torque utilization < p2194
0 Torque utilization > p2194
 The current torque utilization is greater than the
set torque utilization threshold (p2194).
BO: r2199.11
