1、△method: (A+、B-)----phase, (B+、C-)----phase, (C+、A-)----phase, is set to be U,V, W each. The driven current set to be √3 times of phase current. For example: the phase current of J31115 is 3.5A, the current of drive should be set to√3×3.5＝6A.

2、Y method: A-、B-、C- are parallel connection and A+、B+、C+ is U、V、W phase each. The current of drive should be set to be equal to phase current of motor. For example: the phase current of J31115 is 3.5A, the current of drive is 3.5A.
