STO Muting
Muting means de-activating the STO function. A convenient method for muting the STO function is provided
for those applications not using the STO function.
An internal power source in the drive is brought out to the Safety connector J4. Connecting the STO inputs
between this bypass power source and its ground supplies power to the STO opto-couplers allowing the
PWM outputs to be controlled by the drive. Figure 10 below shows the muting connector circuit, table 13 lists
the jumper connections, and fig. 9 shows the jumper locations.
