Allows the user to select the operation of Terminal 11, Input 2
on the control module.
[Disable]
: Disable the input - ignores any assertion to Input 2,
Terminal 11.
Start
: Initiates a start as set up by the start parameters at Input
2, Terminal 11 (High).
Coast: Initiates a coast stop.- no current to motor at Input 2,
Terminal 11 (Low).
Stop Option
: Initiates a stop maneuver as set up by the
stopping parameters at Input 2 (Low).
Start/Coast: if Input 2 = 0 - Stops motor; 1- Initiates a start as
set up by the start parameters
Start/Stop: if Input 2 = 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 2 = 0 - Use starting mode 1; 1 - Use
starting mode 2
OL Select: if Input 2 = 0 - Use Motor Overload Class 1; 1 - Use
Motor Overload Class 2
Fault: A fault condition forced if Input 2= 1.
Fault NC
: A fault condition forced if Input 2 = 0.
Clear Fault: Clear a fault from Input 2 Terminal 11 (High).
Emerg Run: Allow motor to run in emergency run mode if
asserted from Input 2, Terminal 11 - does not start motor
(High).

[Soft Start]
Linear Speed
Torque Ramp
Pump Start
Allows the user to program an alternate starting mode for the
SMC-50 that suits the application.
Full Voltage
: Apply full voltage to the motor at start.
Current Limit: Apply limited current for a programmed period
of time.
Soft start: Slowly increase current to load over a programmed
period of time.
Linear Speed
: Increase current to cause a linear acceleration of
the motor.
Torque Ramp: Slowly increase torque generated by motor over
fixed period of time.
Pump Start: Special starting algorithm for pump applications.
R/W
59 Ramp Time 2 Sec 0/1000 10.0 Allows the user to set an alternate time period during which the
controller will ramp the output voltage.
R/W
60 Initial Torque 2 %LRT 0/90 70 Allows the user to set an alternate initial reduced voltage
output level for the voltage ramp.
R/W
61 Max. Torque 2 % 0/300 250 Allows the user to set a alternate maximum torque limit of a
torque ramp during a torque start operation.
R/W
62 Cur Limit Level 2 %FLC 50/600 350 Allows the user to set an alternate current limit level that is
applied for the ramp time selected.
R/W
63 Kickstart Time 2 SEC 0/2 0 Allows the user to set an alternate boost current to be applied
to the motor for the programmed time.
R/W
64 Kickstart Level 2 %LRT 0/90 0 Allows the user to set an alternate adjustment of the amount of
current applied to the motor during the kickstart period.
