Servo Drive Supplier in Bengaluru: Buying Guide

Key Takeaways

R6 and S6L servo drives suit the robotic cells and precision stages built around Peenya and the electronics estates.
We supply Rtelligent R5, R6, S5L and S6L AC servo drives to Bengaluru from Ahmedabad.
Choose the interface first: pulse, analogue, Modbus RS-485 or a fieldbus such as EtherCAT.
Earthing, shielded encoder cables and proper gain tuning decide how well the axis performs.

Much of Bengaluru's automation work is integration: robotic cells, precision stages, assembly and test machines that combine several servo axes with a motion controller, vision and safety systems. In that environment the servo drive is chosen as much for its network and safety features as for its power. As a servo drive supplier in Bengaluru, RB Automation dispatches Rtelligent drives, paired with their motors, from Ahmedabad and supports selection by phone, WhatsApp and email.

Inside a Servo Drive

The drive runs three nested control loops: current, speed and position. It takes a command from the controller, reads the motor encoder and regulates current so the shaft follows the profile even as the load changes. Gain settings set the axis character; poorly tuned gains show up as overshoot, hunting or noise. Network drives also report status, alarms and actual position back to the controller.

Rtelligent Servo Drives for Bengaluru

R6 series: ARM plus FPGA platform with the R-AI 2.0 tuning algorithm, STO (safe torque off), analogue control and EtherCAT, Profinet, CANopen or Modbus options. The natural fit for multi-axis robotic cells.
R5 series: general-purpose AC servo drives for single and few-axis machines.
S6L series: for 100 W to 2 kW motors, with RS-485 Modbus networking, position, speed and torque control and 3x overload.
S5L series: for 50 W to 2000 W motors, with RS-485 Modbus, position, speed and torque control and 3x overload.

The AC servo drive category page has the details; motors to pair with them are covered in the Bengaluru servo motor guide.

Picking the Command Interface

Pulse and direction

The easiest hook-up when the PLC has fast transistor outputs, for example the Rtelligent RX8U with 8-axis pulse output. Good for a handful of axes on an SPM or test fixture.

Analogue reference

A voltage that sets velocity or torque, still common in tension, winding and force control.

Modbus RS-485

The S5L and S6L can be parameterised and monitored over Modbus, handy when an HMI should show drive status.

Fieldbus

EtherCAT, Profinet or CANopen on the R6 lets one cable carry commands, feedback and diagnostics. With an EtherCAT motion controller such as the RM500, programmed in CODESYS 3.5, axes can be synchronised for interpolated motion.

Bengaluru Applications

Robotic cells and precision stages around Peenya: R6 drives on EtherCAT give integrators synchronised axes and STO for the safety circuit.

Electronics and lab equipment in Electronic City and Whitefield: S6L drives with Modbus monitoring suit dispensing, inspection and handling stations.

Automotive assembly at Bidadi, Narasapura and Attibele: servo drives run press-fit, screwdriving and test axes where force or torque must be controlled.

CNC retrofits in Bommasandra and Jigani: drives are replaced when the original model is no longer available or keeps tripping. Overheating, repeated encoder faults and missing spares are covered in our article on when an AC servo drive is due for replacement.

Selection Steps

Fix the motor first; the drive must be the matched rating and encoder type.
Confirm supply: single-phase or three-phase AC.
Choose the interface your controller uses.
List the I/O: limits, home sensor, brake output, alarm and STO wiring.
Check regeneration on fast-stopping or vertical axes and add a braking resistor if needed.

Servo Drive Series at a Glance

Series	Communication	Notable features	Typical Bengaluru role
R6	EtherCAT, Profinet, CANopen or Modbus options	ARM+FPGA, R-AI 2.0 tuning, STO	Multi-axis robotic cells
R5	Varies by model	General-purpose AC servo drive	Single and few-axis machines
S6L	RS-485 Modbus	100 W to 2 kW, 3x overload	Electronics handling and dispensing
S5L	RS-485 Modbus	50 W to 2000 W, 3x overload	Compact machines and test stations

Interface Choice in Practice

Interface	What you wire	Use it when
Step/direction	Two fast PLC outputs per axis	A few axes on an SPM or fixture
Analogue	A command voltage from the controller	Winding, tension or force control
Modbus RS-485	A daisy-chained serial bus	Monitoring and parameters from an HMI
EtherCAT, Profinet or CANopen	A single network link	Synchronised multi-axis motion

A Typical Servo Drive Application in Bengaluru

Picture a typical robotic assembly cell built by an integrator near Peenya: a four-axis gantry places parts into a fixture while a rotary indexer presents the next nest. Wired the traditional way, every axis carries pulse, direction, enable, alarm and home wiring, plus a separate safety relay chain to cut motor power. Using R6 drives on EtherCAT under an RM500 motion controller reduces that to one network cable per drive, lets the controller coordinate interpolated moves, and uses the drives' STO input for the safety function. Fault codes appear on the HMI, so a technician knows which axis stopped and why.

Where Servo Drive Projects Slip

Factory gain settings left in place on a heavy or springy mechanism.
Encoder leads without screening, or a poor earth bond, triggering random faults.
Hard-stopping or vertical axes with nowhere to dump regenerated energy.
STO wired in without a clear view of the safety function it should deliver.
Overtravel and reference switches never connected.

Every family we supply to the city is on the Bengaluru industrial automation page.

Conclusion

In a Bengaluru robotic cell, precision stage or retrofit, a drive earns its place by fitting three things: the motor it powers, the mains it runs on and the language your controller speaks. Share those with RB Automation and we will name the Rtelligent drive that fits.

Frequently Asked Questions

Which servo drives do you supply in Bengaluru?

We supply Rtelligent R5 and R6 series AC servo drives, and the S5L and S6L series with RS-485 Modbus, dispatched to Bengaluru from Ahmedabad.

Which servo drive suits an EtherCAT robotic cell?

The R6 series offers EtherCAT, Profinet, CANopen or Modbus options along with STO, which makes it the usual choice for multi-axis robotic cells with an EtherCAT motion controller such as the RM500.

What is STO on a servo drive?

STO (safe torque off) removes torque from the motor through a dedicated safety input, so the safety circuit can stop the axis without relying only on the controller. The R6 series includes it.

Can I connect a servo drive to 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 network drive. Share the PLC model so we can confirm.

What is the price of a servo drive in Bengaluru?

There is no fixed price list. The price depends on the drive series, power, interface, matching motor and quantity. Use the form on this page, call +91 8511104864 or email contact@rbautomate.com for a quotation.
