Current Limit

Level

Limits the current supplied to the motor throughout the Torque Ramp Start cycle.

Stop Mode Programs the desired Stop Mode.

(3)

Coast, Soft Stop, Linear Speed, Pump Stop Coast

Stop Time Programs the amount of time desired to ramp from full to zero voltage for Soft, Linear, and

Pump Stop mode. Actual ramp stop time depends on the stop mode selected and load

inertia.

Overload Class Required for motor protection. Lets you select the time-to-trip for the built-in Motor

Overload. This selection is based on the type of motor being used and the application.

5…30 10

Service Factor Required for motor protection. This programmed value is taken directly from the nameplate

and used by the controller to determine the ultimate Overload Trip Current.

0.01…1.99 1.15

Motor FLC Required for motor protection. This programmed value is taken directly from the motor

nameplate.

(1) In the AUTO Detect [default] selection, the controller automatically checks the motor configuration.

(2) Enter a value to limit the current but not low enough to inhibit the start cycle.

(3) The stop mode does not need to match the start mode (example: a Soft Start can have a stop mode programmed for Coast, or Linear Stop—there is no Current Limit Stop or Torque Stop mode).

(4) Relay Operational Options (for example, ON and OFF delay, etc.) are provided in the File: Setup, Group: I/O selection sequence. See Ta ble 1 1

(5) For best results with a Pump Start, it is recommended that the tuning cycle be run. The SMC-50 control module automatically performs the tuning cycle the first time the motor is run. You can also

force this manually by setting the Force Tuning parameter to TRUE (=1), which is accessed from the File Setup, Group Adv. Tuning or by pressing and holding the SMC-50 control module’s Reset button

for 10 seconds with the motor stopped.

(6) You can program a start delay time to delay starting for a period after the initiation of the START command. You can access the Start Delay parameter from the Group Starting selection. See Tab le 11

(7) Any auxiliary output configured for Aux Control using the AuxX Config parameter is under control of its associated bit from the Aux Control, Parameter 180. See Parameter 180 information for bit

assignments. NOTE: This function enables forcing an output, ON or OFF.

ATTENTION: For Overload Protection, it is critical that you enter the data into

the SMC-50 control module as it appears on the motor nameplate.
