Redundancy mode (pulse)
If both channel 2 and channel 3 are configured as pulse outputs, channel 3 can be
configured for redundancy mode to follow channel 2 shifted by 90˚or 180˚ of the functional
width of the pulse. If set to redundancy mode, channel 3 inherits all channel 2 settings. The
functional width of the pulse is two times the pulse "On" duration. The flow direction will
determine whether channel 3 is shifted before or after channel 2.
The following examples describe the pulse functionalities for channel 2 and 3 in redundancy
mode:
Channel 2 configured as positive and negative direction and channel 3 set to redundancy
mode 90°
