Lexium 32Schneider Electric LXM32MD72N4 Lexium 32 LXM32M 24A 7kW Three-Phase Servo Drive
Lexium 32 LXM32M servo drive, three-phase, 24 A / 7 kW, integrated STO, card-based fieldbus.
Description
About the LXM32M
About the LXM32M
The Schneider Electric LXM32MD72N4 is the top-current Lexium 32 LXM32M motion servo drive, rated for three-phase supply at 200-240 V or 380-480 V with a continuous output current of 24 A at 8 kHz and a nominal power of 7 kW at 400 V. It carries integrated STO safety and accepts a fieldbus communication card for single-axis motion control on the highest-load machines in the range.

- EN/IEC 61800-3
Selection Notes
At 24 A continuous / 7 kW, the LXM32MD72N4 is the largest frame in the LXM32M line and steps up from the 6 A / 1.8 kW MD18N4 for axes whose motor draws well above 1.8 kW continuous. This frame drops to 2 capture discrete inputs with STO as the only integrated safety function - no separate eSM safety card for SS1, SS2, SLS, or SOS is listed for this variant, unlike the lower-current MD18N4 and MD30M2 frames - so a machine needing category-1 stop or safe limited speed on this axis should confirm that requirement before specifying it. The wider 108 mm housing reflects the higher continuous and peak current the power stage carries.
Applications
High-load single-axis motion on the largest machines in a Lexium 32 line - main spindle or high-torque conveyor drives where the axis motor draws several kilowatts continuously.
