The brief instructions (see the figure on Page 53) provide a<br />
graphical description of the few steps necessary up to the<br />
motor start.<br />
● The frequency inverter carries out a self-test when the<br />
supply voltage is applied. The backlight of the LCD display<br />
is switched on and all segments are briefly actuated<br />
When the MMX is switched on for the first time, it activates<br />
the Quickstart Wizard to guide you step-by-step through the<br />
drive parameters (alternating display of P1.1 = 1).<br />
First read “Parameters” starting on Page 58.<br />
You can access the parameters when P1.1 = 0. Pressing<br />
[BACK/RESET] [ ] [OK] leads you to the operating data<br />
display MON. This is always displayed after the power supply<br />
is switched off.<br />
