E2061 Device overload prewarning
For HCS, HMS, HMD
For HMV01.1R
Cause
Incorrect value of P-0-0441, Overload warning
Overload of drive (e.g. due to too high infeed during
machining or too high acceleration to high speed)
Changes in mechanical system with regard to friction
and moved masses
DOK-INDRV*-GEN-**VRS**-WA01-EN-P

Supported by Supply Unit:
The work load of the device has exceeded a threshold and a message is
generated that warns against overload which will occur if the load is not
reduced.
Devices with digital control are monitored by means of a permanently
processed temperature model. If the thermal work load approaches
100 % the continuous current limit is activated shortly after and the
warning E8057 Device overload, current limit active appears.
When the current is limited the torque/force is reduced which is not
wanted for machines and installations and can cause problems. A
warning is therefore output before this situation occurs.
The threshold value for the overload prewarning can be set in P-0-0441,
Overload warning. If the thermal work load exceeds this value the
E2061 warning is output. Useful values for P-0-0441, Overload warning
are at 80-90% so that there still is a little reserve capacity until the actual
thermal work load is reached (100%).
Note:
The warning can be deactivated by the value "100%" in
P-0-0441, Overload warning because in this case the fatal
warning E8057 Device overload, current limit active
warning is immediately generated!
The threshold value for the overload prewarning is fixed to 90%. If the
thermal work load exceeds this value the E2061 warning is output. This
threshold cannot be set and therefore the warning cannot be deactivated!
Remedy
Increase value of P-0-0441, Overload warning, if
necessary
Switch drive off and let it cool down. Check drive
dimensioning and command value profile
In the case of installations that have been run for a long
time, check drive conditions for changes in mechanical
system
