  • Detailed introduction

        Based on TI's new 32-bit multi-channel DSP processing chip platform, using 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 and high-speed high-moment output, and can be well adapted to most applications of stepping motors.

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

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

Typical applications: engraving machines, marking machines, cutting machines, laser equipment, plotters, CNC machine tools, automatic equipment equipment, etc. 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 subdivision, 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 8 output currents. For the   specific output current setting, please see the driver panel description.

Automatic   half-flow function

Users   can set the drive's automatic half-current function through SW4. Off   indicates that the quiescent current is set to half of the operating current,   and on indicates that the quiescent current is the same as the operating   current. In general use, SW4 should be set to off, so that the heat generated   by the motor and driver can be reduced and the reliability can be improved.   The current is automatically halved approximately 0.4 seconds after the burst   stops.

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;

Motor   interface

A+   and A- are connected to the positive and negative terminals of the A-phase   winding of the stepping motor; B+ and B- are connected to the positive and   negative terminals of the B-phase winding of the stepping motor. When A, B   two-phase windings are exchanged, the motor can be in the opposite direction.

Power   interface

Using   DC power supply, R60 working voltage range is recommended 24-50VDC, voltage   power greater than 150W.


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:   118 * 76 * 33mm, mounting hole spacing 112. Can be horizontal or vertical   installation, but it should be close to the metal cabinet for better cooling
