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 32-bit ARM 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 solution 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.

Drive Function Description

Drive function	Instructions
Command pulse form	The standard LS series driver signal interface is in pulse form and can accept two types of pulse command signals; 1. Pulse & Direction (PUL + DIR); 2. Double Pulse (CW + CCW);
output signal	It can be set to alarm output by parameter, positioning completion output, brake output; default is alarm output and positioning completion output.
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.
External display	The DISPlay interface can be connected to the display for easy setting of parameters and observation of operating conditions.
Wide voltage range on Signal terminal	Pulse, direction and enable signal input interface voltage 5V and 24V separate terminals, simple wiring, strong anti-interference ability
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.
