Product Description

What this part is

Siemens 6SC6100-0AB00, the voltage clamping (voltage limitation) printed circuit board for SIMODRIVE 610 and 210 AC feed drive systems, covering the 0.9 to 90 kW range. Its job is DC-link overvoltage protection: when regenerated energy from a decelerating axis pushes the DC link voltage up faster than it can be returned to the mains, this board detects the rise and switches the surplus into a pulsed (braking) resistor so the link voltage stays inside safe limits. It is the control and switching board for that function — not a drive, not a power supply, and not an axis module. Siemens’ own board number is 462 010.9001.00.

Decoding the order code

6SC: Siemens SIMODRIVE converter and drive hardware. 6100: the SIMODRIVE 610 supply, control and auxiliary board range. 0AB00: the voltage clamping / voltage limitation PCB variant, 0.9/90 kW.

Siemens’ full catalogue description for this item reads: SIMODRIVE 610/210 AC feed drive P.C.B, voltage clamping 0.9/90 kW (without pulsed resistor and installation material).

Published specifications

System: SIMODRIVE 610 and SIMODRIVE 210 AC feed drives. Function: voltage clamping / voltage limitation PCB (DC link overvoltage limiting). Power range covered: 0.9 to 90 kW. Siemens category: drive controllers. Siemens board number: 462 010.9001.00. Supplied without pulsed resistor and without installation material. Approximate dimensions: 254 x 229 x 51 mm. Product status: phase-out. Made in Germany.

What is not included

Siemens sold this item as the board on its own, and the order description states it explicitly: without pulsed resistor and without installation material. The pulsed resistor is the physical braking resistor that absorbs the energy this board switches, and the installation material is the mounting hardware kit. Neither is in the box, and the board cannot perform its function without a resistor connected.

Also not included: the SIMODRIVE line supply infeed module; feed or axis power modules; control modules; the line filter or commutating reactor; DC link bus bars or bus connection kits; the equipment bus and drive bus cables; fuses; a rack, tier mounting or cabinet; or documentation.

What these specs mean in practice

Voltage clamping matters most on machines that decelerate hard or often. A SIMODRIVE infeed returns braking energy to the mains, and there is a limit to how fast it can do that. A mains dip, a lost phase, or an emergency stop that drops the supply contactor while axes are still moving all leave the energy nowhere to go. Without clamping, the DC link voltage climbs until something in the drive group fails, typically the electrolytic capacitors or an output stage. The pulsed resistor gives that energy somewhere to go and this board decides when to send it there.

The 0.9 to 90 kW span means one board covers a wide range of drive group sizes. The resistor is matched to the peak and average braking energy of the particular machine. An undersized resistor overheats and opens, at which point the clamping function is gone and the board still appears healthy.

This is a phase-out product. Surplus and repair are the supply routes.

Mounting data

Approximate dimensions: 254 x 229 x 51 mm. Installation material is not supplied. A clamping board sits directly across the DC link by design, and the DC link capacitors hold a lethal charge after the mains is removed. Braking resistors run hot in service and dissipate their heat where they are mounted. A failed resistor and a failed board present identically as an overvoltage trip.

Interchange guidance

6SC6100-0AB00 is also written 6SC61000AB00, 6SC6100 0AB00 and 6SC6-100-0AB00, and carries Siemens board number 462 010.9001.00. Other 6SC6100 suffixes are different boards, not equivalents. 6SC6100-0GE01 is the power supply / infeed module in the same range, an entirely different function. The 6SC611x feed modules (6SC6114-0AA00, 6SC6116-0AA00) are axis power stages and unrelated to this board. The later SIMODRIVE 611 range using 6SN11xx numbers is a different generation with its own pulsed-resistor arrangements.
