Digital inputs

ENABLE (X3A/1)
Functions:
}
A "1" signal enables the inverted rectifier of the servo amplifier in order to drive the mo-
tor.
}
The enable is only possible if the inputs STO1-ENABLE and STO2-ENABLE are con-
nected for the safety function in accordance with the application (see section: "Digital
inputs STO1-ENABLE (X4/7), STO2-ENABLE (X4/5)".
}
In a disabled condition ("0" signal), the connected motor is torque-free.
} PLC-compatible (IEC 61131-2 Type 1), volt-free, reference earth is DGND
Further information and connection examples can be found in this chapter under "Safety
