The SIMOTION CX32‑2 Controller Extension is a module in SINAMICS S120 booksize format. It enables the extension of the drive-side computing performance of the SIMOTION D4x5‑2 Control Units.

The integrated drive computing performance enables the SIMOTION D4x5‑2 Control Units to operate up to 6 servo, 6 vector or 12 V/f axes.

The SIMOTION CX32‑2 Controller Extension extends the drive computing performance by up to 6 additional servo, 6 vector or 12 V/f axes. This allows the number of axes of a multi-axis system to be increased according to the requirements of the application.

If required, several CX32‑2 Controller Extensions can be operated on one SIMOTION D4x5‑2 Control Unit.
