Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13191229 (model ERBD082R600W) is a dynamic braking resistor belonging to the ERBD Series, engineered to absorb and dissipate regenerative electrical energy generated during controlled motor deceleration. Designed with a nominal resistance of 82 Ohms and a continuous power absorption rating of 600 Watts, this unit operates within intermediate DC bus circuits up to 800V DC. By converting kinetic energy back-fed from decelerating motor loads into thermal energy, it prevents intermediate DC link overvoltage trips during rapid stopping cycles. This device is routinely deployed in demanding automation environments such as material handling conveyors, automotive assembly systems, packaging lines, and hoists.
Connecting the ERBD082R600W to an inverter is accomplished directly via the dedicated brake chopper power terminals RB1 and RB2. As a passive electromechanical component, installing a replacement unit does not require software configuration, parameter adjustments, or drive commissioning routines. Thermal protection is integrated directly into the assembly using a potential-free normally closed (NC) thermal switch contact, which should be wired into the main control circuit or drive controller digital input to trigger automated power isolation in the event of thermal overload. When replacing an existing unit, ABC Industrial Parts can assist maintenance teams with sourcing verified components to keep production lines running smoothly.
Diagnostic monitoring relies on the status of the integrated thermal switch, which opens its normally closed contact whenever internal operating temperatures exceed safety limits. A tripped contact alerts the supervisory controller to stop braking operations before hardware damage occurs. Initial field checks for a suspected fault include verifying solid mechanical and electrical connections at terminals RB1 and RB2, confirming continuity across the NC thermal switch terminals under cold conditions, and ensuring external wiring is intact. Resistor elements damaged by severe thermal overload cannot be repaired in the field, making quick replacement with a tested spare from ABC Industrial Parts the most efficient path to restoring normal machine operation.

Diagnostics and Status Indication
Thermal diagnostics on the Lenze 13191229 ERBD082R600W are executed via an integrated potential-free normally closed (NC) thermal switch contact. Under standard operating temperatures, the switch remains closed, maintaining loop continuity. If repetitive dynamic braking causes thermal thresholds to be exceeded, the contact opens automatically to signal an overtemperature state to the attached controller or safety feedback circuit.
By integrating this switch into the drive system digital input or hardware interlock circuit, automated shutdown routines can be triggered immediately upon overtemperature detection. This prevents sustained thermal stress on both the braking resistor and connected drive components during fault conditions.
Replacement and Spare Part Considerations
When replacing an existing Lenze 13191229 (ERBD082R600W) resistor, ensure that the power connection terminals RB1 and RB2 are cleanly wired and securely torqued. Because this unit functions as a direct electromechanical dynamic braking module, no software parameters, firmware matching, or parameter downloads are necessary prior to putting the replacement into service.
Verify that the thermal safety contact is integrated into the control logic to retain overtemperature protection. The unit is designed for seamless operation across Lenze 8400 inverters, Lenze 9300 servo inverters, and Lenze i500 cabinet frequency inverters, provided the total resistance of 82 Ohms and 600W continuous power capacity match system dynamic braking requirements.
Frequently Asked Questions
How does the Lenze 13191229 braking resistor protect variable frequency drives?
The ERBD082R600W absorbs regenerative energy produced during dynamic motor deceleration and converts it into heat. This prevents excessive voltage accumulation in the drive intermediate DC bus, protecting drive components from tripping on overvoltage errors up to 800V DC.
Does installing a replacement ERBD082R600W require drive reprogramming?
No. The Lenze 13191229 is a passive electromechanical accessory that connects directly to the drive brake chopper terminals RB1 and RB2. It requires no parameter settings, firmware updates, or software configuration to operate.
How does the integrated thermal switch function on this braking resistor?
The unit includes a potential-free normally closed (NC) thermal contact. If excessive heat builds up in the resistor element, the contact opens, signaling an overtemperature fault to the controller or control loop to isolate power.
Which Lenze inverter series are compatible with the ERBD082R600W resistor?
The 13191229 braking resistor is compatible with Lenze 8400 inverters, Lenze 9300 servo inverters, and Lenze i500 cabinet frequency inverters.
