5.16.1.1.14 Example program 3
This program writes the speed parameter from PLC to inverter, performs forward rotation by
input X1, and reverse rotation by input X2.
By re-writing D10 in the peripheral equipment or the display unit, the frequency of the inverter
can be changed.
This program also monitors the frequency and output current in the inverter.
