 Example
In the above example, if the general-input contact Xw is 1, the motor runs at 10 Hz in the forward direc-
tion. If the general-input contact Xw is 2, the motor runs at 15 Hz in the reverse direction. With other val-
ues, the motor stops.

Block number Operation
1 After the "select” command, the program branches to the following “case” commands depending
on the value of Xw.
Branches to the “case 1” if Xw1, to the “case 2” if Xw2, and to the “case else” if Xw = a value
other than 1 and 2.
2 to 4 Executes if Xw  1. Sets the frequency reference variable to 10.00 Hz, operates the inverter in the
forward direction, and executes the next steps after the “endselect” command.
5 to 7 Executes if Xw  2. Sets the frequency reference variable to 15.00 Hz, operates the inverter in
reverse direction, and executes the next steps after “endselect” command.
8 to 10 Executes if Xw  a value other than 1 and 2. Stops the inverter and executes the next steps after
the “endselect” command.
11 Jumps to the block 1: Top unconditionally.
