HARMUTH ELEKTRONIK Product Lines We Repair
Our engineers are trained on the full HARMUTH ELEKTRONIK product range. Below are the major product families we service.
HSM Servo Amplifiers
Compact servo drives for stepper and DC servo motors in precision positioning applications. Common faults include firmware corruption, power stage failures under inductive loads, and I/O module communication loss in high-vibration textile and packaging machinery.
HMC Motion Controllers
Standalone multi-axis motion controllers with integrated PWM and stepper outputs. Frequent repair issues include SD card read failures, encoder signal loss, over-temperature shutdown, and relay contact wear in high-cycle industrial applications.
HPA Stepper Driver Modules
Modular stepper motor drivers with microstepping and current limiting for conveyor systems and assembly machinery. Repairs commonly address burned driver ICs, shorted output stages, and loss of step/direction signal integrity in noisy factory floors.
HIM Industrial Amplifiers
DC and AC amplifier modules for proportional valve control and analog signal conditioning in hydraulic and pneumatic systems. Typical failures include capacitor degradation, offset drift in sensor input stages, and output short-circuit protection lock.
HEC Encoder Interface Modules
Industrial encoder interface cards supporting incremental and absolute encoders with CANopen and PROFIBUS connectivity. Common issues include quadrature signal misinterpretation, connector corrosion in damp environments, and firmware version incompatibility.

Common HARMUTH ELEKTRONIK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HARMUTH ELEKTRONIK equipment arriving at our workshop.
- ✓HSM servo amplifier power stage burnout — Harmuth HSM series use high-current MOSFET output stages susceptible to inductive voltage spikes when driving stepper coils without adequate freewheeling diodes. Indian textile machinery often runs older unfiltered motor wiring, exacerbating this fault.
- ✓HMC controller SD card file corruption — Harmuth HMC motion controllers store axis profiles and homing routines on SD cards. Repeated power cycling during changeover operations, combined with improper mounting (vibration exposure), causes file system errors and profile read failures.
- ✓Encoder signal loss and commutation errors — Harmuth servo amplifiers rely on clean quadrature encoder signals for closed-loop control. In Indian automotive supply plants with high EMI from welding equipment and VFDs, shielded cables deteriorate, causing phase jitter and false zero-crossing detection.
- ✓HPA stepper driver IC failure and no-output condition — Harmuth HPA-6A and HPA-12A modules use integrated stepper driver chips (A3967 or similar) that fail catastrophically if motor coils experience reverse polarity connection or phase-to-phase shorts during maintenance in Indian plants.
- ✓HIM amplifier offset drift and signal instability — Harmuth HIM industrial amplifiers contain analog front-end circuits with precision resistor dividers. Thermal cycling in uncontrolled factory environments and electrolytic capacitor ageing cause input offset voltage to drift, producing erratic analog output to proportional solenoids.
- ✓HEC encoder interface firmware version mismatch — Harmuth HEC modules shipped before 2015 use older firmware incompatible with modern encoder protocols (e.g., SSI on CANopen gateways). Upgrading machinery in Indian plants sometimes results in mixed hardware generations causing handshake failures.

Frequently Asked Questions — HARMUTH ELEKTRONIK Repairs
Do you repair Harmuth Elektronik equipment anywhere in India?+
Yes, Synchronics repairs the complete Harmuth Elektronik range across all of India. We offer PAN-India door pickup service from major cities including Mumbai, Delhi, Bangalore, Hyderabad, Pune, Chennai, Ahmedabad, Kolkata, and all other regions. All repairs are performed at our main ISO-certified facility in Vadodara, Gujarat, with turnaround typically 5-10 working days including firmware updates and full function testing.
What Harmuth Elektronik servo amplifier models do you stock parts for?+
Synchronics maintains a service stock of Harmuth HSM-2.5 through HSM-40 servo amplifier modules, including replacement power stage assemblies, gate drive boards, and firmware SD cards. We also keep encoder interface modules (HEC-INC, HEC-ABS, HEC-CANopen) and stepper driver ICs in common ratings. If an exotic component is needed, we source through authorized Harmuth distributors with 2-3 week lead times, but most Indian plants run standard models we stock.
Can you upgrade old Harmuth HMC motion controllers with new firmware?+
Yes. Synchronics can securely upgrade HMC-100 through HMC-400 controllers to the latest Harmuth firmware releases. We back up all user motion profiles and parameter settings before any upgrade, test the new firmware under simulated load conditions, and restore your application data post-upgrade. This is especially useful for Indian plants integrating legacy Harmuth controllers with modern CANopen networks.
Why does my Harmuth stepper driver emit a burning smell and lose power?+
This is typically catastrophic failure of the stepper output stage (MOSFET or driver IC) caused by phase-to-phase motor coil shorts or reverse polarity during wiring work. Harmuth HPA modules offer no built-in anti-reverse protection, so miswired motors instantly blow the output stage. Synchronics diagnoses via thermal imaging and continuity testing, identifies the root cause in your motor connections, and rebuilds the driver with component replacement and reinforced protection.
Does Synchronics provide documentation and calibration certificates for Harmuth repairs?+
Yes. Every Harmuth repair completed at Synchronics includes a detailed repair report documenting the fault, components replaced, and calibration data (for HIM amplifiers and HEC encoders). We provide printable calibration certificates that comply with ISO 9001 and Indian automotive quality standards, essential for QMS compliance in automotive and pharmaceutical supply chains.
How do I send my HARMUTH ELEKTRONIK 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 HARMUTH ELEKTRONIK 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 HARMUTH ELEKTRONIK 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 HARMUTH ELEKTRONIK 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.
