Common BARDAC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BARDAC equipment arriving at our workshop.
- ✓Stepper drive phase loss detection failure — BARDAC MSC series detects phase imbalance via differential current sensing. When the phase detection comparator IC (typically TL339 or similar) drifts out of tolerance, or sense resistor values shift due to thermal cycling, the drive incorrectly reports phase loss and disables output even with balanced input power.
- ✓Encoder signal integrity loss in servo loop — BARDAC SA servo amplifiers use differential RS-422 encoder inputs. In Indian textile and packaging plants with high EMI from induction motors and welding equipment, common-mode noise couples into encoder lines. Poor shielding, long cable runs, and aged connectors degrade signal quality below the receiver's detection threshold.
- ✓Microstepping resolution dropout and cogging — BARDAC stepper drives use precision current-source DACs to set microstepping currents. Over time, reference voltage regulators (LT1117 variants) or the master DAC develop output ripple or gain error, causing uneven current distribution across substeps. This manifests as audible cogging and position inaccuracy in automated assembly lines.
- ✓Overcurrent latch-off with normal load current — BARDAC drive overcurrent detection compares motor current (via isolated current sense amplifier) to a threshold set by a trimmer potentiometer or EEPROM value. Thermal drift in the current sense amplifier (INA138 or INA139 series) or aging of the threshold reference causes nuisance overcurrent trips at less than rated current.
- ✓Thermal shutdown cycling even under light load — BARDAC servo amplifiers include on-board temperature sensors (NTC thermistor or IC sensor like TMP36). If the sensor is loose, has corroded leads, or if the thermal management interface deteriorated, the temperature reading becomes erratic and triggers shutdown at false temperatures.
- ✓EEPROM corruption and loss of drive configuration — BARDAC programmable motion controllers store parameter tables (current limits, microstepping mode, encoder resolution) in on-board EEPROM. Power supply spikes, data line glitches during in-field parameter updates, or fatigue in EEPROM cells cause bit flips, rendering the drive unable to boot or execute calibration routines.

Frequently Asked Questions — BARDAC Repairs
Do you repair BARDAC equipment anywhere in India?+
Yes. Synchronics Electronics repairs the complete BARDAC product range — stepper drives, servo amplifiers, motion control modules, and programmable motion controllers — across all of India. We offer same-week PAN India door pickup and delivery from our Vadodara headquarters in Gujarat. Express repair turnaround available for critical production lines. Contact us with your BARDAC model and fault code for an instant quote.
Can you repair BARDAC drives without original documentation?+
Absolutely. Our 25+ year archive includes schematics, firmware, and service bulletins for nearly all BARDAC stepper and servo products. Even if you don't have the manual, send us the model number, part number, and a photo of any visible fault codes or symptoms. Synchronics engineers will diagnose and repair it using our reference library. We also document every repair so you get detailed test reports.
What is the typical turnaround time for BARDAC stepper drive repair?+
For standard BARDAC stepper drives (MSC series, SDM series), turnaround is 5-7 working days from receipt. This includes board-level diagnostics, component replacement, microstepping calibration, and comprehensive functional testing. Rush repair for critical production halts can be completed in 48 hours. Servo amplifiers (SA series) typically take 7-10 days due to additional encoder and current-loop verification.
My BARDAC drive shows 'Phase Loss' error but mains power is fine. What's wrong?+
Phase loss detection failure is common in BARDAC MSC and MC series drives operating in older Indian plant facilities with poor power infrastructure. The issue is usually in the differential comparator circuit that monitors input phase balance. Synchronics performs three tests: (1) verify mains voltage balance with a clamp meter, (2) test the drive's phase detection comparator IC in-circuit, and (3) inspect sense resistor networks for thermal drift. In 90% of cases, replacing the comparator IC and recalibrating the sense network resolves the false alarm.
Can you upgrade or reprogram my BARDAC motion controller firmware?+
Yes, if the controller's boot ROM is intact and the EEPROM is accessible. Synchronics can load updated BARDAC firmware versions, modify parameter tables (current limits, encoder resolution, microstepping mode), and customize logic sequences for your specific machine. We maintain a current library of BARDAC loader tools and firmware variants. However, bootloader corruption requires chip-off EEPROM replacement. Always contact us before attempting in-field firmware updates to avoid bricking your controller.
How do I send my BARDAC 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 BARDAC 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 BARDAC 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 BARDAC 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.
