Conical Rotor Motors - ABB ACS800 Firmware Manual

Conical rotor motors

Using the Adaptive Programming (AP), you can create a file for handling brake
control of conical rotor motors that do not have an external brake. With the help of
Adaptive Programming, the conical rotor motors can be used together with the
Crane control program.
For more information, see the Application Guide for Adaptive Program
(3AFE64527274 [English]) and DriveAP User's Manual (3AFE64540998 [English]).
The brake control of conical rotor motors is done by using a high flux level during
start and a lower flux level during stopping.
