♦Dual-core processor, hardware current loop,16KHz position loop and 16KHz speed loop helps to double the performance, compeared to the last generation.

♦Passed EtherCAT CTT test, SD20-E has better compatibility to work with different brands of PLC or automation controller.

♦Bidirectiona data transmission can reach 100Mbps. The min communication cycle is 250uS.

♦Thanks to the gain autotuning function and model feedforward control, no matter there is gain tuning command or not, it helps customers to easily make gain autotuning, and simple commissioning.
