YKE2608MH-IO Spontaneous Impulse Stepper Drive  YKE2608MH-IO is a high-performance stepper driver based on a new generation of digital control technology. The control mode of the driver is spontaneous pulse speed control. There are 16 segments of speed can be set by 4 DIP switches, and any speed within the range can be set through the upper computer. Three-way photoelectric isolation digital input, the driver supports motor parameter identification and phase memory functions; Its similar servo control principle, unique circuit design, superior software algorithm processing can make the motor running stably at low speed, and accurate current control technology greatly reduces the motor fever.  Performance:  32-bit DSP control, low noise and superior vibration performance Three-way optocoupler isolated digital signal input, compatible with 5V/24V signals, support common cathode and anode connection mode Using the latest resonance suppression algorithm, it has excellent stationarity at medium and low speed With 8 current, 16 speed optional Running current, speed, acceleration and deceleration can be set in the upper computer debugging software The lock current can be set by the upper computer, the default setting current is 50% Small size, volume 151*94*54 (mm³), weight 0.5kg  Application:  YKE2608MH-IO is mainly used for speed controling, loading machine, unloading machine, docking station, logistics transmission, load shifting equipment, electronic equipment Dimensions: YKE2608MH-IO Roted Speed Setting: The / speed 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 RPM 50 150 250 350 450 550 650 750 850 950 5 10 20 30 40 100 SW8 ON ON ON ON ON ON ON ON OFF OFF OFF OFF OFF OFF OFF OFF SW7 ON ON ON ON OFF OFF OFF OFF ON ON ON ON OFF OFF OFF OFF SW6 ON ON OFF OFF ON ON OFF OFF ON ON OFF OFF ON ON OFF OFF SW5 ON OFF ON OFF ON OFF ON OFF ON OFF ON OFF ON OFF ON OFF SW4=OFF Control Mode 2 lN1 lN2 statue invalid invalid locking valid invalid CW invalid valid locking valid valid BW SW4=ON Control Mode 1 lN1 lN2 statue invalid invalid locking valid invalid CW invalid valid BW valid valid locking YKE2608MH-IO Current Setting: RMS Default(2.00) 2.57 3.14 3.71 4.28 4.86 5.43 6.00 Peak Default(2.40) 3.08 3.77 4.45 5.14 5.83 6.52 7.20 SW3 ON ON ON ON OFF OFF OFF OFF SW2 ON ON OFF OFF ON ON OFF OFF SW1 ON OFF ON OFF ON OFF ON OFF Terminal Introduction: Symbol Function Specification PWR Power indicator When power on, the green indicator lights up.  TM Work indicator Pulse signal indicator, when there is continuous pulse input, the green indicator light flashes, otherwise the green indicator light is always on.
