Rated for 100–220V AC input at 50\/60Hz with 2.8A maximum phase current, this new unit features a finned aluminum heatsink for thermal dissipation and includes green 3-pin terminal blocks for motor and control signal connections. The device incorporates control inputs for clockwise\/counterclockwise rotation, hold\/off function, divisor selection, and zero-output command, with status indication via Power, Alarm, Run, and Test LED indicators. Operating specifications include support for step division (1×, 2×, 4×, 8× configurable via MS1\/MS2 selector), CW\/CCW directional control, and manual step pulse input via the TEST button for diagnostic purposes. This controller is commonly used in precision positioning, light industrial automation, CNC retrofits, and micro-motion applications requiring reliable five-phase stepper operation.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct
