P2.2.1 143 IO Terminal 1 Start Stop Logic 1,2,3 RW
This parameter defines the start and stop of the drive with the digital signals.
0 = Para ID 190: DI closed contact = start forward Para ID 191: DI closed contact = start reverse - This
would be considered 2 wire control with either a contact used on the Start FWD or Start REV
commands. Contacts Open the motor stops.
