28
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, sending +24Vdc to
terminal 16, then terminal 18 can be pressed sending +24Vdc 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.
