Page 4: Foreword
Safe Torque Off (STO) safety function (described as standard in DIN EN 61800-5-2) to Pilz drive controllers of the PMC SC6 or PMC SI6 series. STO prevents an electrical rotating magnetic field, needed for the operation of synchronous or asynchronous motors, from being generated in a drive controller. Additional safety functions can be built upon the STO function with the suitable external wiring, such as Safe Stop 1 (SS1-t). -
