Parameter setting:
 Select whether you wish to use it as an input or output in the PDrive
commissioning software (“Digital I/O” window).
][Funktion_Ein_dig_STO_ENABLE_Ueber_protego_D_48_72
Safety function STO, digital inputs STO1-ENABLE (X4/7), STO2-EN-
ABLE (X4/5)
][Funktion_Ein_dig_STO_ENABLE_protego_D
The two digital inputs STO1-ENABLE (1st shutdown route) and STO2-
ENABLE (2nd shutdown route) are used to shut down the inverted rec-
tifier safely.
Functions when operated without a safety card:
 The digital inputs STO1-ENABLE and STO2-ENABLE enable the in-
verted rectifier on the servo amplifier.
 Single or dual-channel activation of the safety function STO is possi-
ble.
 The servo amplifier is ready for operation when there is a 24 V signal
at the inputs.
 If the STO1-ENABLE and/or STO2-ENABLE input is open, no more
power is transferred to the motor. The drive becomes torque-free and
runs down.
 In conjunction with the output from a safety relay or safety control
system, you can safely prevent the drive from restarting.
 Requirements of the outputs on a safety control system or safety re-
lay:
– Single-channel activation of STO without feedback: PL d (Cat. 2) of
EN ISO 13849-1, SIL CL 2 of EN/IEC 62061
– Dual-channel activation of STO with feedback: PL e (Cat. 4) of
EN ISO 13849-1, SIL CL 3 of EN/IEC 62061
 If the safety function STO is not needed, STO1-ENABLE and STO2-
ENABLE must be connected directly to 24 V.
 This input is not compatible with IEC 61131-2.
 Volt-free, reference earth is XGND
INFORMATION
The inputs are active high or low, depending on the selected
function.
