Example 1: Operation In Speed Mode With Reference Via Parameter - WEG SCA06 User Manual

Energizing and Start of Operation
1. Control via external device using analog/digital I/Os: program P00202 in 1 or 2 according to application (torque
or speed control).
2. Control via external device using CANopen network: program P00202 in 5 (torque, speed or position control).
3. Control via ladder programming of the SCA06: program P00202 in 4 (torque, speed or position control).
In the first case, it is also necessary to program the parameters referring to the Analog/Digital I/Os according to
the application. In the second case, it is necessary to program the parameters of the CANopen network and, in
the third case, a ladder program made in the personal computer (using the proper WEG software) must be loaded
to the servo drive which will execute the necessary functions for the application.
Even if parameter P00202 is not programmed in option 4, it is possible to execute a ladder program in the SCA06;
however, in this case, the ladder will not control the shaft, but execute other auxiliary functions, such as logic, etc.
By the same token, if the parameter P00202 is not programmed in option 5, the CANopen network can still be
used; it just cannot control the shaft.
The SCA06 has control nets of current (torque and flow), speed and position. The current control net is always
used and its parameterization is necessary to program the model of WEG servomotor in parameter P00385.
Then all the parameters of this net are programmed according to the selected servomotor model. The speed and
position nets may be used or not. If used, it is necessary to program their parameters.
