  • Detailed introduction

          Based on the platform of TI's new 32-bit multi-channel DSP processing chip, the magnetic field orientation and high-speed flux-weakening algorithm in the servo driver are designed to achieve excellent performance.

          The built-in vector control design and servo demodulation function of the driver, combined with the feedback of the closed-loop motor encoder, make the stepping servo system have the features of low noise, low heating, no lost steps and higher application speed, and can improve the intelligent equipment system performance in all directions.

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

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

Typical applications: lock screw machine, servo dispensing machine, stripping machine, labeling machine, medical detector, electronic assembly equipment, etc. The application effect is particularly good in a device where the user desires high rotation speed and high torque.

Operating   Instructions

Microstep   subdivision setting

SW1-SW4   four dial codes are used to select a total of 16 files of microsteps. When   the user sets the mirco step, electric motion should be stopped first. For   detailed microstep subdivision settings, please see the drive panel   description. Other mirco step can be set through the debug software.

Running   direction setting

SW5   is used to select the initial direction of rotation of the motor. It is   necessary to power off and restarts the drive to make effect.

Pulse   mode selection

SW6   is used to select the input pulse mode, off is the pulse & direction, and   on is CW/CCW pulse. It can also be modified to quadrature pulses by the debug   software. It is necessary to power off and restart the drive to make effect.

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 ends of alarm output signals. PEND+ and PEND-   are the positive and negative ends of the in-position output signal

Encoder   interface

E8+   and E8- are encoder B direction signals; EA+ and EA- are encoder A direction   signals; VCC and GND are encoder power interfaces.

Motor   interface

A+,   A-, B+, B- are the stepping servo motor winding interfaces, which must be   linked with the motor identification color and cannot be exchanged.

Power   interface

AC   and AC are universal inputs for AC and DC power supplies. 2LS860operating voltage   range 18-80VAC or 24-100VDC, voltage power greater than 200W.


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:   151 * 97 * 52mm, mounting hole spacing 142. Can be horizontal or vertical   installation, but it should be close to the metal cabinet for better cooling

LS series closed loop stepping introduction

          The closed-loop stepping drive of Bergerda is based on an ordinary open-loop stepping motor combined with position feedback and servo algorithm to form a high-speed, high-torque, high-precision, low-vibration, low-heat, No-lose-step stepping scheme. LS series stepping servo driver, based on the platform of IT company's new 32-bit DSP processing chip, utilizes magnetic field orientation (FOC) and weak magnetic control algorithm design in servo driver, and has all-round performance beyond ordinary stepping.

Built-in PID parameter adjustment function enables the motor to better meet the application of different types of loads.

Built-in field weakening control algorithm reduces the magnetic field characteristics of the motor at high speed and maintains power.

Built-in current vector control function makes the motor have servo current characteristics and low heat generation.

Built-in micro-step instruction algorithm, so that the motor speed stage to maintain stable, low vibration.

Built-in 4000pulse resolution encoder feedback, so that the motor accuracy, never lost step.

          The servo control direction combined with the characteristics of the stepping motor enables the LS series closed-loop stepping driver to better perform the performance of the stepping motor and replace the same power servo application, making the automation equipment the most cost-effective new choice.

          Application: It is especially good for users who want small noise and high speed equipment. For example: engraving machine, stripping machine, marking machine, cutting machine, solid crystal machine, plotter, CNC machine tools, automatic assembly equipment.

Command pulse form

The   standard LS series driver signal interface is in pulse form and can accept   three types of pulse command signals;

1.   Pulse & Direction (PUL + DIR); 2. Double Pulse (CW + CCW); 3. Quadrature   Pulse (A/B Quadrature Pulse)

Alarm Output

The   alarm output port ALM is used to output the drive operation status to the   external control circuit. When the driver is in the error state and normal   operating state, ALM outputs different optocoupler levels. Alarm signals can   be reused as in-position signals.

Control algorithm is   optional

The   leading space vector servo control algorithm and the traditional advance   angle control algorithm are optional, and the user can arbitrarily select   according to the occasion.

The highest pulse   frequency is optional

With   the highest pulse frequency of 200K and 1MHZ as standard, optional debugging   software can modify any maximum pulse frequency within 1M.

Wide voltage range on   Signal terminal

The   pulse, direction, and enable signal input interface voltages are 3.3 to 24V   compatible, eliminating the need for a series limiting resistor.

Seven status LED   displays

The   LS series driver has two operating states and five fault LED indication   functions, allowing the user to clearly confirm the status of the driver.
