GANTRY Product Lines We Repair
Our engineers are trained on the full GANTRY product range. Below are the major product families we service.
GANTRY Portal Robots (GR / GRX)
Modular 3-axis and 4-axis portal gantry systems with servo or stepper actuation. Common faults include servo loop oscillation, encoder drift, and home-cycle timeouts causing positioning errors and repeatability loss.
GANTRY Motion Control Boards (MCB Series)
Standalone and modular stepper/servo driver boards with step-direction or analog input interfaces. Repair challenges include power stage failures, encoder signal loss, and oscillator faults causing axis runaway or stall errors.
GANTRY Linear Actuators & Ballscrew Assemblies
Precision ballscrew stages with integrated stepper or servo motors, coupling and bearing units. Typical issues: backlash wear, bearing preload loss, stepper detent errors, and sealing degradation from thermal cycling.
GANTRY PLC & Synchronization Modules (GSM)
Embedded controllers for multi-axis gantry synchronization, encoder feedback processing, and safety interlocks. Common failures: firmware corruption, analog input scaling drift, CAN bus communication loss, and watchdog timer resets.
GANTRY Encoder Interface Cards (EIC)
Differential SSI, CANopen, and EnDat encoder signal conditioning modules for closed-loop servo and stepper feedback. Repair needs: signal buffer failures, power supply decoupling issues, protocol decoder faults causing axis hunting.
GANTRY Stepper Driver Modules (SDM)
Microstepping drivers with current limiting, stall detection, and temperature monitoring. Common defects: MOSFET burnout, PWM frequency instability, thermal shutdown cycling, and phase detection faults.

Common GANTRY Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GANTRY equipment arriving at our workshop.
- ✓Servo oscillation and hunting on GANTRY axes — Proportional-Integral (PI) loop gains incorrectly tuned during integration, encoder noise coupling, or mechanical backlash exceeding servo bandwidth. GANTRY servo drives expect deadband settings in the 0.5-2.0 encoder count range; excessive deadband masks real errors.
- ✓Home cycle timeout and lost zero reference — Home sensor (proximity or opto-interrupter) signal dropout, GANTRY MCB encoder latch not triggering at index pulse, or stepper motor stall during homing speed ramp. Debris or bearing wear can cause intermittent sensor activation.
- ✓Encoder signal loss and CRC errors on GANTRY GSM modules — Differential signal cable shielding degradation, termination resistor failure on SSI or CANopen network, or encoder power supply brownout. GANTRY encoders draw 200-500mA; undersized supply leads to intermittent data corruption.
- ✓Stepper driver MOSFET failures and phase short circuits — Excessive back-EMF during rapid deceleration or stall condition, inadequate heatsinking in high-ambient (>50C) industrial environment, or firmware underflow/overflow in PWM counter causing gate drive faults. GANTRY SDM modules operate at 20-40kHz switching; thermal runaway is common.
- ✓Multi-axis synchronization drift on 4-axis gantry platforms — Mechanical wear in ballscrew assemblies on different axes, servo tuning mismatch between axes, or GANTRY GSM synchronization module losing encoder pulse count due to EMI or supply noise. Payload imbalance accelerates differential wear.
- ✓PLC watchdog timeout and intermittent axis lockup — Firmware infinite loop in GANTRY GSM main routine, interrupt priority inversion blocking motion update cycle, or CAN bus communication congestion preventing timely encoder feedback processing. Watchdog period typically 50-100ms on GANTRY controllers.

Frequently Asked Questions — GANTRY Repairs
Do you repair GANTRY equipment anywhere in India?+
Yes. Synchronics repairs the complete GANTRY product range — portal robots, motion control boards, stepper drivers, servo modules, PLC synchronization controllers, and encoder interface cards. We offer PAN India door-to-door pickup and repair from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all tier-2 cities. All repairs are handled at our factory-certified facility in Vadodara, Gujarat with turnaround time of 7-14 days.
How do you handle GANTRY servo tuning during repair?+
GANTRY servo tuning is not a DIY task. Our engineers use instrumented step-response testing with real ballscrew loads and encoder feedback to establish P-I loop gains. We maintain GANTRY commissioning manuals and servo tuning tables for each portal robot model. After repair, every servo axis is validated on our motion test rig before shipment. We provide detailed tuning parameter documentation so your plant engineers can replicate settings if needed.
What is the typical cost and timeline for GANTRY gantry system repair?+
Repair costs vary: GANTRY stepper drivers (SDM series) typically cost Rs 4,000-8,000 per unit; servo boards (MCB-Servo-Pro) Rs 8,000-15,000; PLC modules (GSM) Rs 12,000-20,000; and full portal robot diagnosis Rs 5,000-8,000. Most repairs complete in 5-7 working days. Emergency same-facility expedited repair is available for automotive and semiconductor lines with additional premium. We offer 6-month warranty on all GANTRY component repairs.
Can Synchronics calibrate GANTRY encoder modules and verify positioning repeatability?+
Yes. Synchronics owns precision calibration equipment including encoder simulation sources and ballscrew runout gauges certified to ±0.01mm. We perform full encoder interface validation on GANTRY EIC modules using differential signal injection and protocol loopback testing. After repair, gantry repeatability is certified using our motion test stand fitted with dial indicators and laser position verification to ±0.05mm accuracy.
Do you stock GANTRY spare parts for faster turnaround?+
Synchronics maintains active inventory of common GANTRY stepper drivers (SDM-1A, SDM-3A), encoder interface boards (EIC-SSI, EIC-CANopen), and motion control modules (MCB-2A, MCB-4A). We also stock OEM-equivalent MOSFET sets, thermistors, and power connectors for on-the-spot component replacement. Customers can request spare parts list for their specific GANTRY gantry configuration to expedite ordering.
How do I send my GANTRY 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 GANTRY 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 GANTRY 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 GANTRY 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.
