  • Detailed introduction

          Based on TI's new 32-bit DSP processing chip platform, the internal PID current control algorithm design, with excellent performance. The built-in micro-segmentation technology and the automatic tuning function of the power-on parameter make the driver have the characteristics of low noise, low vibration, low heat generation and high-speed high torque output. In addition, the patented three-phase demodulation algorithm can give full play to the low-speed resonance and small torque ripple characteristics of the phase stepping motor, and can be well adapted to applications requiring higher stability.

Pulse mode: single pulse/ CW/CCW pulse/quadrature pulse

Signal level: 3.3-24V compatible, PLC applications without string resistance.

Typical applications: potting machines, engraving machines, cutting machines, laser equipment, CNC machine tools, automatic equipment and so on. The application effect is particularly good in a device where the user desires high speed and small noise.


Drive function description

Drive   function

Operating   Instructions

Microstep   subdivision setting

SW5-SW8   four dial codes are used to select a total of 16 files of microsteps. When   the user sets the mirco step, driver should be stopped first. For detailed   microstep subdivision settings, please see the drive panel description.

Output   current setting

SW1-SW3   three dial switches are used to select a total of 16 output currents. For the   specific output current setting, please see the driver panel description.

Pulse   smoothing and bandwidth selection

The   SW9 dial code is used to select the pulse smoothing function of the driver.   Off means turn this feature off, on means turn this feature on. SW0 is used   to select the bandwidth of the driver. The maximum pass pulse frequency is   200KHZ when off, and the maximum pass pulse frequency is 1MHZ when on.

Signal   interface

PUL+   and PUL- are the positive and negative ends of the control pulse signal; DIR+   and DIR- are the positive and negative ends of the direction signal; ENA+ and   ENA- are the positive and negative ends of the enable signal; ALM+ and ALM-   are the positive and negative terminals of the alarm output signal; RDY+ and   RDY- are the positive and negative terminals of the in-position signal.

Motor   interface

U,   V, W butt the motor windings U, V, W, Arbitrarily swapping two of the three   winding wires can change the direction of the motor., PE ground wire.

Power   interface

The   working voltage range is recommended for AC 110-230V. It is recommended to   add a filter (EMI FILTER) before the power supply circuit.


The   driver has two indicators, red and green. The green light is the power   indicator. The green light flashes after the driver is powered on. The red   light is the fault indicator. The red light flickers when there is a fault in   the gear and the encoder is misaligned. After the fault is cleared, the red   light goes out. When an alarm occurs on the drive, it must be powered on   again to clear the fault.

Installation   Notes

Dimensions:   203 * 147 * 78mm, mounting hole spacing 193. Can be horizontal or vertical   installation, but it should be close to the metal cabinet for better cooling
