ALLFAVOR Product Lines We Repair
Our engineers are trained on the full ALLFAVOR product range. Below are the major product families we service.
ALLFAVOR VFD Series (AF-Drive)
Variable frequency drives ranging 0.75 kW to 250 kW for motor speed control in pumps, compressors, and conveyor systems. Common failures include IGBT module degradation, DC bus capacitor aging, and firmware corruption under voltage spikes.
ALLFAVOR Servo Motion Controller (AF-SM)
Closed-loop servo controllers for precision positioning in CNC machines, packaging equipment, and textile machinery. Repair demand centers on encoder interface faults, current loop instability, and PID tuning parameter loss.
ALLFAVOR Modular PLC (AF-Logic)
Compact programmable logic controllers with analog I/O, Ethernet, and Modbus/CANopen connectivity for small to mid-scale automation. Typical issues include relay module burnout, communication port failures, and program memory corruption.
ALLFAVOR Distributed I/O Terminals (AF-IO)
Remote input-output modules designed for harsh factory environments with IP67 ratings and wide temperature tolerance. Field failures often stem from connector corrosion, isolation barrier breakdown, and module communication timeouts.
ALLFAVOR HMI Touch Panels (AF-View)
7-inch to 15-inch industrial touchscreen interfaces for process monitoring and operator control. Common repairs involve LCD backlight failure, touch sensor calibration loss, and serial communication degradation.
ALLFAVOR Power Supply Modules (AF-PSU)
24 VDC and 48 VDC regulated supplies with 20A to 60A output for industrial control cabinets. Frequent failure modes include transformer primary winding insulation breakdown, output rectifier diode short circuits, and thermal runaway under overload.

Common ALLFAVOR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ALLFAVOR equipment arriving at our workshop.
- ✓ALLFAVOR VFD F02 Overvoltage Fault on Startup — Regenerative energy from motor deceleration exceeds DC bus brake resistor capacity, or brake chopper circuit transistor fails. Common in high-inertia load applications (fans, pumps, conveyors) without external braking modules.
- ✓ALLFAVOR Servo AF-SM Encoder Communication Loss — Encoder cable shielding degradation, loose M12 connector pins, or optical receiver IC failure within the servo controller. Typical in high-vibration environments (textile looms, injection molding machines) where connectors experience mechanical stress.
- ✓ALLFAVOR PLC AF-Logic Program Memory Corruption — Unexpected power loss without proper shutdown sequence, or firmware update interrupted mid-flash. Memory bit flip can also occur due to inadequate power supply filtering or ESD events during routine maintenance.
- ✓ALLFAVOR I/O Module AF-IO Terminal Timeout Error — CANopen or Modbus RTU gateway communication drops due to cable impedance mismatch, termination resistor missing at line ends, or galvanic isolation barrier failure in the I/O board.
- ✓ALLFAVOR HMI AF-View Touch Panel Unresponsive Display — LCD backlight LEDs age or fail after 30,000+ operating hours; touch sensor capacitive coupling drifts due to humidity or electromagnetic interference from nearby VFDs; serial communication link to PLC is corrupted.
- ✓ALLFAVOR PSU AF-PSU-24 Output Voltage Collapse Under Load — Primary transformer turns ratio drift after thermal cycling, main output rectifier bridge diodes forward bias loss, or output filter capacitor equivalent series resistance (ESR) increase due to age and operational stress.

Frequently Asked Questions — ALLFAVOR Repairs
Do you repair ALLFAVOR equipment anywhere in India?+
Yes. Synchronics provides comprehensive ALLFAVOR repair across the full product portfolio — VFDs, servo controllers, PLCs, I/O terminals, HMI panels, and power supplies. We offer door pickup and delivery in Mumbai, Delhi, Pune, Hyderabad, Chennai, Bangalore, Ahmedabad, Surat, Vadodara, and all major Indian industrial cities. Our Vadodara facility houses ALLFAVOR test benches, firmware programming stations, and spare component inventory for rapid turnaround.
What warranty do you provide on ALLFAVOR drive and servo repairs?+
All ALLFAVOR equipment repaired at Synchronics comes with 12-month manufacturer-equivalent warranty covering parts and labor. We use genuine ALLFAVOR-compatible components for critical replacements (IGBTs, capacitors, control boards) and perform 72-hour burn-in testing before dispatch. Extended 24-month warranty is available for high-reliability applications in food and pharmaceutical industries.
Can Synchronics repair ALLFAVOR VFDs with custom firmware or parameter backups?+
Absolutely. Our engineers have access to ALLFAVOR firmware development kits and programming tools. If you provide original parameter backups (.cfg or .bak files), we restore your custom drive tuning, acceleration profiles, and communication protocols exactly as configured. If backups are unavailable, we reverse-engineer settings from your motor nameplate and application specifications.
How long does ALLFAVOR VFD or servo repair typically take at Synchronics?+
Standard ALLFAVOR drive repairs (capacitor replacement, IGBT module swap, firmware reload) take 5-7 working days. Complex servo encoder repairs and PLC memory recovery may require 10-14 days for component sourcing and multi-step validation. We offer express 48-hour turnaround on standby units for production-critical machines, subject to parts availability.
Why is my ALLFAVOR AF-D VFD throwing F01 and F03 error codes alternately?+
F01 (overvoltage) and F03 (phase loss) alternating faults typically indicate a failing power supply module inside the drive cabinet, causing voltage rail instability. ALLFAVOR drives detect this as intermittent mains detection loss. Synchronics diagnosis involves: (1) AC mains voltage and phase sequence check with three-phase analyzer, (2) VFD input contactor coil voltage confirmation, and (3) internal PSU output ripple and regulation measurement. We replace failed PSU boards and verify all three-phase mains connectivity before returning the drive.
How do I send my ALLFAVOR 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 ALLFAVOR 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 ALLFAVOR 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 ALLFAVOR 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.
