The adjustable frequency drive can be operated in 3 ways:
1. Graphical Local Control Panel (GLCP), see 5.1.2
2. Numeric Local Control Panel (NLCP), see 5.1.3
3. RS-485 serial communication or USB, both for PC connection, see 5.1.4
If the adjustable frequency drive is fitted with a serial communication bus option, please refer to relevant documentation.
5.1.2 How to operate the numeric LCP (NLCP)
The following instructions are valid for the NLCP (LCP 101).
The control panel is divided into four functional groups:
1. Numeric display.
2. Menu key and LEDs - changing parameters and switching be-
tween display functions.
