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 waiting 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.
Torque utilization < p2194
0 Torque utilization > p2194
•
The current torque utilization is greater than the
set torque utilization threshold (p2194).
BO: r2199.11 1
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).
1 |n_act| < p2161
The actual speed value is less than the set
threshold value (p2161).
|n_act| t p2161
0 |n_act| ≥ p2161
The actual speed value is greater than or the same
as the set threshold value (p2161).
BO: r2199.0 2
Note:
The message is parameterized as follows:
p2161 Threshold value
p2150 Hysteresis
Application:
To protect the mechanics, the gear stages are not switched mechanically until the speed is less than the set
threshold value.
1 |n_act| ≤ p2155
The actual speed value is less than or the same as
the set threshold value (p2155).
3 |n_act| v p2155
0 |n_act| > p2155
The actual speed value is greater than the set
threshold value (p2155).
