49 Starting Mode 0/5 2 -Full Voltage
-Current Limit
-[Soft Start]
-Linear
Speed-
(Sensorless)
-Torque Ramp
-Pump Start
Used to program the SMC controller for the type of starting
mode that best fits 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
50 Ramp Time Sec 0/1000 10.0 Enables the user the ability to configure the time period during
which the controller will ramp the output voltage.
R/W
51 Initial Torque %LRT 0/90 70 The initial reduced voltage output level for the voltage ramp is
established and adjusted with this parameter.
R/W
52 Max. Torque % 0/300 250 Gives the user ability to configure the maximum torque limit of
a torque ramp during a torque start operation.
R/W
53 Cur Limit Level %FLC 50/600 350 The current limit level that is applied for the ramp time
selected.
R/W
54 Kickstart Time SEC 0/2 0.0 A boost of current is applied to the motor for this programmed
time.
R/W
55 Kickstart Level %LRT 0/90 0 Gives the user the ability to adjust the amount of current boost
applied to the motor during the kickstart period.

Allows the user to select the operation of Terminal 11, Input 1
on the control module.
Disable
: Disable the input - ignores any assertion to Input 1,
Terminal 11.
Start: Initiates a start as set up by the start parameters at Input
1, Terminal 11 (High).
Coast
: Initiates a coast stop.- no current to motor at Input 1,
Terminal 11 (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 11 (High).
Emerg Run: Allow motor to run in emergency run mode if
asserted from Input 1, Terminal 11 - does not start motor
(High).
