Ctrl Signal 1 B (P3.5.1.3) = Start (Edge)
Ctrl Signal 2 B (P3.5.1.4) = Reverse
The selections including the text 'edge' shall be used to exclude the possibility of an unintentional start when,
for example, power is connected, re-connected after a power failure, after a fault reset, after the drive is
stopped by Run Enable (Run Enable = False) or when the control place is changed to I/O control.
