Chapter 4 Programming
Full Voltage Start with Stop
The SMC-50 control module may be programmed to provide a full voltage start
(output voltage to the motor reaches full voltage within five line power cycles).
To provide a Full Voltage Start to the motor, the only start parameter that
requires adjustment is the Starting Mode. The Basic parameter set should be used
to program Full Voltage Start to ensure configuration of other motor
configuration and basic protection parameters. Use the parameters in Ta ble 17
to
program a Full Voltage Start and Simple or Stop Mode operation. You can access
the basic parameter set with the HIM (see Table 11 on page 96
).

(1) In the AUTO Detect [default] selection, the controller automatically checks the motor configuration.
(2) The stopping mode does not need to match the starting mode (for 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).
(3) 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
