DAISAN Product Lines We Repair
Our engineers are trained on the full DAISAN product range. Below are the major product families we service.
DAISAN Servo Motors (AC/DC)
Compact AC and DC servo motors rated 50W to 3kW with integrated encoders. Common repair issues include encoder degradation, winding insulation breakdown under humid conditions, bearing wear causing vibration noise, and rotor imbalance in high-speed applications exceeding 3000 RPM.
DAISAN Motion Controllers (Standalone)
Single-axis and multi-axis motion control boards featuring pulse-direction or analog inputs. Repair demand includes firmware corruption, input/output relay failures, capacitor swelling in 50°C+ environments, and communication port damage from industrial noise coupling.
DAISAN Stepper Motor Drivers
Embedded stepper drivers for NEMA 17-42 frame motors, commonly found in textile and packaging machinery. Failures include power MOSFET burnout under load spikes, microcontroller flash memory corruption, and thermal shutdown sensor malfunction in non-air-conditioned mill floors.
DAISAN Servo Amplifiers
Compact amplifiers for servo motor feedback control with ±10V or 0-10V command inputs. Typical faults include output stage short circuits, feedback loop instability, and connector pin corrosion in high-humidity textile mills and dye houses.
DAISAN PID Motion Modules
Embedded PID tuning modules integrated into machinery control cabinets. Common issues are algorithm drift under temperature extremes, oscillation loop stability problems, and parameter memory loss after power cycling.
DAISAN Spindle Speed Controllers
Specialized controllers for lathe and CNC spindle motors with electronic braking. Repair issues include power bridge component failure, speed feedback sensor malfunction, and emergency stop relay sticking in dusty machine shops.

Common DAISAN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DAISAN equipment arriving at our workshop.
- ✓Servo motor encoder failure and zero-position loss — DAISAN encoders use optical or magnetic sensors exposed to spindle coolant mist and machine tool vibration. Oil contamination on encoder windows and bearing friction cause position drift, leading to lost home reference and axis runaway errors. Common in Indian CNC and textile machinery operating 16-24 hours daily.
- ✓DMC motion controller firmware corruption and bootloader hang — DAISAN DMC controllers store motion profiles in onboard flash memory vulnerable to power supply ripple and ESD spikes. Voltage sags during grid brown-outs common in Indian industrial areas trigger incomplete firmware writes, leaving the controller in bootloader mode unable to execute stored machine sequences.
- ✓Stepper driver MOSFET burnout and phase lock-up — DAISAN DSD drivers used in textile spindle drive systems experience current spikes when load increases suddenly (e.g., thread jam or yarn snag). Indian power quality issues with harmonic distortion from nearby welding equipment increase thermal stress, causing output stage MOSFETs to short and lock the stepper motor.
- ✓Servo amplifier feedback loop instability and oscillation — DAISAN servo amplifiers tuned at the factory for laboratory loads become unstable when installed on Indian machines with mechanical play, belt stretch, or worn spindle bearings. High-frequency oscillation in the feedback path causes heating, audible whining, and eventual capacitor failure.
- ✓Motion controller input/output relay chatter and contact wear — DAISAN DMC controllers use electromechanical relays for spindle start/stop, brake engagement, and alarm outputs. Vibration from heavy machinery, lightning strikes on nearby power lines, and switching transients cause contact erosion. Indian industrial environments with poor grounding see contact arcing every few thousand cycles.
- ✓Connector pin corrosion and intermittent signal loss — DAISAN equipment deployed in Indian dye houses, chemical plants, and humid coastal facilities experience salt-air and chemical vapor exposure. Brass and tin-plated connector pins oxidize green, causing high contact resistance and intermittent axis faults that appear random to the machine operator.

Yes. Synchronics repairs the full DAISAN product range — servo motors, motion controllers, stepper drivers, amplifiers, PID modules, and spindle controllers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Bengaluru, and all other major cities. Single repair facility in Vadodara, Gujarat with 180+ engineers and 28 years experience on Japanese precision equipment.
What is the typical repair time for a DAISAN servo motor or motion controller?+
Standard turnaround is 3-5 business days from receipt. Servo motor diagnosis, bearing replacement, and encoder realignment typically take 2 days. Motion controller firmware reprogramming and relay replacement take 1-2 days. Rush service available at 25% surcharge. We provide daily email updates on complex repairs. Shipping time not included — express courier available.
Can you repair DAISAN servo encoders and provide zero-position re-calibration?+
Yes. DAISAN encoders (optical and magnetic types) are our specialty. We clean, inspect, and recalibrate zero position offsets using precision jigs matching DAISAN factory specifications. For absolute encoders, we validate the position word after reassembly. Optical encoders receive protective conformal coating to resist coolant mist. Cost is typically Rs 8,000-15,000 including labour and materials.
Do you have spare parts inventory for DAISAN equipment, or do you use refurbished components?+
We stock original DAISAN components for high-failure items: servo motor bearings, encoder discs, relay coils, and output MOSFETs. For obsolete parts (discontinued models), we source compatible alternatives tested for electrical and mechanical compatibility. All refurbished modules undergo full burn-in testing. New OEM parts ordered on request if customer requires warranty assurance. Bill of Materials provided with every repair.
Do you provide load-testing and performance certification for repaired DAISAN drives and controllers?+
Yes. After repair, all DAISAN equipment undergoes parametric testing: servo motors spun under 150% rated load for 2 hours, motion controllers run 10,000 command cycles with scope-verified output timing, stepper drivers tested at rated current with thermal camera monitoring. Load-test data and oscilloscope waveforms provided in repair report. Optional third-party calibration certificate available for food/pharma compliance.
How do I send my DAISAN 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 DAISAN 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 DAISAN 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 DAISAN 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.
