Chapter 4 Programming
Linear Acceleration (Linear Speed) Start with Stop
Use the parameters in Table 1 4 to program a Linear Acceleration Start and
Simple Stop Mode operation. You can access the Basic parameter set with the
HIM (see Ta ble 11
).
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.

Line Voltage Select the value of line voltage being used in the system. The correct line voltage
value must be entered for the voltage protection functions to work properly.

Ramp Time Programs the time period that the controller will ramp the output voltage up to full
voltage and to full speed from Stop. With the Linear Speed Starting mode, the time to
ramp to full speed closes to this value depending on load characteristics.
0…1000 s 10 seconds
Initial Torque The initial reduced output (torque) level for the voltage ramp to the motor is
established and adjusted to this parameter. Torque level at which the ramp begins.
0…90% LRT 70% LRT
Current Limit
Level
Limits the current supplied to the motor throughout the Linear Start and Stop
cycle.

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 stopping 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.
