Servo Drive Supplier in Ludhiana: Buying Guide

Key Takeaways

R5 and R6 servo drives suit Ludhiana's press feeders and the knitting machines rebuilt around Focal Point.
RB Automation supplies Rtelligent R5, R6, S5L and S6L servo drives to Ludhiana from Ahmedabad.
Choose the drive by its matched motor, the supply and how the controller commands it: pulse, analogue or fieldbus.
Earthing, shielded encoder cables and gain tuning decide how well a servo axis performs.

Walk through the press shops of Dhandari Kalan or the knitting workshops around Focal Point and you will see more and more machines where a belt, a cam or a mechanical gear train has been swapped for an electronic axis. Behind each of those axes sits a servo drive: the unit that powers the motor, watches its encoder and obeys the PLC. Choosing it well decides whether the rebuilt machine feels crisp or keeps tripping. RB Automation is a servo drive supplier for Ludhiana, sending Rtelligent AC servo drives and their paired motors from Ahmedabad, with sizing help over phone, WhatsApp and email.

Where Ludhiana Puts Servo Drives to Work

Press feeders in the forging and fastener belt

Sheet metal, forging and fastener units at Dhandari Kalan, Gill Road, Sahnewal and Kanganwal use R5 and R6 drives on roll feeders. The operator keys in a new strip length on the HMI rather than changing gears.

Knitting machine rebuilds around Focal Point

Rebuilders give yarn feed, fabric take-down and winding their own axes, so each can be set separately for a new fabric or yarn count.

Machine tool retrofits

Lathes and milling machines from Ludhiana's machine tool trade gain electronic feed axes run by a fresh controller.

Bicycle, auto and tractor part machinery

Transfer, assembly and gauging machines built in Industrial Areas A and B use servo axes where cycle time is tight.

What the Drive Actually Does

Every servo drive runs three nested loops. The innermost loop regulates motor current, the next holds speed, and the outer one keeps position. The command arriving from outside can be a pulse train, a voltage reference or a network telegram; the drive compares it against encoder feedback thousands of times a second and corrects the current. Gain values set how firmly the motor resists disturbance, which is why each installation needs a short tuning session with the real load.

The Rtelligent Drive Line-Up

R5: AC servo drive for everyday machine axes like feeders and transfer slides.
R6: AC servo drive for everyday work and for tougher axes.
S5L: 50 W to 2 kW, with RS-485 Modbus networking.
S6L: 100 W to 2 kW, also with RS-485 Modbus.

Across these series you can command the axis by pulses, by an analogue signal or over a fieldbus. Specifications sit on the AC servo drive page, and motor pairing is covered in the servo motor guide for Ludhiana.

Matching the Command Method to the Machine

Pulse train: a one- or two-axis press feeder fed by a PLC with fast outputs, such as the Rtelligent RX3U, is the classic case.
Analogue signal: yarn take-up and fabric winding, where holding tension or torque matters more than an exact position.
Network: a transfer or assembly machine with many axes, coordinated by a controller like the RM500 over EtherCAT, with one cable linking the axes.

A Five-Point Selection Checklist

Pick the motor first; the drive size and encoder interface follow from it.
Note what the cabinet offers: single-phase or three-phase mains, as rated for the drive and motor.
Confirm which command method your PLC or controller can produce.
Write down the signals you need: overtravel limits, home switch, brake release, fault and ready.
Think about energy coming back from the load: hard stops, big feed rolls and lifting axes may call for a braking resistor.

Installation Habits That Pay Off

Ludhiana press shops are electrically noisy places, with welding sets, induction heaters and large motors nearby. Bond the drive and motor to a solid earth, keep encoder cables shielded and in a separate tray from power wiring, and tune the gains with the real feed rolls fitted. When an older drive keeps throwing over-current or encoder faults, runs hot, or has no spares left, it may be time to change it; our article signs it's time to replace your AC servo drive lists the warning signs.

R5, R6, S5L and S6L Side by Side

Drive	Supply	Typical Ludhiana axis
R5	AC mains	Roll feeders and transfer slides
R6	AC mains	Feeders and more demanding retrofit axes
S5L	AC mains, RS-485 Modbus	Networked feeders and slides
S6L	AC mains, RS-485 Modbus	Networked feeders and slides

Each product page lists the power ratings and interfaces of its models, and we check that the drive and motor are a true pair before anything is dispatched.

Which Command Method Suits Which Ludhiana Machine

Machine	Command	Reason
Single-axis press feeder	Pulse train from the PLC	Simple wiring, feed length set as a pulse count
Rebuilt knitting machine take-down or winder	Analogue reference	Tension and torque matter more than exact position
Multi-axis assembly or transfer machine	EtherCAT or other fieldbus	One cable, shared diagnostics, coordinated moves

A Typical Servo Drive Application in Ludhiana

Consider a typical knitting machine rebuild. Originally one motor turned the yarn feed, the take-down rollers and the fabric winder through belts and gears, so changing fabric meant changing pulleys. After the rebuild, each function gets its own servo axis. The take-down and winder hold tension through an analogue or fieldbus reference, and that tension stays even as the fabric roll grows heavier. If an axis faults, the HMI names it, so the fitter goes straight to the right drive instead of tracing wires through the panel.

Where Servo Drive Projects Go Wrong

Leaving the gains at factory values with a heavy feed roll fitted, so the axis overshoots or hums.
Encoder cables laid next to welding or induction heater cables, causing noise alarms.
No regeneration resistor on an axis that brakes hard or carries a big roll.
Overtravel and home switches never wired, so a crash is only stopped by the hard stop.

Information We Need to Quote a Servo Drive

Motor part number, or its power and encoder type
Mains or DC supply available in the cabinet
How the controller will command it, and the PLC or controller model
Signals needed: limits, home, brake, fault
Number of drives
