Wiring
• Digital Inputs – Pushbuttons - 3 Wire Start/Stop
– Term. 18 (P 302) set to “Latched Start”
– Term. 16 (P 300) set to “Stop Inverse” for terminal 17, 27, 29,
32 or 33.
The diagram above shows the wiring for a 3-wire Start/Stop. Power comes from terminal 12,
a source of +24Vdc. Terminal 18 is programmed for Latched Start and terminal 16 is
programmed for Stop Inverse. When the NC PB stop switch is closed, s24Vdc to
terminal 16, then terminal 18 can be pressed s24Vdc into terminal 18 giving it a
start command. A latched signal continues to run the drive until the NC PB is opened,
sending a stop command to the drive.
