Siemens6SN1123-1AA00-0AA0SIMODRIVE 611 Axis Power Module, Internal Cooling, Supplied with 6SN1118-0AA11-0AA0 Closed-Loop Control Card

Product Description

What this part is

Siemens SIMODRIVE 611 power module — the axis inverter stage of a 611 drive stack. It takes DC from the common DC link and inverts it to three-phase PWM output to drive one or more servo axes. Line rectification and DC-link charging are handled by a separate line-supply / infeed module in the 6SN114x range.

Supplied with a 6SN1118-0AA11-0AA0 closed-loop control plug-in card fitted in the module’s front slot. The power module carries the power stage; the plug-in card carries the regulation, setpoint interface and encoder inputs.

Decoding the order code

6SN1: SIMODRIVE 611 system prefix.

123: power module, the axis inverter. 6SN114x covers the infeed / line-supply modules and 6SN111x the plug-in control cards.

-1AA00: module form and cooling variant, internal heat dissipation.

-0AA0: the rating field, the smallest step in the 6SN1123-1AA00 internal-cooling ladder, which runs upward through -0BA (25 A), -0CA (50 A), -0DA (80 A) and -0EA (160 A). The trailing digit is the hardware generation within a rating.

Rating and cooling

Internal heat dissipation releases the module’s heat into the cabinet. Back-panel cut-outs differ between the internal-cooling and external-cooling module forms.

Siemens quotes the 6SN1123 range in rated output amps. Rated motor current at a given module rating differs by motor family: 1FT5, 1FT6 and asynchronous main-spindle motors each draw a different rated current.

Set composition

One power module with one 6SN1118-0AA11-0AA0 closed-loop control card fitted. SIMODRIVE 611 stacks are assembled module by module on a common rail.
