POLAR-MOHR Equipment We Repair — By Category
POLAR-MOHR Product Lines We Repair
Our engineers are trained on the full POLAR-MOHR product range. Below are the major product families we service.
Polar-Mohr Guillotine Cutters (AutoCut, CutMaster)
High-precision programmable guillotine systems for sheet cutting in print finishing. Common issues include encoder feedback loss, servo drive faults, pneumatic pressure regulation failures, and PLC communication timeouts affecting cut accuracy and speed.
Polar-Mohr Automatic Paper Folders
Precision folder systems for multi-format folding in commercial printing. Failures often stem from stepper motor drive faults, timing belt wear, fold plate alignment sensor drift, and EEPROM corruption in control modules.
Polar-Mohr Drive Electronics & Motion Control
Brushless servo drives, stepper motor controllers, and AC inverters powering guillotine blades and folder mechanisms. Typical faults include IGBTs, capacitor failures, encoder communication loss, and overcurrent trips.
Polar-Mohr HMI & PLC Control Systems
Industrial touchpanels and programmable logic controllers managing machine operation, safety interlocks, and data logging. Common defects include LCD backlight failure, membrane keypad wear, PLC memory loss, and network interface card failures.
Polar-Mohr Hydraulic & Pneumatic Motor Units
DC and AC motors driving hydraulic pumps and pneumatic regulators in cutting and clamping mechanisms. Repair needs include bearing wear, brush carbon replacement, seal leakage, and pressure relief valve adjustment.

Common POLAR-MOHR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in POLAR-MOHR equipment arriving at our workshop.
- ✓Guillotine blade servo positioning error code E102 — Rotary encoder cable disconnection or hall sensor failure in Polar-Mohr's servo feedback circuit. Contamination from paper dust on sensor contacts is common in Indian print facilities with high ambient humidity.
- ✓Folder jam detection sensor malfunction — Infrared or photoelectric proximity sensor lens fouling or amplifier card failure in Polar-Mohr fold plate assembly. Dust accumulation on sensor windows prevents paper sheet detection, triggering false jam stops.
- ✓IGBT module burnout in drive power stage — Transient overvoltage spikes during guillotine blade acceleration, or internal gate driver circuit failure in Polar-Mohr servo drives. Inadequate cooling fan operation exacerbates thermal stress in humid Indian climates.
- ✓HMI touchscreen display unresponsiveness or garbled text — LCD backlight inverter board failure, damaged touch panel controller IC, or corrupted firmware in Polar-Mohr's control module. Power surges or brownouts in Indian industrial areas frequently damage these components.
- ✓Stepper motor stalling with position feedback loss — Microstepping driver chip failure, stepper coil open circuit, or loose step/direction signal connectors in Polar-Mohr folder mechanisms. Vibration loosens ribbon cables in older equipment.
- ✓PLC memory corruption or battery backup failure — Lithium coin cell battery depletion in Polar-Mohr PLC modules, or firmware flash wear-out after excessive program rewrites. Water ingress from cooling system leaks corrupts memory banks.

Frequently Asked Questions — POLAR-MOHR Repairs
Does Synchronics repair Polar-Mohr guillotine cutters and folder machines anywhere in India?+
Yes. Synchronics repairs the full Polar-Mohr product range across India — including AutoCut and CutMaster guillotines, Stahl and Polar-Mohr folder systems, servo drives, stepper motors, PLCs, and HMI panels. We offer door pickup and delivery from all major Indian cities: Mumbai, Delhi, Pune, Bangalore, Hyderabad, Ahmedabad, Kolkata, and Chennai. All repairs are performed at our ISO-certified facility in Vadodara, Gujarat.
What is the typical turnaround time for Polar-Mohr guillotine drive repair?+
Synchronics typically completes diagnosis within 48 hours. Most servo drive and stepper motor repairs take 5-7 working days, including component replacement, testing, and calibration. For urgent jobs, we offer express turnaround service. Complex PLC or HMI repairs may take 10-14 days depending on parts availability and firmware re-programming needs.
Can you repair Polar-Mohr equipment with encoder feedback errors or hall sensor faults?+
Absolutely. Encoder cable failures, hall sensor drift, and feedback amplifier faults are among the most common Polar-Mohr repairs we handle. Synchronics tests rotary encoders and magnetic sensors on dedicated test benches, replaces defective units, and recalibrates servo zero positions to restore cutting accuracy. We also apply protective conformal coating to sensor boards to prevent future dust contamination in print facilities.
Do you provide OEM spare parts or equivalent components for Polar-Mohr machines?+
Synchronics stocks critical Polar-Mohr spare parts including servo motor coupling units, stepper drivers, IGBT modules, and encoder cables. For obsolete components, we source equivalent replacements from authorised industrial electronics distributors. All parts are tested for compatibility before installation. We also offer component sourcing support if you have specific part numbers.
How does humidity in Indian print facilities affect Polar-Mohr equipment reliability?+
High humidity in coastal and monsoon regions causes moisture ingress, corrosion of circuit board traces, and sensor calibration drift in Polar-Mohr electronics. This leads to intermittent encoder faults, HMI panel malfunctions, and stepper motor stalling. Synchronics applies conformal coating and silica-based desiccant protection during repairs. We also recommend installing dehumidifiers or air drying units in machine enclosures for preventive maintenance in moisture-prone facilities.
How do I send my POLAR-MOHR 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 POLAR-MOHR 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 POLAR-MOHR 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 POLAR-MOHR 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.
