Limitation Of The Speed By Fixed Frequencies; Temperature Adjustment - BONFIGLIOLI ACTIVE Applications Manual

5.3
The maximum permitted speed can be limited by the parameters
480,
For this, the parameter
tion mode 110.
If the additional limitation has been activated, the maximum frequency (maybe per-
mitted by the load detection or its modification during the movement of a luffing jib) is
limited to the current fixed frequency. The limitation is effective for both clockwise
and anti-clockwise.
5.4
The properties of the asynchronous machine change with the temperature and can be
taken into account via a suitable measurement or estimate. Various methods and
sources of actual values for temperature detection are to be selected via the parame-
ter
The parameter
tion mode 4-temperature estimate in the configurations 260 and 460. In switching on,
the temperature of the asynchronous machine is estimated and taken into account for
correct calculation.
If this is not required, the parameter
must be parameterized to the operation mode 0-Off.

out via the actual value parameter
