DI-ACRO Product Lines We Repair
Our engineers are trained on the full DI-ACRO product range. Below are the major product families we service.
DI-ACRO Press Brake Controllers
Electro-hydraulic control systems for press brake bending machines. Common issues include solenoid coil failures, proportional valve spool stiction, and PLC processor faults leading to inconsistent bend angles and loss of depth control.
Hydraulic Proportional Valve Electronics
Proportional spool drive modules and feedback amplifiers for DI-ACRO press systems. Failures often manifest as jerky ram motion, inability to hold tonnage, or erratic pressure spikes caused by solenoid shorts or amplifier drift.
DI-ACRO Shear Control Systems
Precision cutting controllers for hydraulic shear machines. Issues include blade gap sensor failures, motor starter relay chattering, and analog-to-digital converter errors causing inconsistent cut quality.
Servo-Hydraulic Bend Systems
Closed-loop servo systems for high-precision bending in aerospace and automotive applications. Typical faults are servo valve coil opens, LVDT position sensor drift, and feedback amplifier oscillation causing poor bend repeatability.
DI-ACRO Legacy Analog Controllers
Older electromechanical and analog electronic control boards for manual and semi-automatic machines. Repairs address capacitor drying, relay pitting, potentiometer wear, and transformer core saturation.

Common DI-ACRO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DI-ACRO equipment arriving at our workshop.
- ✓Proportional solenoid coil open or shorted — DI-ACRO proportional valve coils fail due to moisture ingress in hydraulic environment, contaminated hydraulic fluid causing abrasion, or voltage spikes from unshielded wiring. Shorted turns reduce coil inductance and prevent full spool displacement.
- ✓Loss of bend depth accuracy and reproducibility — LVDT position transducers in DI-ACRO controllers drift over time due to temperature cycling and vibration. Feedback amplifier gain shifts or offset errors accumulate, causing the closed-loop system to overshoot or undershoot target bend depths by 0.5-2mm per bend cycle.
- ✓Hydraulic ram extends but does not retract smoothly — Proportional pilot spool in DI-ACRO valve systems sticks due to varnish buildup from degraded hydraulic oil or particulate contamination. Return spring corrosion or bent spool rod also restricts motion, causing jerky retraction and pressure spikes.
- ✓Controller displays fault code or loses operator input — DI-ACRO PLC-based controllers fail when button/switch inputs are read as floating or intermittent due to corroded connectors, broken wiring, or failed input isolation optocouplers. Water ingress near control panel footswitches is common in humid Indian facilities.
- ✓Proportional valve solenoid does not respond to command signal — DI-ACRO solenoid drivers (amplifiers) fail due to gate-driver IC thermal damage, power MOSFET shorts, or feedback network component failure. Inadequate PWM frequency matching between controller and driver also prevents proper solenoid energization.
- ✓Inconsistent cutting edge or shear blade chatter — DI-ACRO shear controllers lose feedback from blade-gap proximity sensors (often inductive) due to sensor fouling by metal chips, corroded sensor leads, or failed sensor amplifier channels. Without feedback, blade gap cannot be maintained, causing uneven cuts.

Frequently Asked Questions — DI-ACRO Repairs
Do you repair DI-ACRO equipment anywhere in India?+
Yes. Synchronics has specialized expertise in DI-ACRO press brake control systems, proportional valve electronics, and servo-hydraulic modules. We provide door-to-door pickup service across India — Mumbai, Delhi, Bangalore, Chennai, Hyderabad, Ahmedabad, Pune, Indore, and beyond. All repairs are completed at our 180+ engineer facility in Vadodara, Gujarat. Typical turnaround is 5-10 working days.
What is the most common DI-ACRO press brake failure we see in Indian shops?+
Proportional solenoid coil failures and hydraulic spool stiction are our two most frequent repairs. Indian plants operating in humid coastal regions (Mumbai, Chennai) and dusty locations (Delhi NCR, Gujarat) see faster solenoid coil degradation due to moisture and contaminated oil. Synchronics recommends annual hydraulic fluid sampling, coil insulation testing, and solenoid preventive maintenance to avoid unplanned downtime.
Can Synchronics calibrate or reprogram a DI-ACRO CNC-7 controller after repair?+
Absolutely. Synchronics has technicians trained on DI-ACRO CNC-7 and legacy analog controllers. After repairs, we perform full calibration — solenoid response linearity, closed-loop gain tuning, and bend-depth repeatability testing. We verify the controller meets original OEM specifications and provide a calibration report. If your machine lost programs, we can help restore settings from your backup or work with your maintenance team to re-enter recipes.
Why does my DI-ACRO press brake lose depth accuracy over months of operation?+
Feedback sensors (LVDT position transducers) in DI-ACRO closed-loop systems gradually drift due to temperature swings, vibration, and cable connector corrosion. Hydraulic fluid degradation also alters proportional valve response, shifting the bend-depth calibration. Synchronics recommends routine annual transducer calibration, connector inspection, and fluid analysis for shops running heavy daily cycle counts. Many customers schedule preventive recalibration during scheduled shutdowns.
What warranty does Synchronics offer on DI-ACRO repairs?+
All DI-ACRO control board and electronics repairs carry a 12-month warranty against defects in material or workmanship. Hydraulic valve repairs include a 6-month warranty on rewind work and replaced seals. We recommend extending preventive maintenance intervals and fluid sampling to protect your warranty and maximize equipment life. Please contact our service team for specific warranty details on your equipment model.
How do I send my DI-ACRO 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 DI-ACRO 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 DI-ACRO 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 DI-ACRO 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.
