Why RB Automation

Servo Driver Supplier in India

Stock, sizing help and after-sales support behind every AC Servo Drives we ship.

A servo driver, also called a servo drive, closes the loop between the controller and the servo motor. RB Automation is a servo driver supplier in India with the R5, R6, RS, S5L and S6L series up to 3 kW, with EtherCAT or RS485 control and matching RSDA, RSHA and RSNA servo motors.

Each drive takes pulse, RS485 or EtherCAT commands from a PLC or motion controller. It then controls motor position, speed or torque from encoder feedback. The range splits into two groups. The R5 and R6 are high-performance drives with STO safety. The S5L and S6L are cost-effective drives for general machine automation.

  • R5 Series: 5th generation, 0.05 to 2.3 kW, auto-tuning, rich I/O and high dynamic response. Uses SVPWM drive mode with absolute encoder feedback, set up from the drive buttons or RTServoStudioV5 software.
  • R6 Series: 6th generation, 0.1 to 3 kW, ARM+FPGA control with R-AI 2.0. M versions are pulse type with RS485; E versions run under an EtherCAT master.
  • S5L Series: 5th generation, 50 W to 2000 W, RS485 Modbus networking and built-in PLC programming.
  • S6L Series: 6th generation, 100 W to 2000 W, RS485 Modbus networking and absolute encoder support.
  • Control modes: position, speed and torque control across the S5L and S6L series.
  • Supply: R6 drives run on 220 VAC ±10%, 50/60 Hz, single phase or three phase depending on rating.

These drives go into packaging, textile, CNC and robotic machines. Machines driven by PLC pulse or RS485 commands fit the S5L, S6L or R6 M versions. Multi-axis machines on an EtherCAT master, such as the RM500/510 motion controller, fit the R6 E versions. Each drive is supplied with matching RSDA, RSHA or RSNA motors and cables, listed on the AC servo motor page. Standardising on one series across a machine line keeps programming and spares simple.

RB Automation helps pick the series by motor power, communication and control features. The team sizes the motor against load and duty, matches drive, motor and cable, and supports wiring and tuning. Send your axis count, controller type and quantity for a quote.

FAQs

AC Servo Drive FAQs

Straight answers to what buyers ask us most about AC Servo Drives.

RB Automation offers four AC servo drive series: R5, R6, S5L and S6L. The R5 and R6 are high-performance drives, with the R6 adding ARM+FPGA architecture, R-AI 2.0 and EtherCAT or RS485 communication. The S5L and S6L are cost-effective series with RS485 Modbus networking and position, speed and torque control for general machine automation.

The R5 covers 0.05-2.3 kW, the R6 covers 0.1-3 kW, the S5L covers 50 W-2000 W and the S6L covers 100 W-2000 W. Both R series drives include STO safety, while the S6L supports an absolute encoder and the S5L adds built-in PLC programming. Choose the series by motor power, communication and the control features your machine needs.

For EtherCAT networks, choose the R6 Series, the drive on this page that lists EtherCAT alongside RS485, with 6th-generation ARM+FPGA control and R-AI 2.0. For RS485 Modbus networking at lower cost, the S5L or S6L series fit, and the R5 suits machines needing auto-tuning, rich I/O and high dynamic response. RB Automation can confirm the choice for your controller.

AC servo drive price depends on the series (R5, R6, S5L or S6L), power rating, communication interface, whether a matching motor and cables are included, and order quantity. RB Automation provides a quotation for your exact drive and motor combination rather than a fixed list price. Call +91 8511104864 or use the Inquiry button on the drive you need.

You can buy R5, R6, S5L and S6L AC servo drives from RB Automation in Ahmedabad, Gujarat, which supplies OEMs and machine builders across India.
