￭ PC connection
There is a USB connector on the front of the control panel that can be used to connect a
PC to the drive. When a PC is connected to the control panel, the control panel keypad is
disabled.
￭ Fieldbus control
You can control the unit through a fieldbus interface if the unit is equipped with an optional
fieldbus adapter and when you have configured the control program for the fieldbus control

To be able to switch the main circuit breaker [Q1] and the supply unit on and off (Run enable
signal) through the fieldbus, the Run enable command at digital input DI2 must be on (1).
