Multi-Axis Drive & Coordinated Drive System Repair
Component-level repair for multi-axis servo systems, gantry drives, coordinated drive trains, multi-motor VFD panels, and synchronised printing or packaging machine drive systems. All major brands. Pan India.
In a multi-axis system, one failed drive stops every axis. Synchronics repairs individual servo amplifiers, common DC bus multi-axis systems, gantry drive pairs, and complete coordinated drive panels at the component level — restoring full axis synchronisation and drive system integrity.
Modern CNC machining centres, printing presses, packaging lines, textile machines, and robotic welding cells use multi-axis drive systems where every servo amplifier must operate in precise synchronisation. A single failed axis drive in a 5-axis CNC machining centre halts the entire cell. A drive fault in one print unit of an 8-colour offset press stops the whole press. A gantry drive imbalance on a large portal machine triggers an e-stop. Synchronics specialises in the repair of these coordinated multi-axis drive systems — understanding not just the individual drive failure, but the system-level implications of axis interdependence, common DC bus architecture, master-follower synchronisation, and fieldbus coordination. We repair individual axis drives, common DC bus power supply units, axis controller boards, motion controller cards, and complete multi-drive panels at component level.
Diagnosis Guide
Common Multi-Axis Drive & Coordinated Drive System Problems We Fix
Experiencing any of these symptoms? Our engineers have diagnosed and repaired thousands of these faults.
Single Axis Fault Stops Entire System
One axis shows drive fault alarm — entire multi-axis cell, gantry, or CNC stops. Cannot operate remaining axes without the failed axis.
IGBT failure on one servo amplifier, encoder feedback loss on one axis, DC bus fault on common bus system
Gantry Axis Synchronisation Error
Gantry machine shows axis sync error, mechanical binding, position deviation alarm between master and follower axis
One gantry drive has different gain or lag after maintenance, encoder feedback mismatch between axes, one drive repaired with different firmware version
Common DC Bus Fault
Entire multi-axis system loses power — all axes fault out simultaneously, common bus voltage drops to zero
Rectifier unit failure, common bus capacitor bank failure, bus fuse blown from individual axis fault cascade
Fieldbus Communication Loss
Motion controller reports axis communication lost, axes fault on communication timeout, machine goes into safe state
EtherCAT or SERCOS interface card failure on one axis amplifier breaks daisy-chain communication to all downstream axes
Speed Ratio Mismatch on Multi-Motor Line
Speed ratio between sections drifts — material tension changes, web breaks, product dimension errors
One VFD in a multi-drive speed-ratio group has different slip compensation or encoder calibration after repair or replacement
Position Loop Instability After Drive Repair
Axis hunts or oscillates after drive repair or replacement, position overshoot, vibration at standstill
Current loop or speed loop gains not matched between old and new drive, encoder phasing reversed, inertia settings not configured for motor
How It Works
Our Multi-Axis Drive Repair Process
A systematic, schematic-driven repair process — from receipt to dispatch.
System Documentation
Before removing any drive from a multi-axis system, document all axis parameters, drive configuration, fieldbus addresses, encoder phasing, and synchronisation settings. This is critical — without it, re-commissioning can take days. We provide a parameter documentation checklist.
Safe Removal of Failed Axis
In common DC bus systems, other axes must be safely inhibited before removing the failed axis. We provide detailed safe removal instructions specific to your drive architecture to prevent damage to remaining drives.
Individual Drive Diagnosis
Failed drive diagnosed on isolated bench — IGBT gate characterisation, DC bus check, control board boot, encoder interface signal quality, and fieldbus communication port test. Root cause identified and quoted.
Component-Level Repair
Component-level repair from our 2M+ inventory — IGBT modules, gate driver ICs, encoder interface components, DSP and FPGA devices, EtherCAT and SERCOS interface ICs, and fieldbus transceivers for all major multi-axis architectures.
Axis Performance Matching
For gantry pairs and synchronised axis groups, we verify the repaired drive matches the performance of the remaining axes — current loop bandwidth, speed loop gain, encoder delay — to prevent synchronisation issues on reinstallation.
Return & Commissioning Support
Repaired drive returned with full documentation of settings, repair report, and 6-month warranty. Remote telephone support available during reinstallation and recommissioning to verify axis synchronisation and motion controller re-integration.
Thorough Inspection
What We Check in Every Multi-Axis Drive
Every unit goes through a comprehensive inspection checklist before and after repair.

The Synchronics Advantage
Why Choose Us for Multi-Axis Drive & Coordinated Drive System Repair
System-Level Understanding
We repair the individual drive and understand its role in the complete multi-axis system — common DC bus architecture, gantry synchronisation, master-follower relationships, and fieldbus topology. This prevents the commissioning problems that occur when only the component failure is addressed.
Parameter Documentation Support
We provide axis parameter documentation checklists for all major multi-axis systems — helping your maintenance team capture the correct settings before removal, ensuring correct configuration on reinstallation without OEM re-commissioning.

FAQ
Frequently Asked Questions
Yes. We repair individual servo amplifiers from multi-axis systems routinely. The critical requirement is that you document all axis parameters before removal — we provide a checklist for this. We test the repaired axis on our servo test bench and return it with full performance documentation for reinstallation.
Gantry drives must be matched in performance — if one drive is repaired with different gain characteristics, mechanical binding or synchronisation errors will occur. We recommend sending gantry axis pairs together so we can verify matched performance between master and follower. If only one axis failed, we will match the repaired drive parameters to the data from the remaining axis.
Yes. Siemens SINAMICS S120 booksize and chassis format multi-axis systems are one of our most common repairs. We repair individual motor modules, the common line module (ALM), the active interface module, and the control unit (CU320/CU310) at component level.
We support all major multi-axis fieldbus protocols — EtherCAT, SERCOS II/III, MECHATROLINK-II/III, Profibus, Profinet, EtherNet/IP, and DeviceNet. We test fieldbus interface ICs and fibre optic links as part of every multi-axis drive repair.
Yes. We provide telephone commissioning support during reinstallation and re-commissioning — axis enable sequence, encoder phasing verification, current loop commissioning, and synchronisation verification. This is included with every multi-axis drive repair at no extra charge.
