GRAVI DRIVE Product Lines We Repair
Our engineers are trained on the full GRAVI DRIVE product range. Below are the major product families we service.
GD-Series Motorized Rollers
Brushless DC motor-driven rollers with integral gearboxes for gravity-assist conveying. Common faults include encoder misalignment, bearing wear, and PWM controller brownout conditions affecting synchronization across multi-roller lines.
GravityLogic PLC Control System
Modular programmable logic controller for managing roller speed profiles, load sensing, and emergency stop sequencing. Prone to firmware corruption, Ethernet port failures, and analog input module degradation in humid Indian factory environments.
GD-SafeMotion Safety Module
Dual-channel safety relay integration for conveyor emergency lockdown and personnel protection. Experiences relay contact erosion, 24VDC supply ripple issues, and diagnostic LED failures in high-vibration mounting locations.
GD-Link Servo Synchronization Drive
High-precision stepper-motor controller for synchronized multi-zone conveyor segments. Suffers from quadrature encoder faults, microstepping resolution loss, and CAN-bus communication timeouts under electrical noise.
GD-PowerStage Inverter Module
3-phase inverter for variable-frequency drive control of heavy-duty gravity roller lines. Typical failures include capacitor bulging, IGBT short-circuit, and gate-driver IC delamination from thermal cycling.

Common GRAVI DRIVE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GRAVI DRIVE equipment arriving at our workshop.
- ✓GD-Series Roller Encoder Drift and Synchronization Loss — GRAVI DRIVE motorized rollers rely on incremental rotary encoders for speed feedback. Vibration, moisture ingress, and misalignment of the encoder hub cause phantom pulses, leading to roller speed discrepancy errors across the conveyor line.
- ✓GravityLogic Firmware Corruption and Boot Loop — Power surges, incomplete firmware updates, and corrupted SD card blocks in GRAVI DRIVE's GravityLogic PLC trigger cyclic boot failures and loss of conveyor logic. Common in Indian facilities with unstable mains voltage.
- ✓GD-PowerStage Capacitor Bulging and Thermal Runaway — GRAVI DRIVE inverter modules use aluminum electrolytic capacitors rated for 105°C. In high-ambient Indian factories (ambient >35°C), repeated thermal cycling causes capacitor rupture and internal impedance rise, reducing filter efficiency and triggering overvoltage shutdown.
- ✓GD-SafeMotion Relay Contact Erosion and Intermittent E-Stop Activation — The dual-channel safety module's relay contacts experience arcing under high-current conveyor load surges. Erosion creates intermittent contact resistance, causing false emergency stop signals and nuisance shutdowns.
- ✓GD-Link Quadrature Encoder Fault and Stepper Microstepping Loss — GRAVI DRIVE's servo synchronization system decodes quadrature encoder phases to apply microstepping correction. EMI from adjacent power cables, loose shielded connectors, and faulty encoder daughterboards cause phase detection errors, collapsing microstepping resolution and causing jerky roller motion.
- ✓GD-Link CAN-Bus Timeout and Multi-Zone Controller Desynchronization — GRAVI DRIVE daisy-chains GD-Link modules via CAN-bus. Bit-rate mismatches, stub cable reflections, and termination resistor faults cause frame collisions and arbitration failures, isolating zones and creating unsynchronized conveyor sections.

Frequently Asked Questions — GRAVI DRIVE Repairs
Do you repair GRAVI DRIVE equipment anywhere in India?+
Yes. Synchronics repairs the complete GRAVI DRIVE product range — motorized rollers, GravityLogic controllers, SafeMotion safety modules, and GD-Link servo systems. We operate PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Jaipur, and all tier-2 industrial cities. Equipment arrives at our Vadodara, Gujarat facility within 48 hours. We maintain GRAVI DRIVE spare parts stock and offer 7-10 day turnaround for most repairs.
What is the typical repair turnaround for GRAVI DRIVE motorized roller encoder faults?+
Encoder replacement and recalibration typically takes 5-7 working days. Synchronics sources GRAVI DRIVE original encoder sensors, aligns the hub using precision jigs, and performs full synchronization testing across a mock conveyor segment before dispatch. Rush repairs (24-48 hours) available for critical production lines at additional cost. We include 6 months warranty on encoder repair.
Can Synchronics recover my GRAVI DRIVE PLC controller if it has firmware corruption?+
Yes. We have JTAG and ISP (In-System Programming) capability for all GravityLogic PLC generations. Our engineers extract corrupted firmware for forensic analysis, rebuild the bootloader, and restore from archived firmware images. If no backup exists, we can program a blank controller with your original logic configuration if documentation is available. Success rate >95% for firmware-only corruption.
Do you offer on-site GRAVI DRIVE repair or only depot service?+
Primarily depot service with rapid turnaround. However, for critical conveyor line failures affecting multiple production zones, Synchronics can dispatch a field engineer to your facility in major Indian metros (Mumbai, Delhi, Bangalore, Chennai, Pune) within 24 hours. Field diagnostics, troubleshooting, and emergency module swap-outs are available. On-site repair rates apply; remote expert support via video call included.
What warranty and documentation do you provide with GRAVI DRIVE repairs?+
All GRAVI DRIVE repairs come with a 12-month parts and labor warranty. Synchronics provides a detailed test report showing pre-repair fault analysis, repair methodology, component-level changes, and post-repair performance benchmarks. You receive the original controller PCB photographs, encoder calibration certificates, and CAN-bus protocol logs if applicable. For compliance tracking, we maintain repair records digitally for 7 years.
How do I send my GRAVI DRIVE 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 GRAVI DRIVE 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 GRAVI DRIVE 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 GRAVI DRIVE 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.
