MAXPOS 50/5 Positioning Controller

Thanks to the latest FPGA (Field Programmable Gate Array) technology, highest control cycle rates can be achieved with minimally short cycle times at the same time for brushed DC and brushless EC (BLDC) motors up to 250 Watt. Sophisticated motion control tasks with a current controller clock speed of 100 kHz and an effective communication cycle time of 100 μs can be achieved with a suitable EtherCAT master for trajectory planning. This unveils unprecedented possibilities as far as presicion, dynamics and synchronization are concerned.
