Performance features

Excellent control performance

1. Closed-loop torque response is below 10ms, steady speed accuracy is 0.02% and speed ripple is 0.2%;
2. Open loop torque response is below 20ms, steady speed accuracy is 0.2% for synchronous motor and 0.5% for the asynchronous motor;
3. Broadband speed regulation features, the maximum output frequency is 1200Hz and the lowest carrier frequency is 1 KHz.

High starting torque characteristics - adapt to the low frequency cutting of the machine tool

High low-frequency torque: In the open-loop vector mode, 150% of the rated torque could be output at 0.5Hz. While in a closed-loop vector mode, 200% of the rated torque could be output at 0Hz.

High starting torque characteristics - adapt to the low frequency cutting of the machine tool

1. Stable high-speed field-weakening control - can adapt to machine overclocking operation and wide-range speed control.
2. The brand-new flux-weakening control algorithm combined with the high-bandwidth current vector algorithm enables stable high-speed field-weakening operation and supports up to 12 times of field-weakening high-precision output.
