Frequently Asked Questions (FAQ)

Q1: What is the Siemens 6AU1432-2AA00-0AA0?

It is the SIMOTION CX32-2 Controller Extension, a drive-based control module that increases the number of axes controllable by a SIMOTION D4x5-2 motion controller. It is a SINAMICS S120 Booksize-format module with 4 DRIVE-CLiQ interfaces and integrated digital I/O .

Q2: What is the primary function of the CX32-2?

Its primary function is to scale the drive axis count of a SIMOTION D4x5-2 system. When the main controller’s integrated drive control is insufficient for the required number of axes, adding a CX32-2 provides additional drive-side computing capacity .

Q3: How many axes can one CX32-2 control?

Each CX32-2 can manage up to 6 servo axes, 6 vector axes, or 12 U/f axes (including one infeed). It cannot mix servo and vector control on the same module, but U/f can be combined with either .

Q4: How many CX32-2 modules can be used with a SIMOTION controller?

• D425-2: up to 3 CX32-2 modules

• D435-2 / D445-2 / D455-2: up to 5 CX32-2 modules

Q5: Is this product still in production?
