4 Description 2 Description This example describes how it is possible to limit the operating range of a motor potentiometer (MOP). It is assumed that the drive system has already been basically commissioned (drive inverter, motor and open-loop control). Additional information regarding the commissioning and MOP is provided in the parameter list and the Instruction Manual. In this particular example we are assuming that the motor potentiometer must operate between two fixed limits; the lower limit, fmin = 20Hz and the upper limit, fmax = 50Hz. Depending on the ramp times, the response behavior of the MOP is either fast or slow. In order to speed-up the response characteristics of the MOP, in this example, the drive inverter limit fmax (54 Hz) is set somewhat higher than the MOP limit fmax. As shown in the block diagram (Fig. 5.1), BICO technology and free blocks are used to implement this example. The parameterization described in the following is sufficient in order to implement the function to limit the MOP operating range. The system can either be parameterized using the BOP or AOP operator panels or also using the STARTER commissioning tool. A&D SD Page 4/16
