Features CLOSED CONTROL: The digital stepper motor driver adopts advanced vector current, speed and position closed control algorithm. CURRENT RANGE: This driver static current and dynamic current ratio can be set arbitrarily, in the range of 0‑7A. APPLICABLE MODEL: Motor standard 1000 line high accuracy encoder, can drive 42‑60 full series of two phase hybrid stepper servo motor. SIGNAL: The stepper motor driver uses optocoupler to isolate differential signal input, pulse response frequency. VARIOUS PROTECTION: With overcurrent, overvoltage, overspeed, overheating, tracking error and other protection functions, support for command control mode.
