operation selection
Setting Pr. 882 = "1 to 3" enables the regeneration avoidance function.
Setting the parameter to "3" enables the regeneration avoidance function during normal operation, and disables the
function during deceleration-to-a-stop operation initiated by turn-OFF of the start signal. In this way, the machine can be
stopped quickly by using the regenerative braking equipment.

3.12 Operation command source and speed command source (Pr. 338, Pr. 339)

In the Network operation mode, commands from the external terminals and network are as listed below.
