Allows the user to select the operation of Input Terminal A1,
Option Input 1 on the 150-SM4 Digital I/O Option Module.
Disable
: Disable the input - ignores any assertion to Input 1,
Terminal A1.
Start: Initiates a start as set up by the start parameters at Input
1, Terminal A1 (High).
Coast
: Initiates a coast stop.- no current to motor at Input 1,
Terminal A1 (Low).
Stop Option: Initiates a stop maneuver as set up by the
stopping parameters at Input 1 (Low).
[Start/Coast]: if Input 1 = 0 - Stops motor; 1- Initiates a start
as set up by the start parameters
Start/Stop
: if Input 1 = 0- Initiates a stop maneuver as set up
by stopping parameters; 1- Initiates a start as set up by the start
parameters
Dual Ramp: if Input 1 = 0 - Use starting mode 1; 1 - Use
starting mode 2
OL Select: if Input 1 = 0 - Use Motor Overload Class 1; 1 - Use
Motor Overload Class 2
Fault
: A fault condition forced if Input 1= 1.
Fault NC: A fault condition forced if Input 1 = 0.
Clear Fault: Clear a fault from input 1 Terminal A1 (High).
Emerg Run
: Allow motor to run in emergency run mode if
asserted from Input 1, Terminal A1 - does not start motor
(High).
