CINCINNATI DYNACOMP Product Lines We Repair
Our engineers are trained on the full CINCINNATI DYNACOMP product range. Below are the major product families we service.
Dynacomp CNC Control Systems
Industrial-grade CNC controllers for multi-axis machining centers and turning centers. Common repairs include burned servo amplifier modules, logic board faults, analog servo feedback signal loss, and memory corruption affecting machine positioning accuracy.
Proportional Solenoid Valve Drivers
Analog driver boards controlling hydraulic proportional solenoids for spindle feed, coolant flow, and work-holding. Failures include saturated output transistors, precision command signal drift, and proportional spool positioning instability.
Servo Amplifier Modules
Analog servo amplifiers for AC servo motor drive and brush DC servo positioning. Typical faults: thermal runway due to bias network drift, output coupling capacitor drying, closed-loop gain instability, and analog feedback linearization errors.
Hydraulic Pressure Control Modules
Closed-loop pressure regulation electronics for machine hydraulic systems. Repair needs stem from transducer signal conditioning faults, proportional valve command instability, pressure oscillations, and analog filter network deterioration.
Tool Changer and Automation Control Boards
Relay logic and early solid-state control boards for automatic tool changers, part clamping, and work-holding sequencing. Common issues: relay contact welding, solenoid driver burnout, timing circuit oscillation, and interlocking circuit malfunction.

Common CINCINNATI DYNACOMP Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CINCINNATI DYNACOMP equipment arriving at our workshop.
- ✓Servo amplifier thermal runaway and output stage burnout — Cincinnati Dynacomp servo modules use Class AB bias networks that drift with component aging. Thermistor biasing circuits fail, causing bias current to increase, leading to unchecked thermal dissipation and catastrophic output transistor failure.
- ✓Proportional solenoid driver output transistor saturation — Dynacomp proportional valve drivers operate at high current density. Command signal DC offset drift or feedback network failure prevents proper gate biasing, saturating output FETs and eliminating proportional valve modulation control.
- ✓CNC control board logic circuit intermittent faults and memory errors — Cincinnati Dynacomp control boards from 1970s-1980s use fragile 24V logic gates and dynamic RAM that degrade in humid Indian factory conditions. Solder joint fatigue, corroded connectors, and capacitor leakage cause erratic behavior and loss of part programs.
- ✓Analog servo feedback signal distortion and axis positioning errors — Dynacomp machines use precision linear transducers and resolvers for position feedback. Connector corrosion, shielded cable degradation, or op-amp input stage bias current increases cause signal noise and closed-loop instability, resulting in runout and positioning errors.
- ✓Proportional hydraulic valve instability and hunting behavior — Dynacomp proportional valve control loops require precise gain tuning and adequate dampening. Filter network aging, command signal integrity loss, or transducer feedback scaling errors cause the valve spool to oscillate at system resonance frequency.
- ✓Tool changer shuttle and carousel sequencing failures — Cincinnati Dynacomp ATC control boards rely on relay logic and solenoid drivers that wear with repeated cycling. Relay contact pitting, solenoid coil opens, and timing circuit capacitor drying cause timing violations and mechanical jamming.

Frequently Asked Questions — CINCINNATI DYNACOMP Repairs
Do you repair Cincinnati Dynacomp equipment anywhere in India?+
Yes. Synchronics repairs the full Cincinnati Dynacomp product range — CNC controls, servo amplifiers, proportional valve drivers, and automation boards. We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Nashik, and all other industrial cities. All repairs are handled at our facility in Vadodara, Gujarat, with typical turnaround of 5-7 working days for standard faults.
How do I know if my Cincinnati Dynacomp servo amplifier is faulty?+
Common signs: servo axis becomes sluggish or overshoots position commands, excessive vibration during fast feeds, burning smell near the amplifier module, or complete loss of axis motion. Synchronics can perform on-site diagnostics using precision test equipment. We measure servo loop DC offset, output impedance, and bias current to pinpoint the fault before recommending repair or replacement.
Can Synchronics reprogram Cincinnati Dynacomp CNC control boards?+
Yes. We stock EPROM programming equipment compatible with Cincinnati Dynacomp control architectures. If your machine has lost part programs or control parameters, Synchronics can restore original firmware or reprogram custom logic sequences. We work with your machine documentation to ensure exact functionality match.
What is the typical cost and lead time for Cincinnati Dynacomp repair?+
Lead time depends on fault severity. Simple faults — capacitor replacement, connector cleaning, bias network recalibration — are typically resolved in 3-5 days at competitive rates. Complex faults requiring custom component sourcing or EPROM reprogramming may take 7-10 days. Synchronics provides upfront quotations and repair estimates before any work begins. Call our technical team for a free diagnosis.
Do you offer preventive maintenance for Cincinnati Dynacomp equipment?+
Yes. Synchronics recommends annual preventive maintenance for Cincinnati Dynacomp systems — cleaning and tinning solder joints, replacing aging electrolytic capacitors, testing servo loop stability, and recalibrating proportional valve drivers. Preventive service extends machine uptime, prevents catastrophic failure, and is particularly important in humid Indian manufacturing environments where corrosion accelerates component degradation.
How do I send my CINCINNATI DYNACOMP 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 CINCINNATI DYNACOMP 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 CINCINNATI DYNACOMP 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 CINCINNATI DYNACOMP 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.
