STO cordset for Lexium 32i drives
The Schneider VW3M94CR03 is a 3-meter STO (Safe Torque Off) cordset for the Lexium 32i servo drive family. It carries the IEC 61800-5-2 functional safety standard rating, which means it's designed for the safety-related control circuit that removes drive torque without disconnecting mains power — the kind of signal path you'd run from a safety relay or motion controller to the drive's STO input. The cable uses 4 x 0.34 mm² conductors with M8 male-to-female connectors on each end — a standard pinout for this drive generation. The 3-meter length suits cabinet-to-motor distances in a typical machine cell; if your layout needs a different reach, the VW3M94CR03 is the fixed-length factory assembly, not a field-terminated cable.
The IEC 61800-5-2 standard is the key spec here — it covers the functional safety requirements for adjustable-speed drive systems. This cordset is the physical link in the STO chain: the M8 connectors carry the 24 VDC safety signal from the drive's STO terminal block to the motor's brake or feedback connector. The 4 x 0.34 mm² cross-section handles the signal current without excessive voltage drop over 3 meters, and the M8 form factor matches the drive's dedicated STO port — no adapter needed.
