ADB-SIEMENS Product Lines We Repair
Our engineers are trained on the full ADB-SIEMENS product range. Below are the major product families we service.
SINAMICS G120 Drive Series
Compact general-purpose AC drives for pumps, fans, compressors, and conveyors. Common faults include IGBT short-circuits, capacitor degradation, and EMC filter failures causing nuisance trips and loss of motor control.
SINAMICS G110 Compact Drives
Space-saving single-phase to three-phase and three-phase AC drives for light-duty industrial applications. Frequently repaired for thermal shutdown issues, control signal loss, and auxiliary transformer failures.
SINAMICS S120 Servo Drive System
High-precision servo drives for CNC machines, injection molding presses, and positioning systems. Repair focus includes encoder interface faults, resolver signal conditioning errors, and closed-loop servo loop instability.
ADB Analog Drives and Legacy Systems
Older ADB stand-alone analog and digital drive controllers used in Indian textile mills and food processing plants. Repairs address potentiometer drift, relay coil burnout, and obsolete component sourcing challenges.
SINAMICS Power Modules and Rectifier Units
Multi-axis power supply and rectifier modules for industrial drive systems. Common failure modes: bus capacitor ripple-induced busbar arcing, diode bridge open circuits, and thermal management defects.
Gate Drive and Control Electronics
Isolated gate driver cards, pulse transformers, and microcontroller boards within ADB-SIEMENS drive cabinets. Failures stem from desaturation failures, shoot-through events, and firmware corruption under industrial EMI.

Common ADB-SIEMENS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ADB-SIEMENS equipment arriving at our workshop.
- ✓IGBT short-circuit and thermal runaway shutdown — IGBT junction failure due to transient voltage spikes from motor cable capacitance, inadequate snubber networks, or manufacturing defects in aged power modules. Temperature rise triggers protection and halts all drive output.
- ✓DC bus capacitor ripple voltage and voltage dips — Electrolytic capacitor dry-out or bulging caused by prolonged exposure to >60°C ambient temperatures, mains voltage instability, and inadequate cooling in tropical Indian climates. Drive protection circuits detect low bus voltage and inhibit output.
- ✓Fault code F06.20 or F07.10 encoder/resolver communication loss — Corroded M23 encoder connectors, broken signal shielding, or resolver winding insulation breakdown common in humid textile and dye house environments. Loss of feedback signal forces drive into safe-state shutdown.
- ✓Gate driver desaturation fault and no switching output — Gate driver IC failure due to voltage spikes from long motor cables, loss of isolated 15V supply, or optocoupler degradation. IGBT bases receive insufficient drive current, preventing conduction and halting motor drive.
- ✓Overtemperature protection trips during normal motor load — Internal heat sink thermal interface material (TIM) degradation, faulty NTC thermistor sensors giving false high-temperature readings, or insufficient cooling air circulation due to cabinet design. Drive derate or shuts down to prevent IGBT destruction.
- ✓Control module non-responsiveness and communication timeout errors — Microcontroller EEPROM bit-flip corruption, CAN or RS485 transceiver IC failure, or loss of 24V auxiliary control power from corroded terminal blocks. Drive becomes unresponsive to external command signals.

What does Synchronics charge for ADB-SIEMENS G120 or S120 drive repair?+
Repair cost depends on fault type and component replacement scope. IGBT replacement or capacitor refresh: INR 8,000-15,000. Gate driver or control module rebuild: INR 12,000-18,000. Complex servo tune and resolver validation: INR 15,000-25,000. We provide upfront quotation after failure diagnosis and log all work in our technical database for future reference.
How long does ADB-SIEMENS drive repair typically take at Synchronics?+

Servo system firmware restoration and calibration: 7-10 business days. We offer emergency express service for critical production-critical drives — contact our dispatch team for same-day assessment.
Can Synchronics repair ADB-SIEMENS drives with corrupted or missing firmware?+
Yes. Synchronics has access to licensed firmware repositories for ADB-SIEMENS SINAMICS G120, G110, and S120 series. We restore factory or customer-specific configurations via JTAG, RS485, or USB programming interfaces. We validate all parameter sets and motor tuning curves before returning equipment to ensure proper speed ramp, acceleration, and thermal derating behavior.
Do you offer ADB-SIEMENS drive testing and certification after repair?+
Yes. All repaired ADB-SIEMENS drives undergo full functional validation including no-load spin test, load profile simulation, thermal imaging under rated current, and communication protocol loopback verification. We issue a signed test report with oscilloscope waveforms, ripple voltage measurements, and gate drive timing data. 12-month warranty covers parts and labor.
How do I send my ADB-SIEMENS 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 ADB-SIEMENS 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 ADB-SIEMENS 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 ADB-SIEMENS 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.
