Output filters

For groups of more than 3 or 4 motors, SEW-EURODRIVE recommends using an HF output filter. An HF output filter is required when the maximum motor cable length (l_max) given in the table is exceeded. This may be the case in large groups (n) or when there are long motor cable lengths connected in parallel (l_total). In this case, it is the voltage drop on the motor cable that limits the maximum motor cable length, not the limit value in the table. The total of the rated motor currents must not exceed the rated through-current of the output filter.
