Application Development Kit v6.5 software from ACS Motion Control supports the firm's motion control products including the SPiiPlus 3U-HP, SPiiPlus LF, MC4U, and LDM 3U linear drive. The software also provides EnDat and Smart-Abs absolute encoder support through the HSSI-HES extension card. It features two-phase step motor support in open-loop or true closed-loop control as well as two-phase DC brushless motor support in closed loop. It also supports CANopen-certified servo drives and I/O modules. The tool includes additional bi-quad filters, disturbance rejection algorithm, and extended analog outputs. Simulation and motion machine interface tools are incorporated to minimize setup, tuning, and programming time for motion control applications.
