Table 9- 18 Description of MELDW (message word)
Bit Meaning
0 Ramp-up/ramp-down completed /
ramp-function generator active
1 Torque utilization < 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).

Function Manual, 10/2008, 6SL3097-4AB10-0BP0
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).
