Official lifecycle
Prod. Discont.
Siemens lists 611U HR 6SN1118-0NH01-0AA0 as partially compatible.
Decision rule: treat the successor as an engineered migration, not a drop-in replacement.
01 / Match
Use the complete 6SN1122-0BA11-0AA1 article number and record the installed power module.
02 / Preserve
Archive motor data, analog scaling, terminal assignments and start-up parameters.
03 / Recommission
Validate direction, speed response, protections and machine interlocks after any exchange.
02
Signal and commissioning map
Six installed interfaces define the analog drive.
The route follows the physical command, enable, relay, start-up and monitoring connections.

03 · Buyer FAQ
Buyer questions for Siemens 6SN1122-0BA11-0AA1
Practical answers for buyers, engineers and maintenance teams.
Q01
What is Siemens 6SN1122-0BA11-0AA1 used for?
Siemens 6SN1122-0BA11-0AA1 is a SIMODRIVE 611-A plug-in closed-loop control unit for induction motor drives. Siemens identifies the exact order number as the universal analog version.
Q02
Does Siemens 6SN1122-0BA11-0AA1 have one fixed motor-current rating?
No. The Siemens current-controller selection table ties the applicable current values to the installed 611 power module. The control unit and power module must therefore be checked as one configured drive.
Q03
Which connections distinguish Siemens 6SN1122-0BA11-0AA1 from other 6SN1122 versions?
Siemens states that X412 and X432 are available only on 6SN1122-0BA11-0AA1. X412 accepts KTY84 or PTC motor-temperature monitoring, while X432 provides the VERO connection for maximum-speed monitoring.
Q04
What must be verified before Siemens 6SN1122-0BA11-0AA1 is replaced?
Match the complete order number, 611 power module, motor data, analog setpoint scaling, enable and relay wiring, X412/X432 connections, commissioning software and saved parameter set.
Q05
Is Siemens 6SN1122-0BA11-0AA1 discontinued, and is there an official successor?
Yes. Siemens marks 6SN1122-0BA11-0AA1 as Prod. Discont. and lists 611U HR 6SN1118-0NH01-0AA0 as a partially compatible successor. It is not a drop-in replacement and requires a full interface and commissioning review.
Q06
What should be sent for a Siemens 6SN1122-0BA11-0AA1 manual and quotation request?
Send clear nameplate photos, the power-module order number, motor data, X412/X432 wiring, software or parameter-backup details, quantity, destination and required date so the correct documentation and supply option can be confirmed.
