The basic parameter set-up for Soft Start selection with SMB Smart
Motor Braking option follows:

Starting Mode
Allows the user to program the SMC Dialog
Plus controller for the type of starting that best
fits the application.
Soft Start, Current Limit
Ramp Time
This sets the time period during which the
controller will ramp the output voltage. 0 to 30 seconds
Initial Torque
The initial reduced voltage output level for the
voltage ramp is established and adjusted with
this parameter.
0 to 90% of locked rotor torque
Kickstart Time
A boost of 550% of full load current is provided
to the motor for the programmed time period. 0.0 to 2.0 seconds
Stall Delay
Allows the user to program the stall protection
delay time. The delay time begins after the
start time has timed out.
0 to 10 seconds
Energy Saver
The Energy Saver feature monitors the motor
load, phasing back the voltage output to the
motor when the motor is lightly loaded or
unloaded for an extended period of time.
Off, On
Aux Contacts 1&2
Two form C contacts are provided as standard
with the SMC Dialog Plus controller. These
contacts are located at terminals 18, 19, and
20. Aux Contacts 1&2 allows the user to
configure the operation of the contacts.
Normal, Up-to-speed
Aux Contact 3
A third auxiliary contact is provided between
terminal 29 and 30. Aux Contact 3 allows the
user to program the operation of the contact.
Normal, Fault
Contact 3 Config
This parameter provides the user with the
ability to program the “powered up” state of
the third auxiliary contact.
N.O., N.C.
Braking Current
Allows the user to program the percentage of
braking current applied to the motor during the
stop sequence. With the SMB Smart Motor
Braking option, this is the current applied to
bring the motor to zero speed.
0 to 400% full load current
Parameter Mgmt
The newly programmed parameters values can
be saved to memory, or the factory default
parameter values can be recalled. Ready, Default Init., Recll Frm EE,
