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:
S The speed setpoint changes
and
S The defined tolerance bandwidth (p2164) is
exited.
0
Ramp-up/ramp-down
completed / ramp-function
generator active
0 Ramp-function generator active
The ramp-up procedure is still active once the
speed setpoint has been changed.
BO:
r2199.5
0/1 Ramp-up procedure completed
The ramp-up procedure is complete when:
S The speed setpoint is constant
and
S The actual speed value is within the tolerance
bandwidth and has reached the speed
setpoint
and
S The waiting time (p2166) has elapsed.
Torque utilization < p2194
1 Torque utilization < p2194
The current torque utilization is less than the set
torque utilization threshold (p2194).
or
Ramp-up is not yet complete.
BO:
r2199.11
1 0 Torque utilization > p2194
The current torque utilization is greater than the
set torque utilization threshold (p2194).
Application:
This message indicates that the motor is overloaded and appropriate measures need to be taken
to rectify the situation (e.g. stop the motor or reduce the load).
