DYNICS Product Lines We Repair
Our engineers are trained on the full DYNICS product range. Below are the major product families we service.
DYNICS Brushless Servo Drives
High-torque servo controllers for precision positioning in textile looms, packaging machinery, and CNC systems. Common issues include encoder communication loss, thermal runaway, and PWM stage failures affecting closed-loop feedback accuracy.
DYNICS Stepper Motor Drivers
Microstepping controllers for printing machinery, labeling systems, and small-scale automation. Repair focus: phase coil shorts, step-loss under load, and current regulation IC failures causing stalled motors.
DYNICS AC Variable Frequency Drives
Compact VFDs (0.5-37kW) for pump motors, fan drives, and conveyor systems in Indian sugar, cement, and food processing plants. Typical faults: DC bus capacitor ripple, IGBT module delamination, and EMI filter saturation.
DYNICS Motion Control Modules (MCM)
Networked motion controllers with Modbus/Ethernet for multi-axis synchronization in textile and printing equipment. Common repairs: EEPROM corruption, isolated CAN transceiver failure, and firmware bootloader reset.
DYNICS Encoder Interface Boards
Incremental and absolute encoder signal conditioning for servo feedback loops. Repair challenges: ESD damage to input buffers, signal integrity under electromagnetic noise, and counter IC bit-slip.
DYNICS Gate Driver Modules
Isolated high-current MOSFET/IGBT drivers for three-phase inverter stages. Failure modes: shoot-through from gate delay mismatch, demagnetization of coupling transformers, and bootstrap capacitor ESR increase.

Common DYNICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DYNICS equipment arriving at our workshop.
- ✓DYNICS servo drive encoder communication timeout — DYNICS incremental encoder connectors suffer oxidation and loose shielding in humid Indian factory environments, causing intermittent signal dropout. EMI from nearby welding or power switching also couples into encoder twisted pairs, inducing CRC errors in feedback interpretation.
- ✓Brownout-induced DYNICS drive lockout and soft reset loop — Indian power grids experience brownouts (50-100ms sags below 180V AC) that collapse the DYNICS DC bus below the watchdog threshold. The drive enters safe state, loses synchronization with load, then re-attempts startup—trapping the motor in a stalled, overheating cycle.
- ✓DYNICS DC bus capacitor ESR rise and ripple voltage failure — Aluminum electrolytic capacitors in DYNICS drives degrade under high ambient temperature (40-50°C in Indian plants) and continuous switching current. After 3-5 years, ESR increases 2-3x, raising ripple voltage and destabilizing the PWM feedback loop, triggering 'Bus Voltage Unstable' faults.
- ✓DYNICS stepper motor phase coil short and microstep loss — Abrasive dust ingress in textile mills creates conductive paths across phase windings in DYNICS stepper drivers. Short-circuit path reduces phase inductance, causing current collapse during microstepping and erratic stall torque, leading to repeated step-loss on high-speed printing systems.
- ✓DYNICS IGBT gate driver saturation and thermal runaway — DYNICS PWM frequency ramping or weak gate drive impedance (high source resistance) under heavy load causes IGBT Miller charge buildup. Gate voltage sags below threshold, increasing IGBT on-state voltage drop and junction temperature, triggering thermal shutdown—but thermal latch prevents restart until cold-soaked.
- ✓DYNICS motion controller EEPROM data corruption and bootloader failure — Power interruption during DYNICS firmware upload or MCM parameter write creates incomplete EEPROM pages, causing checksum mismatch. Bootloader enters safe mode and halts—drive becomes non-responsive to Modbus/Ethernet commands and cannot be remotely recovered.

Frequently Asked Questions — DYNICS Repairs
Do you repair DYNICS equipment anywhere in India?+
Yes. Synchronics repairs the full DYNICS product range — servo drives, stepper controllers, VFDs, motion control modules, and encoder interface boards across all Indian industrial sectors. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Bangalore, Kolkata, and all other cities. All repairs are conducted in our ISO-certified facility in Vadodara, Gujarat. Typical turnaround is 5-7 working days, with express 48-hour repair available for critical production stops.
What is the typical cost and warranty for DYNICS drive repair?+
DYNICS servo and stepper drive repairs typically cost 35-60% of replacement equipment cost, depending on fault complexity and component availability. Synchronics offers 12-month warranty on all repairs covering parts and labor, with 30-day money-back guarantee if the drive does not restore to factory performance. We provide detailed test reports and performance benchmarking data so you can verify repair quality before accepting the unit.
How do I know if my DYNICS drive has a repairable fault or is beyond economical repair?+
Synchronics provides free fault diagnosis for DYNICS equipment. We test encoder feedback integrity, DC bus voltage ripple, gate drive signals, and firmware/EEPROM checksums. If multiple power stage IGBTs are shorted or the microcontroller is physically damaged, we advise replacement. However, 85-90% of DYNICS faults we receive are repairable — capacitor replacement, gate driver IC swap, firmware reload, or connector re-termination. We always quote repair cost upfront and get written approval before proceeding.
Can Synchronics repair DYNICS drives if I do not have the original parameter backup or documentation?+
Yes. Synchronics maintains a library of DYNICS factory default firmware images and parameter sets for stepper, servo, and VFD series spanning 2005-present. If your drive EEPROM is readable, we extract and analyze the configuration. If EEPROM is corrupt, we restore factory defaults and guide you to reprogram application-specific parameters (ramp time, acceleration, current limits) based on your machine nameplate or operating manual. For unusual DYNICS custom configurations, we work with your process engineer to reverse-engineer safe startup values.
Does Synchronics offer DYNICS preventive maintenance or lifetime monitoring services?+
Yes. Synchronics offers DYNICS equipment health monitoring through periodic capacitor ESR/ripple testing, IGBT leakage current trending, and firmware log analysis. We can schedule annual or bi-annual bench testing to identify aging components (like DC bus capacitors) before they fail. For critical production lines using DYNICS drives, we offer on-site condition monitoring and predictive replacement planning to avoid unplanned downtime. Contact our service team for a customized maintenance contract for your DYNICS installation.
How do I send my DYNICS 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 DYNICS 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 DYNICS 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 DYNICS 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.
