Result

You have inserted the instruction "MC_Power" to enable the axis in the program and

assigned it to the technological object "Axis".

The enabling of the axis depends on the value of the "ON" tag at the "Enable" input:

● When the bit of the "ON" tag has the value "0" (machine off), the axis is disabled.

● When the bit of the "ON" tag has the value "1" (machine on), the axis is enabled.

In the next section you will program the motion of the conveyor relative to the starting point.
