In this control mode, youcan set parameters PNU C071 to C078 for bus operation using akeypad (OPE) or a PC. To save these changes, press the ENTER keyon the keypad or use the Save <strong>com</strong>mand of the DrivesSoftsoftware.X To set up the interface for <strong>com</strong>munications through Modbus,switch off the power supply.X Set the microswitch OPE/485 to position 485.With this setting, Modbus <strong>com</strong>munications begin when the DF51frequency inverter’s power supply is switched on (POWER LED islit).
