6SC6100-0AB00 SIMODRIVE DC-link voltage limiter board

Documented simodrive dc-link voltage limiter board function and system position for 6SC6100-0AB00

Documented drive function

Rebuilt from individual evidence

Siemens documentation shows 6SC6100-0AB00 as a DC-link voltage limiter used with SIMODRIVE drive equipment.

The board intervenes across the drive DC-link protection path so excess regenerative energy can be managed before it disturbs the connected drive group.

Exact reference: 6SC6100-0AB00
Category: Drives / VFD
Evidence checked: 2026-09-12

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Limits regenerated-energy overvoltage in the SIMODRIVE drive DC link.
System position: Sits between the incoming power supply and the motor in a variable-speed drive system.
Upstream / inputs: Receives the configured speed command and electrical power from the upstream drive circuit.
Downstream / outputs: Outputs controlled motor power and drive status to downstream machine control.
Limitations: Unknown: the installed project, wiring, firmware, operating duty, and current unit condition.
