BONAS Product Lines We Repair
Our engineers are trained on the full BONAS product range. Below are the major product families we service.
BONAS Jacquard Control Systems
Electronic jacquard head controllers and control cards for complex pattern weaving. Common issues include burnt control boards, harness wire breakage, solenoid failures, and pattern memory corruption requiring firmware reloading.
BONAS Dobby Mechanisms & Electronics
Automated dobby head systems with electronic actuation and timing control. Repairs involve solenoid replacement, spring tension adjustment, proximity sensor calibration, and electrical connector corrosion cleaning.
BONAS Loom Interface & Drive Electronics
Main control electronics interfacing looms with dobby and jacquard units. Typical faults: power supply failures, relay burnout, sensor interface errors, and communication protocol failures between loom and BONAS controllers.
BONAS Weaving Pattern Software & Modules
Pattern generation, storage, and recall modules for dobby and jacquard looms. Issues include corrupted pattern files, EPROM failures, USB/serial communication breakdowns, and outdated firmware needing updates.
BONAS Mechanical & Electrical Spares
Replacement harnesses, connectors, springs, solenoids, and mechanical components for BONAS assemblies. We stock and repair OEM-equivalent parts for rapid mill restarts and preventive maintenance programmes.

Common BONAS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BONAS equipment arriving at our workshop.
- ✓Jacquard Control Card Power Failure — BONAS jacquard control cards typically fail due to overheating from poor ventilation in mill environments, or catastrophic electrolytic capacitor failure after 8-12 years of operation in high-humidity textile factories.
- ✓Dobby Solenoid Coil Open Circuit — BONAS dobby solenoids fail when repeated loom vibration and thermal cycling cause winding insulation breakdown, or when moisture ingress corrodes internal copper windings in poorly ventilated mill spaces.
- ✓Harness Connector Intermittent Contact — BONAS harness connectors develop intermittent contact when subjected to daily loom vibration, dust accumulation in cotton/synthetic mills, or corrosion from high humidity and ammonia-based dyes. Pin oxidation and spring loss are common in 3+ year old installations.
- ✓Pattern Memory Corruption or Loss — BONAS EPROM modules and pattern memory cards fail due to repeated power cycles in mills with unstable mains supply, battery-backed SRAM failure, or file system errors during firmware updates.
- ✓Power Supply Output Voltage Sag or Dropout — BONAS 48V power supplies fail when thermal overload causes regulator shutdown, or when filter capacitors age and lose capacitance in 60+ degree mill environments. Input rectifier diodes may also short under surge conditions.
- ✓Sensor Interface Communication Loss — BONAS sensor interface boards lose communication with loom proximity/photoelectric sensors when cable shielding is damaged, connectors corrode in humid mill environments, or optical sensors accumulate dust and require cleaning.

Frequently Asked Questions — BONAS Repairs
Do you repair BONAS equipment anywhere in India?+
Yes. Synchronics repairs the complete BONAS textile machinery electronics range — jacquard controllers, dobby systems, loom interfaces, power supplies, and pattern memory modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Ahmedabad, Chennai, Hyderabad, Bengaluru, and all other cities. All repairs are performed at our facility in Vadodara, Gujarat, with 3-7 day turnaround for most faults.
I have a BONAS jacquard loom with a burnt control card and no spare parts. Can Synchronics help?+
Absolutely. Synchronics specialises in repairing damaged BONAS jacquard control cards through component replacement, PCB restoration, and firmware reload. We source OEM-equivalent replacement components and test pattern memory integrity before return. If parts are unavailable, we rebuild functional cards from salvaged modules. We also stock reconditioned cards for emergency situations.
What is the typical turnaround time for BONAS dobby solenoid repair?+
Standard turnaround is 3-4 days for BONAS dobby solenoid replacement and mechanical testing. Express service (48 hours) is available for critical production scenarios. We keep OEM-equivalent solenoid assemblies in stock and test actuation response and timing before return. Your loom will be production-ready without waiting for overseas replacement parts.
Can Synchronics recover lost weaving patterns from a BONAS jacquard card that crashed?+
Yes. If your BONAS pattern memory module is corrupted but the card is not physically destroyed, Synchronics can often recover data or reflash with backup files if available. We maintain extensive pattern libraries and can assist with firmware restoration. If original patterns are lost, we advise keeping backups on USB or cloud storage and installing UPS systems to prevent future power-related failures.
Do you offer preventive maintenance programmes for BONAS equipment in Indian mills?+
Yes. Synchronics offers preventive maintenance contracts for BONAS textile machinery, including quarterly inspections, capacitor and connector replacement, solenoid testing, and firmware validation. We can schedule visits to your mill in Gujarat, Maharashtra, Tamil Nadu, or elsewhere in India. Preventive maintenance reduces unplanned downtime and extends equipment life by 3-5 years.
How do I send my BONAS 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 BONAS 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 BONAS 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 BONAS 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.
