Siemens6SN1123-1AA00-0DA0SIMODRIVE 611 Axis Power Module, 80 A Rating Step, Internal Cooling, PWM Interface Build

Product Description

What this part is:

Siemens 6SN1123-1AA00-0DA0 is a SIMODRIVE 611 power module, the axis inverter section of a 611 drive stack, supplied as one module. It takes DC from the drive group’s common DC link and inverts it to three-phase PWM output for a servo motor. This unit is the direct PWM interface build: the power stage is commanded by pulse-width-modulation signals from an external controller, which closes the current loop. Condition: used, takeout, tested.

Decoding the designation:

6SN1 — Siemens SIMODRIVE 611 system prefix.

123 — power module, the axis inverter. 6SN114x covers the infeed modules and 6SN111x the plug-in closed-loop control cards.

-1AA00 — module form with internal heat dissipation.

-0DA0 — rating field. In the 6SN1123-1AA00 internal-cooling ladder the -0DA step is the 80 A rating, above -0BA (25 A) and -0CA (50 A) and below -0EA (160 A). The trailing digit is the hardware generation within the rating.

Specifications:

Brand: Siemens.

Part Number: 6SN1123-1AA00-0DA0.

Series: SIMODRIVE 611.

Type: Power module, axis inverter.

Output Amperage: 80 A rating step.

Cooling: Internal heat dissipation.

Communication Standard: Direct PWM power-stage interface.

Controller Platform: SIMODRIVE 611, SINUMERIK machine tool drive platform.

Mounting Type: Cabinet rail mount, module-to-module with shared DC-link busbars.

Country of Origin: Germany.

Manufacturer Status: Discontinued by Siemens; successor platform SINAMICS S120.

Dimensions and mounting:

Mounting Type: Cabinet rail mount, module-to-module with shared DC-link busbars. Internal cooling releases the module’s losses into the cabinet air. The back-panel cut-out and airflow path differ between the internal-cooling and external-cooling module forms.

Compatibility and replacement:

6SN1123-1AA00-0DA1: the same 80 A internal-cooling frame at a later hardware generation. 6SN1123-1AA00-0BA0/-0BA2 (25 A), -0CA0/-0CA1 (50 A) and -0EA1 (160 A): the same family at other ratings. 6SN1123-1AA00-0AA0: the smallest step in the same ladder. Also listed as 6SN11231AA000DA0, 6SN1123 1AA00 0DA0 and 6SN1123-1AA000DA0.

Frequently asked questions:

What does this module do in a SIMODRIVE 611 stack?

It is the axis inverter: it takes DC from the common DC link and inverts it to three-phase PWM output for a servo motor. Line rectification and DC-link charging come from a separate 6SN114x infeed module.

What is the output rating and cooling?

Output Amperage: 80 A rating step. Cooling: Internal heat dissipation.

What command interface does it use?

Communication Standard: Direct PWM power-stage interface. The external controller closes the current loop.
