ENABLE (X3A/1)
Functions:
 A “1” signal enables the inverted rectifier of the servo amplifier in or-
der to drive the motor.
 The enable is only possible if the inputs STO1-ENABLE and STO2-
ENABLE are connected 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 chap-
ter under "Safety function STO".
Parameter setting:
 A software enable is also required in the commissioning software (log-
ic AND connection).
