The processor modules could also provide up to 4 PTO (PWM) software output channels. To use that mode, the parameter of output channel of onboard I/O must be configured before it can be used. User should take these steps to configure this special PTO output function. The PTO outputs channels can be only used as Pulse / Direction mode. Please refer to the technical data ⮫ “Technical data of the PTO outputs” ⮫ “Technical data of the PWM outputs”.
The PTO channel is using a digital fast output configured as PWM output to generate the Pulse output and a standard digital output to indicate the direction. A dedicated PTO motion block will then control the channel to realize the functionality.
Up to 4 PTO can be then provided each using 2 digital outputs.
A mixed configuration of one HW PTO channel (e.g. Output 04 ... 05) and Pulse/Direction or Cc/Ccw mode together with up to 2 other software PTO Channels (e.g. O6, O7 + dedicated output) and only Pulse/Direction mode is then possible. Please refer to the technical data ⮫ Further information.
To achieve such a software PTO mode the following channel configuration must be done.
