The user must configure the following output channels as PWM outputs and use the
“OBIOMotionPWM” function block.
● “PWM”: Output channel 4
● “PWM”: Output channel 5
● “PWM”: Output channel 6
● “PWM”: Output channel 7
If the user configures the output 4...7 as PWM using the “OBIOMotionPWM” function block, up
to four Software PTO can be realized offering then only the Pulse/Direction mode.
The Pulse output will always use the fast output channels O4…O7 and the direction output of
the function block can be assigned to any other output e.g. O0…O3 or also outputs from a S500
I/O module.
