2.1.4 Optional: disabling the STO
The two STO inputs (STO1 and STO2, see section 2.1.2) have to be supplied with the specified DC
voltage in order to enable the VLC’s driver power stage to operate the actuator. If the external means
of supplying the DC voltage is not considered, the VLC’s on-board +5V supply can be used to supply
STO1 and STO2, and together with connecting the STO_COM with the GND, the power stage is enabled.
This is shown in Figure 2.3. When both STO1 and STO2 are energized, the STO_FB output becomes
active to indicate the drive is ready to be operated.
