BOLDENS Product Lines We Repair
Our engineers are trained on the full BOLDENS product range. Below are the major product families we service.
Boldens SM Series Stepper Motors & Drivers
NEMA and IEC stepper motor systems with integrated stepping drivers. Common failures include driver IC burnout, encoder signal loss, coil phase faults, and microstepping algorithm errors. Temperature-induced calibration drift affects positioning accuracy in textile and packaging applications.
Boldens AC Servo Amplifiers (ACSA Line)
Compact servo amplifiers for AC brushless motor control with integrated resolver/encoder feedback. Repair requires expertise in current loop tuning, commutation timing adjustment, and hall sensor calibration. Common faults: capacitor bank degradation, MOSFET gate driver failures, and feedback circuit noise susceptibility.
Boldens PLC Compact Controllers (CC Series)
Modular PLC platforms for process automation in pharmaceutical, food, and chemical plants. Ethernet port failures, memory corruption, and input/output card failures are frequent repair items. Synchronics restores logic execution, analog I/O accuracy, and network connectivity.
Boldens HMI Operator Panels (OP-Touch Range)
7-15 inch industrial touch screen interfaces with Ethernet and serial connectivity. Screen backlight failure, capacitive touch sensor malfunction, and communication bus errors common in high-humidity environments. EEPROM data recovery and firmware restoration specialised at Synchronics.
Boldens DC Thyristor Controllers (TC Series)
Industrial DC motor speed and torque controllers for legacy Indian textile, steel, and paper mills. Thyristor gate circuit failures, snubber capacitor degradation, and rectifier bridge faults typical. Synchronics performs gate driver replacement, pulse transformer testing, and closed-loop feedback calibration.
Boldens Encoders & Feedback Modules (ENC Series)
Incremental and absolute encoders with SSI, CANopen, and analog output variants. Housing water ingress causes bearing seal failure and electrical contact corrosion. Synchronics disassembles, cleans optical/magnetic sensing elements, and recalibrates output linearity.

Common BOLDENS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BOLDENS equipment arriving at our workshop.
- ✓Boldens servo amplifier MOSFET shoot-through failure — Hall sensor signal noise or dead-time mistuning in commutation logic causes simultaneous high/low side MOSFET conduction, thermally destroying the power stage within seconds. Common in plants with poor cable shielding or long motor leads.
- ✓Boldens stepper driver microstepping angle error accumulation — EEPROM calibration data corruption or DAC offset drift in current reference circuit causes stepper to skip microsteps intermittently, leading to dimensional errors in CNC and textile machinery. Environmental temperature swings worsen the fault.
- ✓Boldens PLC Ethernet port intermittent connectivity and packet loss — RJ45 connector corrosion, transformer coil fracture in isolated gate driver, or PHY chip thermal fatigue causes frame drops and PROFINET/Modbus TCP timeouts. Critical in pharmaceutical batch traceability systems.
- ✓Boldens HMI touch screen unresponsiveness and ghost touches — Capacitive touch controller IC calibration table corruption or display backlight driver bootstrap capacitor failure causes erratic or no touch response. Humidity and mechanical stress accelerate the fault in textile and food plants.
- ✓Boldens DC thyristor controller gate pulse loss and uncontrolled motor speed — Pulse transformer primary winding inter-turn short or gate driver opto-coupler LED degradation causes weak or missing gate signals, risking motor runaway and machine damage. Common in high-ambient-temperature foundries.
- ✓Boldens encoder absolute position readout incorrect and SSI/CANopen transmission errors — Magnetic sensing element misalignment, EEPROM position offset table corruption, or communication protocol parser firmware bug causes position jumps or invalid data frames to controller, halting automated assembly lines.

Frequently Asked Questions — BOLDENS Repairs
Do you repair Boldens equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full Boldens product range — servo amplifiers, stepper drivers, PLC controllers, HMI panels, and encoder feedback modules. We offer PAN-India door pickup from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Kolkata, and all other industrial cities. All repairs are processed at our Vadodara facility with 5-10 day turnaround for most faults. Emergency same-day shipping available for critical production stoppages.
What is the typical lead time to repair my Boldens servo amplifier or PLC controller?+
Standard repair turnaround is 5-10 working days including diagnostics, component replacement, firmware reload, and functional testing. We keep common spare parts (MOSFETs, capacitors, optocouplers, connectors) in stock. For critical downtime situations, Synchronics offers 24-48 hour express repair with priority bench allocation. Regional service via Pune and Hyderabad offices can be faster for south and west India.
Do you stock original Boldens spare parts and firmware?+
Synchronics maintains a curated inventory of high-reliability replacement components (power semiconductors, capacitors, transformers, optical sensors) compatible with Boldens designs. For Boldens firmware, we work with authorised distributors in India and Europe to obtain genuine code repositories. We do NOT recommend third-party cloned firmware; instead, we reprogram using official Boldens tools to preserve functionality and warranty integrity. All replaced modules are documented and certified with repair certificates.
My Boldens stepper driver shows ERR-42 code and motors lose steps — is it repairable?+
ERR-42 on Boldens SM-series steppers typically indicates microstepping calibration failure or EEPROM corruption. This is fully repairable. Synchronics extracts calibration data, identifies the root cause (thermal drift, voltage surge, or firmware glitch), repairs the circuit, and recalibrates against factory reference standards. We test across temperature extremes to confirm permanent fix. Most ERR-42 faults return to service within 7 days.
Can Synchronics help with Boldens controller programming and commissioning after repair?+
Yes. After repair completion, Synchronics can assist with firmware reload, parameter configuration, and hardware-software integration testing. However, application-specific logic programming (ladder logic, function blocks) is your responsibility. We recommend engaging your Boldens equipment integrator or in-house automation engineer for final system commissioning. Synchronics provides detailed repair reports and test data to support your commissioning team.
How do I send my BOLDENS 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 BOLDENS 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 BOLDENS 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 BOLDENS 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.
