Safety circuit for servodrive-Lenze-AC Tech Corp

A new safety circuits on the ES and RS models of PositionServo drives disables output to the motor so the drive cannot generate torque in the motor. Called “Safe Standstill,” in the event of a single-fault (single-component) failure, the ISO 13849-1 safety circuit will still function and disable the drive.
