Edge-controlled HW enable
With an edge-controlled enable, output cams are output at the output only if the enable status
exists before the output cam start. The enable status is controlled by a configured Measuring
Input Technology Object.
For the edge-controlled enable, the technology object measuring input is only measured if
enabled. The enable status is controlled by a configured measuring input technology object
linked with the enable channel.
For the measuring input TO, only the "one-time measuring" mode is permitted with the following
edge detection:
● Rising edge
● Falling edge
● Both edges
Measuring of "Both edges, first rising" and "Both edges, first falling" and the "Cyclic measuring"
mode is not supported.
Via the measuring input TO
● the positions of the enable edges can be evaluated (see SIMOTION Motion Control - Output
Cams and Measuring Inputs" Function Manual). Please note that the measuring range is
monitored in the IPO, IPO2 or position control cycle clock, depending on the configured
measuring input cycle clock.
● Set or reset the enable status.
The enable status is set when the configured edge arrives.
The enable status is reset
– At the beginning of the measuring range configured at the Measuring Input TO (with
range setting: "Measure in specified range")
– using the program command _enableMeasuringInput (with range setting: "Measure
without a defined range")
The enable status can be monitored via the I/O area of the enable input.
If the enable status is retracted before the output cam ends, the output cam is still output until
the end if it has already started. New output cams are no longer output.
