Servo Drive Supplier in Rajkot: Buying Guide

Key Takeaways

Rajkot CNC and SPM builders run R5 and R6 servo drives from PLC pulses or EtherCAT.
The R6 adds STO and fieldbus options such as EtherCAT, Profinet, CANopen and Modbus.
The S5L and S6L offer RS-485 Modbus with position, speed and torque control.
Earthing, shielded encoder cables and gain tuning decide how well the axis performs.

On a Rajkot CNC retrofit or special purpose machine, the servo drive is where most of the commissioning time goes. It closes the current, speed and position loops, protects the motor, and links the axis to the PLC or CNC controller. Builders and plant engineers who need a servo drive supplier in Rajkot can order Rtelligent AC servo drives and their matching motors from RB Automation. We dispatch from Ahmedabad and answer selection and set-up questions by phone, WhatsApp and email.

Servo Drives on Rajkot Machines

CNC and SPM builders in Aji GIDC, Bhaktinagar and on Gondal Road run R5 and R6 drives from PLC pulses or EtherCAT on retrofits, bar feeders and machining SPMs. Engine and auto component lines at Metoda GIDC, Shapar-Veraval and Kuvadva use servo axes on transfer and assembly machines. Packaging machine builders in the city use servo drives on film feed and sealing. In foundry-adjacent shops with heavy electrical noise, good earthing and properly shielded encoder cables are what keep these drives free of nuisance alarms.

Inside a Servo Drive

The drive receives a command, whether a train of pulses, an analogue voltage or a message on a network, and turns it into motor current. It reads the motor encoder all the time and adjusts that current so the axis follows the command even as the load changes. Gain settings decide how stiff and quick the axis feels; good tuning removes overshoot and vibration without making the axis sluggish.

R5 series: AC servo drives for general machine axes.
R6 series: built on an ARM and FPGA platform with STO, analogue control and EtherCAT, Profinet, CANopen or Modbus options.
S5L series: AC servo drives with RS-485 Modbus and position, speed and torque control.
S6L series: also offering RS-485 Modbus networking with position, speed and torque modes.

The AC servo drive page has more detail, and the motors that pair with these drives are covered in the Rajkot servo motor guide.

Selecting a Servo Drive

Fix the motor first, because each drive is sized to a particular motor power and encoder type.
Confirm the supply in the panel.
Choose the command method your PLC, CNC or motion controller can provide.
List the I/O: limit and home sensors, brake output, alarm and ready signals.
Check whether fast stops or a vertical axis call for a braking resistor.
For safety functions, check whether the drive offers STO, as the R6 does.

Three Ways to Command a Servo

Pulse and direction. The simplest link, used when a PLC with high-speed outputs such as the RX3U or RX8U runs a few axes.

Analogue reference. A speed or torque command as a voltage, still common on retrofits where an older CNC controller provides the signal, and in tension and winding control.

Fieldbus. Commands, feedback and alarms on one cable. The RM500 EtherCAT controller and the R6 drive suit multi-axis machines where wiring and diagnostics matter.

Signs a Servo Drive Needs Replacing

Usual triggers are over-current or encoder faults that keep coming back, a drive that runs hot, or an obsolete model whose spares have dried up. The warning signs are listed in more detail in signs it's time to replace your AC servo drive.

Rtelligent Servo Drive Series for Rajkot Builds

Series	Notable features	Good fit
R5	General purpose AC servo drive	Pulse-commanded retrofit and SPM axes
R6	ARM+FPGA, STO, analogue, EtherCAT / Profinet / CANopen / Modbus options	Networked multi-axis machines and safety needs
S5L	RS-485 Modbus; position, speed and torque control	Machines controlled over Modbus from a PLC or HMI
S6L	RS-485 Modbus; position, speed and torque control	Machines controlled over Modbus from a PLC or HMI

Power ranges and interface details differ by model and are listed on each product page; we confirm the motor and drive pairing before you order.

Command Method by Controller

Your controller	Likely command method	Notes
Pulse-type PLC (RX3U, RX8U, MX3G combo)	Pulse and direction	Simple wiring for one to a few axes
Older CNC controller on a retrofit	Analogue speed reference or pulse	Check the controller's output type first
Modbus PLC or HMI	RS-485 Modbus	Speeds, positions and faults over one cable
EtherCAT motion controller (RM500)	EtherCAT	Synchronised multi-axis motion and diagnostics

A Typical Servo Drive Application in Rajkot

Think of a typical multi-spindle drilling and tapping SPM built in Aji GIDC for an engine component plant. A servo slide feeds the drilling head, a second servo feeds the tapping head, and an indexing table moves the part between them. With pulse drives each axis needs its own pulse, direction, alarm and ready wiring back to the PLC. Using R6 drives on EtherCAT with an RM500 controller puts all three on one network cable, lets the HMI show which axis faulted, and allows the tapping feed to be locked to the spindle speed in software. Where the buyer's safety rules call for it, the R6's STO input can be wired into the guard circuit.

Common Servo Drive Mistakes to Avoid

Leaving gains at factory values on a heavy slide and living with vibration.
Sharing an earth point with welding or furnace equipment.
Omitting the braking resistor on axes that decelerate hard.
Wiring limit and home switches only to the PLC when the drive also expects them.

Frequently Asked Questions

Which servo drives do you supply to Rajkot?

We supply Rtelligent R5 and R6 series AC servo drives and the S5L and S6L series, with matching servo motors, from our base in Ahmedabad.

Can a servo drive take commands from an older CNC controller?

Often yes. Many older controllers give an analogue speed reference or pulse output, and the drive can be set to follow it. Share the controller model and its output type so we can check.

Which of your servo drives support EtherCAT?

The R6 series offers EtherCAT as well as Profinet, CANopen and Modbus options. The S5L and S6L series offer RS-485 Modbus networking.

Why does my servo drive show encoder or noise alarms?

Common causes are poor earthing, unshielded or damaged encoder cables and encoder cables run next to power cables. Check these before replacing the drive.

What is the price of a servo drive in Rajkot?

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