5.16 Interface Parallel Configuration
The Drives can be used in a parallel configuration in the PWM driven modes as well as in analog driven
modes and also in the combines analog / PWM mode in such a way that the control lines are connected in
parallel as shown in below for the example of two Drives.
There is no limitation from the Drive‘s point of view in paralleling them. Nevertheless from the CCU’s point of
view it has to be considered that all of the Drives needs a certain current each on the signal lines PWM* / E*
and A. This has to be taken into account for dimensioning the driver stage which controls digitally via the
PWM* / E* inputs of the Drives or which controls analog via the A inputs of the Drives. The output driver
stage of the CCU needs to be capable of driving minimum the input currents of PWM* / E* and / or A times
the number of the Drives.
