Motor Information
The Basic Setup and Overload programming group allows the user to set
parameters indicating to the controller which motor is connected. It is important
to correctly input the data to achieve the best performance from your controller.
Motor Data Entry
In the Program mode, enter the correct values into the Overload group:
ATTENTION: For overload protection, it is critical that the data be entered as it
appears on the motor nameplate.
Description Option Display
Overload Class
(1) (2)
The factor default setting disables overload
protection. To enable it, enter the desired trip class
in this parameter.
(1) Found in Overload programming group. Only one location needs to be programmed.
(2) Found in Basic Set Up programming group.
Disable, 10, 15, 20, 30
Service Factor
(1) (2)
Enter the value from the motor’s nameplate.
0.01 to 1.99
Motor FLC
(1) (2) (3)
Enter the value from the motor’s nameplate.
(3) Refer to the SMC Flex controller nameplate for maximum ratings. Exceeding these could result in damage to the controller.
1.0 to 2200A
Overload Reset
(1) (2)
Allows the user to select either a manual or auto
reset after an overload.
Manual, Auto
Motor Connection
(2) (4)
Enter the type of motor being connected to the SMC

Line, Delta
Line Voltage
(2) (3)
Enter the system voltage in this parameter. This
must be done to ensure optimum motor
performance and correct operation of undervoltage
and overvoltage protection.
