Siemens 6SN1122-0BA11-0AA1 Induction Motor Closed-Loop Control Unit

The Siemens 6SN1122-0BA11-0AA1 is a SIMODRIVE 611-A plug-in closed-loop control unit for induction-motor drives in the universal analog version.

Article & System Context

Product Profile

Siemens' SIMODRIVE 611 analog documentation lists 6SN1122-0BA11-0AA1 as the analog induction-motor control variant used with the larger 611 power-module classes.

The module provides the control electronics for compatible induction-motor drive configurations and must be combined with the appropriate power section and machine commissioning data.

System Matching

Compatibility

Match 6SN1122-0BA11-0AA1 to the installed SIMODRIVE 611 power module and induction motor. Do not select a replacement solely by connector appearance; verify power-section current, motor data, analog control wiring and commissioning settings.
Typical Use

Applications

Industrial Induction Motors
Closed-loop control of compatible induction-motor drives.
CNC Auxiliary Drives
Legacy machine-tool applications using SIMODRIVE 611-A induction-motor control.
Spindle / Process Drives
Applications where the induction-motor control is integrated into a modular 611 drive lineup.
Legacy Maintenance
Exact-replacement service for installed SIMODRIVE 611-A systems.
Customer Questions

Frequently Asked Questions

1. What motor type is 6SN1122-0BA11-0AA1 intended for?
