(1) Since a set of switches do not provide the resolution to enter all possible Motor FLC combinations like a keypad, Switch S5 allows you to configure the
Motor’s FLC in the SMC50 by using a percent (%) of the controllers raed (e.g 90A, 110A, 140A, 180A, etc) FLC.
-
Example: For a 60A motor and a 90A controller, the % of Controller’s max FLC for 60A would be 64% of 90A (57.6A) or switch position 6.
(2) To determine the S5 switch setting for an inside the delta motor configuration use the following 2 equations:

1) If the calculated value doesn’t match a switch position use the previous (lower percent) switch setting
2) The inside the delta motor configuration can be selected using Parameter 44 (Motor Connection) or automatically during a controller Tuning process.
The following defines the functions of the 3 banks of On/Off 8-switch DIP switches. Each of the 3 banks is defined by
a high level functional name (e.g. Device, I/O and Protection) with each switch having a unique function.
