Key Takeaways
- RB Automation supplies Rtelligent R5, R6, RS, S5L and S6L AC servo drives to Chennai from its Ahmedabad base.
- The R6 offers STO and EtherCAT, Profinet, CANopen or Modbus options, so it can follow the network standard of a line.
- Choose the drive by matched motor, supply, control mode and the I/O the station needs.
- Earthing, shielded encoder cables and proper gain tuning decide how well a servo axis performs.
On the pick-and-place and indexing axes of a Sriperumbudur or Oragadam supplier line, the servo drive decides how quickly the axis settles, how it reacts when a part jams and how much the maintenance team can see when something goes wrong. For machine builders and plant engineers looking for a servo drive supplier in Chennai, RB Automation supplies the Rtelligent AC servo drive range from Ahmedabad, matched to the motor and controller.
Servo Drives in Chennai Industry
Tier suppliers in Sriperumbudur, Oragadam, Irungattukottai and Maraimalai Nagar run servo drives on indexing tables, pick-and-place units, press-fit and screw-driving stations. Engineering units in Ambattur and Guindy use them on press feeders and special machines. Packaging and electronics machinery along the corridor uses them for synchronised film, web and product handling. In each case, clean earthing, shielded encoder cables routed away from power wiring and a proper tuning session separate a smooth axis from one that throws nuisance alarms.
Inside a Servo Drive
A servo drive runs three nested loops. The current loop controls torque, the speed loop holds velocity and the position loop makes the axis follow its command. The command may arrive as pulses, as an analogue reference or as a network message. The drive reads the motor encoder continuously, and its gain settings determine whether the axis feels soft or stiff. It also protects the motor against overload, overspeed and encoder faults.
Matching the Drive to the Line's Network
Large automotive plants and their suppliers tend to standardise on one fieldbus across a line, and a new machine is expected to fit it. That is where the choice of drive matters:
- Pulse and direction suits one to a few axes on a PLC with fast pulse outputs, such as the RX3U.
- Analogue speed or torque references suit tension, winding and press-force control.
- Modbus over RS-485, available on the S5L and S6L, lets a PLC read status and change parameters.
- EtherCAT, Profinet or CANopen on the R6 suit multi-axis machines run by a motion controller such as the RM500, or a line that already uses one of these networks.
Checklist for Choosing a Servo Drive
- Start with the motor: the drive must match its power and encoder.
- Confirm the supply available in the panel.
- Pick the command interface your controller and line standard require.
- List the I/O: limit switches, home sensor, brake output, alarm, and an STO circuit if the machine safety design calls for one.
- Plan for regeneration on fast-stopping or vertical axes, which may need a braking resistor.

See the AC servo drive page, and pick the matching motor from our Chennai servo motor guide.
Replacing an Ageing Drive
Repeated over-current or encoder alarms, overheating, or a model that can no longer be sourced are the usual reasons to change. The article signs it's time to replace your AC servo drive lists what to look for. When the motor is also old, replacing both as a matched pair is often simpler.
A Typical Servo Drive Application in Chennai
Consider a typical rotary indexing assembly machine built for a tier supplier near Sriperumbudur. A servo indexes the dial, a two-axis pick-and-place loads parts and a third axis presses them home. If the customer's line runs on EtherCAT, R6 drives with EtherCAT under an RM500 motion controller let the program coordinate all axes, read torque during the press step and display the faulted axis on the HMI. The STO input lets the guard door circuit remove motor torque without cutting drive power, so the machine restarts faster after an operator intervention.
Picking the Command Interface
| Interface | What it needs | When to use it |
|---|---|---|
| Pulse and direction | Fast pulse outputs on the PLC | One to a few axes on a compact machine |
| Analogue reference | Speed or torque signal | Tension, winding and force control |
| Modbus RS-485 | Serial port on PLC or HMI | Parameter changes and status reading |
| EtherCAT, Profinet or CANopen | Matching master or motion controller | Synchronised axes and line-standard networks |
Servo Drive Series Compared
| Series | Command options | Typical role |
|---|---|---|
| R6 | Pulse, analogue, EtherCAT, Profinet, CANopen or Modbus options; STO | Networked multi-axis machines and lines with a set fieldbus |
| R5 | General purpose interface | Standard single machine axes |
| RS | AC servo drive range | General machine duty |
| S5L | RS-485 Modbus; position, speed and torque modes | Motors from 50 W to 2000 W |
| S6L | RS-485 Modbus; position, speed and torque modes | Motors from 100 W to 2 kW |
Power ratings and interfaces vary by model; each product page lists them, and we confirm the motor and drive pair before quoting.

Common Servo Drive Mistakes to Avoid
- Leaving gains at factory defaults on a heavy or high-inertia load.
- Weak earthing and unshielded encoder cables near welding or press equipment.
- No braking resistor on axes that stop hard or carry vertical loads.
- Choosing a fieldbus option that does not match the customer's line standard.
- Not wiring limit and home sensors before the first test run.

Frequently Asked Questions
Which servo drives do you supply to Chennai?
We supply Rtelligent R5, R6 and RS series AC servo drives and the S5L and S6L series, together with matched servo motors, all shipped from Ahmedabad.
Do your servo drives support EtherCAT or Profinet?
The R6 series is available with EtherCAT, Profinet, CANopen or Modbus options. The S5L and S6L offer RS-485 Modbus. Tell us your controller and line standard and we will confirm the right version.
Does the R6 servo drive have safe torque off?
Yes. The R6 series includes an STO (safe torque off) function. The safety circuit around it should be designed to your machine's own risk assessment.
Can I run a servo drive from my existing PLC?
Usually yes. A PLC with high-speed pulse outputs can command a drive in pulse mode, and a fieldbus PLC or motion controller can use a networked drive. Share the PLC model and we will check.
What is the price of a servo drive in Chennai?
The price depends on the drive series, power, communication option, matching motor and quantity, so there is no fixed price list. Use the form on this page, call +91 8511104864 or email contact@rbautomate.com.
