This option provides the STO (Safe Torque Off) function via an emergency push-button mounted on the door of the control com-
partment. The control terminals of the control card are extended from inside the drive module and routed out to the terminal block
set -XD2 in the control compartment. The emergency push-button is wired between terminals -XD2.10 and -XD2.19.
Activating the emergency push-button prevents the unit from generating the voltage required to rotate the motor. The option pro-
vides:
Safe Torque Off (STO), as defined by EN IEC 61800-5-2.
Stop Category 0, as defined in EN 60204-1.
