UNITTA Equipment We Repair — By Category
UNITTA Product Lines We Repair
Our engineers are trained on the full UNITTA product range. Below are the major product families we service.
UNITTA Safety-Rated PLCs (UTS/UTR Series)
Safety-certified programmable logic controllers designed for hazardous areas in textile mills and chemical plants. Common faults include watchdog timer resets, input module degradation, and safety relay coil failures from humidity and vibration exposure.
UNITTA Motion Control Modules (UCM Series)
Dedicated motion controllers for spinning frames, winder drives, and packaging machinery. Repair focus includes encoder signal loss, PWM output stage failures, and CAN fieldbus communication errors in humid mill environments.
UNITTA Servo Drive Systems (USD Series)
Compact servo drives for precision positioning in pharmaceutical filling, textile take-up, and label application machinery. Common issues: gate driver failures, current sense circuit drift, and thermistor sensor open-circuit conditions.
UNITTA HMI Touch Panels (UTH Series)
Industrial 7-inch to 15-inch touchscreen interfaces for textile and sugar plant operator stations. Repair includes backlight failure, capacitive touch sensor malfunction, and RS485 communication card faults.
UNITTA Analog I/O Modules (UAI Series)
High-precision 16/32-channel analog input/output cards for process monitoring in pharmaceutical and chemical manufacturing. Issues: ADC reference drift, output DAC linearity loss, and thermocouple cold-junction compensation failures.

Common UNITTA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in UNITTA equipment arriving at our workshop.
- ✓UNITTA UTS/UTR safety PLC watchdog timeout resets — Moisture ingress into CPU module causes intermittent signal integrity issues on internal data bus; common in coastal textile mills and sugar plants with high humidity. Aged electrolytic capacitors near power supply also contribute.
- ✓UNITTA UCM motion controller encoder signal loss and jitter — Vibration from spinning frames and winding machinery loosens encoder connector pins and degrades shielded twisted pair cabling. Salt spray in coastal mills accelerates corrosion of encoder connectors.
- ✓UNITTA USD servo drive gate driver failure and phase leg shutdown — Thermal cycling in uncontrolled plant environments and inadequate heatsink contact causes gate driver IC degradation. Transient over-voltage from motor winding kick-back stresses gate drive circuits rated for 48V/96V operation.
- ✓UNITTA UTH HMI touchscreen backlight failure and dim display — High ambient temperature in mill floors and chemical plants degrades backlight inverter circuits. CCFL/LED backlight aging combined with electrolytic capacitor drying reduces brightness over 3-5 years.
- ✓UNITTA UAI analog module ADC linearity drift and measurement error — Process heat, dust, and thermal cycling cause reference voltage IC drift and precision resistor tolerance stack-up. Cold-junction compensation fails in RTD/thermocouple modules due to sensor isolation issues.
- ✓UNITTA CAN fieldbus communication errors and node dropout — Noisy electrical environment in sugar plants with VFDs and soft starters couples EMI into CAN bus twisted pairs. Loose connectors and water ingress into junction boxes cause intermittent frame loss and protocol timeouts.

All repairs are completed at our Vadodara, Gujarat facility with 24/7 testing and same-day technical reporting.
Can Synchronics repair UNITTA safety-rated PLCs with certification requirements?+
Yes. Our engineers are trained in UNITTA safety programming standards and functional safety principles. We repair UTS and UTR safety-rated PLCs with full diagnostic testing of safety relay outputs, watchdog circuits, and E-stop chain validation. Repairs include firmware verification against original code backups and safety proof-testing before return. We maintain detailed test records for compliance audits in pharmaceutical and hazardous area applications.
What is the typical repair turnaround time for UNITTA motion controllers?+
UNITTA UCM and servo drive repairs typically take 7-10 working days from receipt. Diagnosis and parts availability is 2-3 days; component replacement, calibration, and burn-in testing takes 3-5 days. Emergency express repairs can be arranged for critical production holds - contact our support team with equipment serial numbers for priority scheduling. We maintain stock of UNITTA encoder modules and servo components for faster turnaround.
Do you provide spare parts for UNITTA equipment or recommend aftermarket alternatives?+
Synchronics sources genuine UNITTA replacement components through authorized distributors and direct Bangalore factory contacts. For obsolete UNITTA modules, we recommend tested equivalent industrial components (e.g., Siemens, Delta, or Mitsubishi) with firmware mapping and terminal block re-wiring to match your existing system. All alternatives are validated on our test bench before installation. We also offer refurbished UNITTA modules at competitive rates with 12-month warranty.
How do I ship UNITTA equipment to Synchronics for repair?+
Contact our intake team at support@synchronics.co.in or call our Vadodara facility to arrange pickup. We provide insulated cardboard boxes with foam padding for all PLC and servo equipment. Large motion controller assemblies can be collected by our logistics partner within 24 hours in most Indian cities. Once received, you will get a digital inventory receipt, fault diagnosis report within 48 hours, and a fixed repair quote before work begins. Return shipping is insured and tracked.
How do I send my UNITTA 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 UNITTA 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 UNITTA 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 UNITTA 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.
