New structural appearance design, compact and space-saving.

3kHz speed loop response bandwidth

Through the unique current loop algorithm, the bandwidth of the speed loop is effectively increased, and the setting time is greatly shortened. The fastest setting time can reach 1ms, which improves production efficiency.

23-Bit absolute encoder

Standard 23-Bit multi-turn absolute encoder, single-turn up to 8388608 pulses, communication speed up to 2.5Mpps.
The positioning is more accurate, the low speed is more stable, and the power-off position is not lost.

Robust control

The new control theory algorithm is adopted to realize that even if the load moment of inertia changes within 30 times during the movement, there is no need to set the slave parameters to ensure smooth operation.
It can be used after installation. This function is widely used in manipulators.
