AHD802X, AHD812X and AHD822X use high speed motion control CPU to realize bipolar constant current chopper sine wave micro step driving based on fast adaptive predictive control. The driver has characteristic of high precision, high torque, low noise, wide speed. The driver has functions of self test, fault detection, status indication, and protection.
Driver supports 2-phase stepping motor of 4-line, 6-line and 8-line. Motor should be connectted 4-line or equal to 4-line structure when use. This driver doesn't support 3-phase and 5-phase motors.
Suggest to QEP interface if design a new motion control system. Because the QEP is better than other interfaces at step pulse frequency and immunity characteristic.
