Hey,
Another question about tension on carpet.
I have to change 4 DC-motors by 4 AC-motors (2,2kW). I ordered an S7-315-2DP CPU and 4 MM440 frequency drives. And an OP7. (and much more, but doesn't matter for this topic)
The first motor is Master. the 3 others have to run 10% faster.
Motor 1 2 and 3 have a tension setting on the Operating Panel (OP7). A tension for the carpet. It is needed for other applications that we do on the Carpet, not important for this topic.
The tension must be set from 0-100%
How should I create tension,
Torque control, or speed control with a torque limit ?
thanks
