Key Takeaways
- R6 and S6L drives suit the multi-axis gantries and handling systems built by Pune's SPM makers.
- RB Automation supplies Rtelligent R5, R6, S5L and S6L servo drives to Pune from Ahmedabad.
- Pick the drive on the matched motor, the supply and the control mode your PLC or motion controller uses.
- Fieldbus drives with an EtherCAT motion controller cut wiring and speed up fault-finding on multi-axis machines.
A multi-axis gantry built in Bhosari for a machining cell in Chakan may carry three or four servo axes, and every one of them depends on its drive. The drive closes the control loops, protects the motor and decides how the axis talks to the PLC. RB Automation works as a servo drive supplier in Pune for line builders, SPM makers and plant maintenance teams: we dispatch Rtelligent AC servo drives and their paired motors from Ahmedabad, and help you settle on the series and the command interface before you order.
Inside a Servo Drive
Whatever form the target arrives in, whether a pulse train, a voltage or a network telegram, the drive's task is to make the shaft obey it. Three nested loops run inside: current, speed and position. The encoder feeds the outer loops continuously, so the drive reacts the moment the load pushes back. Gain tuning decides how stiff and how quick the axis feels, and protection functions trip on overload, over-voltage and encoder faults before damage is done.
Rtelligent Servo Drives for Pune Machines
- R5 series, the everyday choice for standard machine axes.
- R6 series, for tougher duty such as the gantries and transfer units built for Pune assembly lines.
- S5L series and S6L series AC servo drives with RS-485 Modbus networking.
Depending on the model, the drives accept pulse, analogue or fieldbus commands. Browse them on the AC servo drive page, and find the paired motors in the Pune servo motor guide.
Picking the Control Mode
Pulse and direction
The quickest route on a one- or two-axis machine: a controller with fast transistor outputs, for example the RX3U pulse-type PLC, sets position by pulse count and travel sense by a direction line.
Analogue reference
A voltage that stands for speed or torque, still found on tension, winding and some torque-limited pressing tasks.
Fieldbus
On a gantry or a transfer line with several axes, a network cable carries commands, status and alarms. With a motion controller such as the RM500 EtherCAT controller, axes can be interpolated and every fault shows on the HMI by axis and code.
Servo Drive Selection Steps
- Fix the motor first, since the drive is sized to match its power and encoder.
- Check the panel supply against the drive and motor ratings.
- Settle the command interface your controller can actually produce.
- List the I/O: limit and home sensors, brake output, alarm, ready and in-position signals.
- Work out where energy goes when a heavy or vertical axis brakes; a resistor may be needed to absorb it.
Servo Drives in Pune Industry
Gantry and handling builders supplying plants in Chakan and Talegaon use servo drives on long travel axes and vertical lifts. Press shops in Bhosari and Pimpri-Chinchwad use them on servo roll feeders. Assembly line builders for component plants at Sanaswadi and Ranjangaon apply them to transfer, screw-driving and press-fit axes. Whatever the machine, good earthing, shielded encoder and motor cables kept apart from power wiring, and careful tuning decide whether the axis runs quietly or keeps tripping. Our automobile industry automation page shows the wider picture.
When a Drive Needs Replacing
Frequent trips, a drive that runs hot, or a model nobody can supply any more usually start the conversation. The article signs it's time to replace your AC servo drive covers what to check first.
Where Each Drive Series Fits on a Pune Shop Floor
| Drive series | Supply | Where Pune builders use it |
|---|---|---|
| R5 | Mains-fed | Standard single axes on SPMs, feeders and conveyors |
| R6 | Mains-fed | Gantry travel axes, transfer units and roll feeders |
| S5L | 50 W to 2 kW, RS-485 Modbus | Networked assembly fixtures |
| S6L | 100 W to 2 kW, RS-485 Modbus | Multi-axis gantries and handling units |
Exact ratings and interfaces differ from model to model; check the product page, and we verify the motor pairing before quoting.
Control Mode by Machine Type
| Machine | Command interface | Reason |
|---|---|---|
| Servo roll feeder on one press | Pulse train | A pulse-type PLC can drive it directly |
| Nut-running or pressing with a torque limit | Voltage reference | Torque or speed set straight from an analogue output |
| Gantry or transfer line with several axes | EtherCAT network | Coordinated moves, short wiring, faults named on the HMI |
A Typical Servo Drive Application in Pune
Take a typical servo roll feeder in a Pimpri-Chinchwad stamping shop, feeding steel strip into a mechanical press for brackets used by a vehicle plant. On every press stroke the feeder must push an exact length of strip and stop before the die closes. A pulse-type PLC reads the press crank angle, sends the feed command to an R6 servo drive, and waits for the in-position signal before allowing the next stroke. If the strip slips or jams, the drive's position error alarm stops the press instead of letting it punch a short pitch. Correct gain tuning for the roll inertia and a braking resistor to absorb the energy of each sharp stop keep the feeder accurate stroke after stroke.
Where Servo Drive Projects Go Wrong
- Leaving the gains at their out-of-box values when the axis carries a heavy table or long roll.
- Sharing an earth point with welding sets and press motors, then chasing random encoder trips.
- Letting regenerated energy from hard stops trip the drive on over-voltage instead of fitting a resistor.
- Keeping overtravel, homing and in-position signals out of the interlock logic.
Checklist for a Servo Drive Enquiry
- The motor it will run, or that motor's rating and encoder type
- What the panel supplies
- Which PLC or motion controller sends the commands, and how
- Signals needed: overtravel, homing, brake, fault, in-position
- How many axes, on how many machines

Frequently Asked Questions
Which servo drives do you supply in Pune?
We supply Rtelligent R5 and R6 series AC servo drives and the S5L and S6L series with RS-485 Modbus networking, with matched Rtelligent servo motors.
Which servo drive suits a multi-axis gantry?
R6 and S6L drives are a common fit for multi-axis gantries. On machines with several axes, fieldbus drives with an EtherCAT motion controller such as the RM500 simplify wiring and diagnostics.
Can a servo drive work with my existing PLC?
Usually yes. A PLC with high-speed pulse outputs can run a servo in pulse mode, and a fieldbus PLC or motion controller can use a fieldbus drive. Share your PLC model to confirm.
Do you provide on-site commissioning in Pune?
No. RB Automation has no service team in Pune. We supply the drive from Ahmedabad and help with parameter and wiring questions by phone, WhatsApp and email.
What is the price of a servo drive in Pune?
There is no fixed price list. The price depends on the drive series, power, control mode, matching motor and quantity. Use the form on this page, call +91 8511104864 or email contact@rbautomate.com for a quotation.
