Safe Torque Off (STO) is the quickest and safest way to remove power from a motor. And the WEG CFW500 drive has both standard STO and SS1-t where you can control the decel ramp. Part 1 uses a simple ESTOP button wired directly to the drive's STO module. Part 2 uses a safety relay to built a fully compliant safety system. Learn all about it in this brief hands-on tutorial. This drive can produce full rated torque down to zero RPM and is available in NEMA4x/IP66 enclosures for OUTDOOR use in direct sunlight! It's available in up to 60 hp and has all the high end features you would expect like Dynamic Braking, PID, built-in PLC, Safe Torque Off (STO/SSI), two remote keypad options, Modbus TCP, EtherNet/IP, 65kVA SCCR, FOC or Torque Mode, Sensorless Vector, etc.
