    This series drives are cost-effective, high performance step drives. The design is based on advanced digital current control technology, and features high torque, low noise, and low vibration. The running current, microstep resolution and other parameters are switch selectable.

Anti-Resonance

Provides better motor performance and higher speeds

    Step motor systems have a natural tendency to resonate at certain speeds.The SR drives automatically calculate the system’s natural frequency and apply damping to the control algorithm. This greatly improves midrange stability, allows higher speeds and greater torque utilization, and also improves settling times.

Microstep Emulation

Improves overall system performance

    With Microstep Emulation, low resolution systems can still provide smooth motion. The drive can take low resolution step pulses and create fine resolution motion.

Torque Ripple Smoothing

Produces smoother motion at low speeds

    All step motors have an inherent low speed torque ripple that can affect the motion profile of the motor. By analyzing this torque ripple the system can apply a negative harmonic to counter this effect. This gives the motor much smoother motion at low speed.

Command Signal Smoothing

Improves smoother system performance

    Command Signal smoothing can soften the effect of immediate changes in velocity and direction, making the motion of the motor less jerky. An added advantage is that it can reduce the wear on mechanical components.

Product Specification

Product overview:

    The HHIMD860H adopts the latest 32-bit DSP digital processing technology. Drive control algorithm uses advanced variable current technology and advanced frequency conversion technology. The driven motors can run with low heating, small noise, smooth movement. Users can set any micro-step within 200~51200 and any current value within the rated current, which can meet the needs of most applications. Thanks to the built-in micro-resolution technology, the effect of high resolution can be achieved and the driven motors can run with much smaller noise, lower heating, smoother movement at low to high speed even under low resolution conditions. Motor auto-identification and parameter auto-configuration technology offers optimum responses with different motors and easy-to-use.

Typical application：

    The HHIMD860H can be used in various kinds of small and medium-sized equipment and machines, such as engraving machines, labeling machines, laser cutters, laser typesetting, plotting instrument, CNC machine, automatic assembly equipment, and so on. Particularly adapt to the applications desired with low noise, high speed.

Power supply selection

    The power supply voltage can work normally between the specified range. The HHIMD860H driver is best to use non-stable voltage DC power supply, or transformer voltage reduction + bridge rectification + capacitance filter.However, it should be noted that the rectified voltage ripple peak shall not exceed the specified maximum voltage.It is recommended that users use DC voltage below the maximum voltage to avoid grid fluctuations exceeding the operating range of the drive voltage.

    If the voltage stable switch power supply is used, the output current range of the switch power supply should be set to the maximum.

 pay attention to:

• Pay attention to the positive and negative power supply do not reverse connect;

• It is best to use a non-stable type of DC power supply;

• When using a non-stable voltage power supply, the power supply current output capacity should be greater than 60% of the set current of the drive;

• When using a non-stable voltage switch power supply, the output current of the power supply shall be greater than or equal to the operating current of the drive;

• To reduce costs, two or three drives can share one power supply, but should ensure sufficient power.

defencive function

short-circuit protection

In case of a alternate short circuit and an overflow inside the drive, the drive red light flashes once and flashes repeatedly in a cycle of 3 seconds.At this point, the fault must be eliminated and reset again.

 overvoltage crowbar

When the input voltage is above AC80V / DC110V, the drive red light flashes twice and repeatedly in a 3 second cycle.The fault must be eliminated and reset again.

undervoltage protection

When the input voltage is below AC20V / DC30V, the drive red light flashes 3 times and repeatedly in a 3 second cycle.The fault must be eliminated and reset again.

Lack of phase protection

When the current is initial, when the motor is phase, the driver red light flashes 5 times and flashes repeatedly in a cycle of 3 seconds.At this point, the fault must be eliminated and reset again.
