MSD Servo Drive Single-Axis System, MSD Servo Drive Multi-Axis System and 
MSDSingle-Axis Servo Drive Compact support the "STO" (Safe Torque Off) safety 
function in accordance with the requirements of ENISO13849-1 and IEC/EN61800-
5-2/ IEC/EN62061/ IEC/EN61508.

The digital input "ENPO" is reserved for the hardware enable. At the setting P100[0] 
- MPRO_INPUT_FS_ENPO = "OFF(0)" the digital input signal is used merely for safe 
shutdown of the drive and as protection against switching on.
With the setting P100[0] - MPRO_INPUT_FS_ENPO = “START (1)" in combination 
with P144[0] - MPRO_DRVCOM_AUTO_START = "ON" autostart mode is activated 
(only in MSD Servo Drive). With "STO active" activating the "ENPO" is sufficient to 
start control of the drive. When the "ENPO" is cancelled the drive runs down 
uncontrolled. If the switch-on delay is active, the power stage starts when the preset 
timer has elapsed.
