The VW3L2M211R30 is a pre-assembled cable kit for Altivar drives fitted with printed circuit board connectors — the kind you find on motion-sequence drives where you need both I/O and safe torque off in one harness. It runs 3 m (9.8 ft) from the drive-side PCB connector to an open cable end at the machine side, with an insert that packs 2 I/O channels and 1 safe torque off (STO) circuit through an M8 connector.
The 3 m length (9.8 ft) is the working span between drive and the field device — enough for a cabinet-to-machine reach on a compact cell, but not a long cable-run. The STO channel via M8 connector is the safety-rated path that cuts drive torque without removing power; if your safety circuit expects a 24 VDC STO input on an M8 pinout, this cable delivers it pre-wired. The open cable end means you terminate the field side yourself — gland plate, terminal block, or direct to the motor-side junction box.
