Heidenhain UP 110 Braking Resistor Module Id.Nr. 341516-01

Buy online your Heidenhain UP 110 Braking Resistor Module Id.Nr. 341516-01 from our UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

The HEIDENHAIN UP 110 (Id.Nr. 341516-01) is a braking resistor module designed to absorb regenerative energy generated by servo motors and spindle drives during deceleration and emergency stops. By dissipating this energy as heat, it protects the DC bus against overvoltage and ensures reliable braking performance on machines equipped with HEIDENHAIN drive systems.

Installed inside the electrical cabinet, the UP 110 is intended for HEIDENHAIN drives that require an external braking resistor. During rapid deceleration or high-inertia movements, it dissipates the regenerated energy returned to the DC link, stabilizing the bus voltage and preventing overvoltage faults that could interrupt production.

This module is widely used on CNC machining centers, lathes, and grinding machines equipped with HEIDENHAIN drive technology, where frequent braking cycles are part of normal operation. When replacing the unit, it is important to verify the Id.Nr. 341516-01 to ensure full compatibility with the original drive system and electrical specifications.

The UP 110 provides a peak power rating of 60 kW for up to 2 seconds, a switch-on voltage of 740 V, and a module width of 50 mm. Manufactured in Germany, it is designed for installation in industrial control cabinets with adequate cooling and thermal clearance to ensure reliable performance during repeated braking cycles.

In maintenance applications, this braking resistor is commonly replaced when it becomes open circuit, drifts out of specification, or causes repeated DC bus overvoltage alarms during machine deceleration. Keeping a replacement unit in stock helps minimize downtime and allows machines to return to production quickly.

Each module can be inspected and tested on dedicated test benches to verify its thermal performance and energy dissipation capabilities before shipment. Protective industrial packaging safeguards the terminals and housing during transport.

The HEIDENHAIN UP 110 is a dependable replacement solution for maintaining and extending the service life of HEIDENHAIN drive systems while improving the reliability and availability of CNC machine tools.

Frequently asked questions about UP110:

How can I confirm this module fits my HEIDENHAIN drive package?
Match the code and Id.Nr. 341516-01 with your drive documentation. Verify the required resistance and power rating specified by the drive and compare connector layout and mounting footprint with your original unit.

Can this be used as a drop-in replacement for the same code from an older installation?
Yes, when the module code and Id.Nr match the original. Always confirm cabinet space, wiring length and terminal style before the swap to keep the changeout straightforward.

What are typical signs that the braking resistor needs replacement?
Frequent DC bus overvoltage trips during deceleration, visible discoloration or heat marks on the resistor housing, and abnormal resistance readings during offline checks indicate it should be replaced.

Do you support refurbished units and repair options?
Depending on condition and sourcing, refurbished units, repair service or an exchange service may be available. Contact our team with your drive details and the Id.Nr for the best turnaround plan.
