BNB CONTROLS Product Lines We Repair
Our engineers are trained on the full BNB CONTROLS product range. Below are the major product families we service.
BNB SmartDrive VFD Series
Variable frequency drives for three-phase induction motors. Common issues include IGBT module failures, capacitor degradation, firmware corruption, and input/output card malfunctions affecting speed control and motor protection.
BNB CompactPLC Control Systems
Modular programmable logic controllers for discrete and process automation. Typical repairs involve corrupted ladder logic programs, analog input module failures, relay output card damage, and communication interface faults.
BNB SmartHMI Touch Panels
Industrial human-machine interfaces with resistive and capacitive touch screens. Common problems include display backlight failure, touchscreen digitizer degradation, power supply faults, and serial communication port damage.
BNB ServoPro Motion Controllers
Servo drive controllers for precision positioning and synchronization. Typical faults include encoder signal loss, PWM output failures, feedback loop instability, and thermal runaway conditions in stepper and servo motors.
BNB FieldLink IO Modules
Distributed input-output modules for field sensing and actuation over Modbus and Profibus networks. Common issues involve relay contact wear, optoisolator degradation, surge protection failures, and protocol communication errors.

Common BNB CONTROLS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BNB CONTROLS equipment arriving at our workshop.
- ✓BNB SmartDrive IGBT module short circuit — Thermal cycling and vibration in heavy industrial environments cause IGBT solder joint failures and gate driver circuit faults in power stages. Inadequate heatsink contact or contamination accelerates this failure mode.
- ✓BNB CompactPLC program memory corruption — Power supply transients, electromagnetic interference, or failed backup battery cause firmware corruption and loss of ladder logic programs. Indian industrial environments with unstable grid conditions make this common.
- ✓BNB SmartHMI backlight and LCD failure — LED backlight aging, capacitor degradation in high-ambient-temperature plants, and power surge damage to LCD driver circuits cause display dimming or complete blackout.
- ✓BNB ServoPro encoder signal loss during runtime — Loose or corroded encoder connectors, damaged encoder cable shielding, or internal encoder bearing wear result in intermittent or complete loss of position feedback and servo loop faults.
- ✓BNB FieldLink module relay contact chattering — Mechanical bounce from inductive transient switching, carbon buildup on relay contacts from arcing, and inadequate snubber protection cause erratic output switching and false sensor signals.
- ✓BNB SmartDrive Modbus communication timeout errors — RS-485 network noise in metal fabrication shops, loose termination resistors, or corrupt communication firmware cause CRC errors and loss of network connectivity with master controllers.

Frequently Asked Questions — BNB CONTROLS Repairs
Do you repair BNB CONTROLS equipment anywhere in India?+
Yes. Synchronics repairs the full BNB CONTROLS product range across all states. We offer same-day collection from major metros including Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all smaller industrial cities. Equipment is transported to our Vadodara facility for repair and tested before return shipment. Most repairs complete within 5-7 working days.
Can you reprogram BNB CONTROLS PLCs if our original program is lost?+
Partial recovery is possible. If your PLC backup file exists, we directly reprogram. If lost, we can extract ladder logic from your wiring schematics and I/O mapping documents. We also support exporting memory dumps for reverse-engineering. For complex programs, we recommend contacting BNB CONTROLS directly or consulting your original system integrator.
What is the turnaround time for BNB SmartDrive VFD repair?+
Standard turnaround is 5-7 working days depending on fault severity. IGBT replacements and capacitor bank rebuilds typically take 3-4 days. Firmware reflashing and functional load-testing add 1-2 days. We offer express 48-hour turnaround for critical production line equipment with rush diagnostic fee.
Do BNB CONTROLS drives work with existing non-BNB motors in our plant?+
Yes, BNB SmartDrive VFDs are compatible with standard three-phase squirrel-cage induction motors from all manufacturers. However, motor overload protection tuning and thermal constants must match your specific motor nameplate. Synchronics can assist with motor parameter setup during commissioning after repair completion.
What warranty do you provide on repaired BNB CONTROLS equipment?+
Synchronics provides 12 months parts warranty and 6 months labor warranty on all repaired BNB CONTROLS equipment. This covers failed components and workmanship defects. We also offer optional extended warranty up to 24 months at nominal cost. Warranty terms exclude physical damage, electrical surge damage, and improper installation.
How do I send my BNB CONTROLS unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a BNB CONTROLS drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on BNB CONTROLS repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your BNB CONTROLS unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
