Parameter Information Appendix A
65 Stop Mode 0/5 0 [Coast]
Soft Stop
Linear Speed
Pump Stop
Reserved
External Brake
Allows the user to program the SMC-50 for the type of stopping
that best suits the application.
[Coast]
: Coast-to-Rest.
Soft stop
: Slowly reduces current by reducing voltage applied
to the motor over a programmed period of time.
Linear Speed: Stops the motor following a linear speed ramp
over a programmed period of time.
Pump Stop
: Slowly reduces current by reducing voltage
applied to the motor using the pump
stop algorithm over a programmed period of time.
External Brake: Closes an external contactor to apply braking
current to the motor.
R/W
66 Stop Time Sec 0/999 0 Sets the time period which the controller will ramp the voltage
during a stopping maneuver.
R/W
67 Backspin Timer Sec 0/999 0 Avoids starting into a backspin condition. The timer begins
counting after a stop is completed (coast, stop maneuver, fault
etc). All start inputs will be ignored until the backspin timer has
timed out.
R/W
68 Pump Pedestal % 0/50 0 Provides the ability to adjust the pump algorithm slightly for
different applications. Typically, this is used to shorten the ramp
time before the SMC-50 starts to get aggressive in its pump
stopping maneuver.
R/W
75 Overload Class 5/30 10 Sets the desired trip class of internal solid state overload.
Overload fault and alarms are enabled and disabled in the
Starter Fault En and Starter Alarm parameters.
R/W
76 Overload Class 2 5/30 10 Allows user to set the internal solid state overload to an
alternate trip class. This Trip Class is used when an input
(configured as overload select) is asserted.
R/W
77 Service Factor 0.01/1.99 1.15 Parameter to enter the value of the motor's service factor from
the nameplate.
R/W
78 Motor FLC Amps 1/2200 1.0 Parameter to enter the Full Load Current (FLC) value from the
motor's nameplate.
R/W
79 Motor FLC 2 Amps 1/2200 1.0 Second motor FLC setting to be used when Overload #2 is
selected using the "Overload 2" input.
R/W
80 OL Reset Level %MTU 1/99 75 When the level of Motor Thermal Usage (MTU) drops below this
limit after an OL fault, an overload reset can occur. If restart is
enabled, the motor overload will automatically reset when the
MTU drops below this level.
R/W
81 OL Shunt Time Secs 0/999 0 Disables the overload from incrementing MTU for the selected
time period after a start or stop command is initiated.
R/W
82 OL Inhibit Time Secs 0/999 0 Disables the overload from tripping during stopping
maneuvers. The MTU. Therm Usage continues to increment
during these maneuvers.
R/W
83 Overload A Level %MTU 0/100 90 The MTU level that will set off an alarm when exceeded. The
Overload bit the Motor Alarm En parameter must be set to
signal an alarm.
