SIEB & MEYER Product Lines We Repair
Our engineers are trained on the full SIEB & MEYER product range. Below are the major product families we service.
SIMODRV Spindle Drive Series
High-precision AC spindle drives for machine tools and textile machinery. Common faults include power stage failures, encoder communication loss, and thermal runaway under sustained high-speed operation. Synchronics specializes in IGBT replacement, firmware reset, and speed sensor recalibration.
DRIVEPAK Frequency Converter Series
Three-phase frequency converters for motors up to 250 kW. Failures typically involve capacitor bank degradation, cooling fan malfunction, and PLC communication errors. Synchronics replaces electrolytic capacitors, repairs PCB trace damage, and restores RS485 interfaces.
MICRODRIV Compact Drive Controllers
Lightweight PWM converters for servo motors and stepper systems in textile looms and printing presses. Prone to solder joint fatigue, output relay sticking, and firmware corruption. Synchronics performs reflow soldering, relay replacement, and EPROM reprogramming.
SIMOREG DC Master Power Supply Modules
Regulated DC power supplies for machine tool spindles and electroplating lines. Common failures include transformer core saturation, thyristor short-circuit, and control circuit degradation. Synchronics replaces power stages, rewinds transformers, and recalibrates control electronics.
COMBIDRIV Modular Drive Platforms
Modular stacked drive systems for multi-axis machine tool control. Faults include intermodule communication breakdowns, isolated DC supply failures, and cooling fan bearing wear. Synchronics replaces daughter boards, rebuilds power modules, and performs complete mechanical service.
SPINDLE-NET Distributed Control Interface
Network-based spindle control units for Industry 4.0 integration. Failures involve Ethernet transceiver damage, firmware corruption, and parameter memory loss. Synchronics repairs network layers, restores parameter backups, and updates to latest firmware versions.

Common SIEB & MEYER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SIEB & MEYER equipment arriving at our workshop.
- ✓SIMODRV spindle drive power stage failure — Thermal stress from sustained high-speed operation (above 12,000 RPM) or inadequate cooling duct maintenance causes IGBT junction temperature to exceed safe limits, leading to gate-drive circuit collapse and drive shutdown. Indian textile mills operating 16-20 hours daily face accelerated IGBT aging.
- ✓DRIVEPAK capacitor bank bulging and leakage — Electrolytic capacitors in the DC bus accumulate moisture and experience voltage ripple stress in Indian industrial environments with high ambient temperatures and humidity. Capacitor ESR increases, causing converter inefficiency and thermal runaway.
- ✓MICRODRIV PWM output relay malfunction and arcing — Mechanical wear of relay contacts combined with inductive kickback from motor windings causes contact pitting and arc erosion. SIEB & MEYER relay contacts are rated 40A @ 480V AC, but Indian machine shop environments with dusty conditions accelerate wear.
- ✓SIMOREG DC Master transformer primary winding insulation failure — Sustained overload current (>110% rated current) combined with inadequate forced-air cooling causes transformer core and primary coil temperature to exceed 120°C. Insulation breakdown occurs between primary and secondary windings, causing DC output short-circuit and control circuit faults.
- ✓COMBIDRIV intermodule communication timeout error (E-COMBUS fault) — Loose terminal connections between stacked drive modules, vibration-induced ribbon cable disconnection, or corrupt module firmware causes CAN/PROFIBUS message loss. Multi-axis machine tools in vibration-prone environments (punch presses, grinding centers) are particularly affected.
- ✓SPINDLE-NET Ethernet PHY layer communication loss — Industrial Ethernet port surge damage from lightning strikes or switching transients, failed magnetics in the RJ45 connector, and corrupted network stack firmware cause the drive to become unreachable on the machine control network. Indian plants in monsoon-prone regions experience seasonal surge failures.

Frequently Asked Questions — SIEB & MEYER Repairs
Do you repair SIEB & MEYER equipment anywhere in India?+
Yes. Synchronics repairs the full SIEB & MEYER product range—spindle drives, frequency converters, power supplies, servo amplifiers, and modular control platforms. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities. All repairs are handled at our main facility in Vadodara, Gujarat, with guaranteed turnaround of 7-14 days for most failures.
What is the typical repair cost for a SIEB & MEYER SIMODRV 611 spindle drive?+
SIMODRV 611 repair costs depend on fault severity. Power stage replacement (IGBT module) typically ranges INR 18,000-28,000. Complete board failures requiring PCB replacement cost INR 35,000-50,000. We provide a free diagnostic report within 48 hours of receipt, so you know exact costs before repair begins. Synchronics includes 12-month warranty on all repairs and spare parts.
Can Synchronics repair SIEB & MEYER drives with firmware corruption or parameter loss?+
Yes. Synchronics maintains complete SIEB & MEYER firmware archives for all major drive series. We can restore original factory parameters, reprogram custom application logic, and update to the latest firmware versions if available. If you have backed-up configuration files, we can restore those directly. For drives without backups, we restore standard factory defaults and re-commission on your test motor.
How do I know if my SIEB & MEYER drive needs repair versus a simple reset?+
First, try a soft reset: power down the drive for 30 seconds, then power on. If the drive powers up but shows fault codes (E-OVER, E-TEMP, E-SHORT, E-COMBUS), note the code. If the drive remains dead or shows the same fault repeatedly, contact Synchronics. We can often diagnose the issue over phone and advise if it is warranty-valid repair or a quick fix. Always ship the drive with detailed fault description and last-known settings.
Do you stock spare parts for SIEB & MEYER drives or is everything custom ordered?+
Synchronics stocks critical spare parts including IGBT modules, capacitor banks, relay modules, transformers, and PCB components for the most common SIEB & MEYER series (SIMODRV, DRIVEPAK, MICRODRIV). This allows us to deliver faster repairs. Rare or obsolete components are sourced directly from authorized SIEB & MEYER distributors or equivalent OEM-qualified replacements. We always use genuine parts unless technically equivalent alternatives are approved.
How do I send my SIEB & MEYER 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 SIEB & MEYER 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 SIEB & MEYER 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 SIEB & MEYER 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.
