ICHIKAWA ELECTRIC Product Lines We Repair
Our engineers are trained on the full ICHIKAWA ELECTRIC product range. Below are the major product families we service.
FR-E Series AC Drives
Compact, economical variable frequency drives for standard industrial motor control. Common repair issues include control board failures, capacitor degradation, thermal shutdown faults, and communication module failures under high ambient temperatures typical in Indian factory environments.
FR-D Series High-Performance Drives
Advanced multi-function AC drives with regenerative capabilities for energy recovery. Repairs commonly involve IGBT module replacement, gate driver circuit faults, encoder signal issues, and parameter corruption affecting deceleration braking functionality.
Ichikawa Servo Drive Systems
Precision servo amplifiers and motion controllers for positioning and synchronization tasks in textile, printing, and packaging machinery. Frequent faults include servo loop instability, encoder connection failures, current limiting circuit issues, and phase loss detection errors.
Panel Mount & Operator Interfaces
Control panels, HMI touchscreens, and operator keypads integrated with Ichikawa drive systems. Common defects include display screen backlight failure, membrane button contact wear, communication interface damage, and firmware corruption requiring reconfiguration.
Regenerative Power Units (RPU)
External regenerative braking modules for Ichikawa FR-D series drives enabling energy recovery during deceleration. Repair needs typically involve capacitor bank degradation, reverse voltage damage, heat sink corrosion, and discharge resistor burnout.
Communications & Gateway Modules
Fieldbus adapters and industrial Ethernet modules (Modbus, CANopen, EtherCAT) for Ichikawa drive networked control. Common repair issues include connector oxidation, protocol stack firmware corruption, isolation transformer failures, and optical coupler degradation in humid Indian climates.

Common ICHIKAWA ELECTRIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ICHIKAWA ELECTRIC equipment arriving at our workshop.
- ✓FR-E/FR-D control board capacitor failures and power supply collapse — Electrolytic capacitors degrade rapidly in high-temperature, high-humidity Indian factory conditions, especially near textile mills and foundries. Thermal cycling and vibration accelerate component aging, causing control board voltage regulation failures and drive shutdown.
- ✓IGBT module gate driver circuit malfunction and overcurrent shutdown — Contamination from dust and moisture in mill environments compromises the gate driver IC and isolation circuits. Heavy inductive loads cause voltage transients damaging gate drive optocouplers and bootstrap capacitors, triggering continuous E.OCP (Over Current) fault codes.
- ✓Encoder signal loss and servo loop instability in positioning applications — Textile machinery and printing presses subject servo encoders to mechanical vibration, connector corrosion from moisture and lint, and signal cable breakage near moving parts. Intermittent encoder signals cause servo amplifier oscillation and positioning errors.
- ✓Phase loss detection fault and single-phase line condition response — Indian industrial power distribution commonly experiences voltage imbalance and intermittent phase dropout, especially in smaller mill towns. Ichikawa drives with asymmetric phase loss detection trigger nuisance shutdowns when line voltage imbalance exceeds 3-5% threshold.
- ✓Communication interface failure and Modbus/Ethernet protocol timeout errors — Harsh factory environments introduce electromagnetic noise from welding, induction heating, and large motor starters that corrupts RS-485 Modbus signals. Connector corrosion and cable shield grounding faults prevent reliable fieldbus communication between drive and control system.
- ✓Thermal sensor malfunction and false over-temperature shutdown — Thermistor sensors in Ichikawa drive heatsinks degrade from thermal cycling in dusty Indian factories, often showing open-circuit or out-of-range resistance. Corroded sensor connectors and damaged cable insulation trigger spurious thermal fault codes (E.THM) even when drive temperature is normal.

Frequently Asked Questions — ICHIKAWA ELECTRIC Repairs
Do you repair Ichikawa Electric equipment anywhere in India?+
Yes. Synchronics repairs the complete Ichikawa Electric product range including FR-E and FR-D AC drives, servo amplifiers, motion controllers, regenerative power units, and fieldbus communication modules. We offer PAN India door pickup and delivery service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Indore, and all major industrial cities. All repairs are performed at our main facility in Vadodara, Gujarat with 180+ skilled engineers and full component inventory.
What is the typical turnaround time for Ichikawa Electric drive repair?+
Most Ichikawa AC drive repairs are completed within 5-7 working days from receipt at our Vadodara facility. Routine issues like capacitor replacement, connector repair, and control board cleaning take 2-3 days. Complex faults requiring IGBT module replacement, PCB-level troubleshooting, or firmware reconfiguration take 7-10 days. We provide weekly progress updates and expedited 2-3 day turnaround for critical production equipment subject to additional charges.
Do you have genuine Ichikawa Electric spare parts in stock?+
Synchronics maintains steady stock of common Ichikawa Electric replacement components including electrolytic capacitor banks, IGBT modules, gate driver ICs, thermistors, encoder connectors, and control board assemblies for FR-E and FR-D series drives. We source from authorized Ichikawa Electric distributors in Japan and Singapore. Non-stocked parts are procured within 5-7 business days. We always use OEM-equivalent or Ichikawa-approved components to guarantee drive performance and warranty compliance.
What causes continuous E.OCP and E.THM error codes on Ichikawa FR-D drives in textile mills?+
In dusty mill environments, E.OCP (Over Current Protection) typically results from gate driver contamination or failed optocouplers causing IGBT misfiring, while E.THM faults indicate corroded thermistor sensors. Synchronics diagnoses both faults using bench testing, replaces contaminated gate drivers and thermal sensors, and performs 8-hour burn-in testing under simulated load before returning the drive. We also recommend periodic preventive maintenance including heatsink cleaning every 6-12 months.
Can Synchronics repair Ichikawa servo amplifiers and encoder systems?+
Yes. Our servo specialists routinely repair Ichikawa ISD-P series servo drives, precision motion controllers, and integrated encoder feedback systems. We perform encoder signal diagnostics, servo loop tuning, and gain parameter optimization using dedicated servo test benches. Common repairs include encoder connector replacement, servo amplifier gate driver replacement, and current limiting circuit restoration. Most servo repairs are completed within 7-10 days with full functional testing.
How do I send my ICHIKAWA ELECTRIC 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 ICHIKAWA ELECTRIC 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 ICHIKAWA ELECTRIC 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 ICHIKAWA ELECTRIC 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.
