Brief Instructions
The brief instructions (see the figure on
Page 55
) provide a
graphical description of the few steps necessary up to the
motor start.
●
The frequency inverter carries out a self-test when the
supply voltage is applied. The backlight of the LCD display
is switched on and all segments are briefly actuated
When the MMX is switched on for the first time, it activates
the Quickstart Wizard to guide you step-by-step through the
drive parameters (alternating display of P1.1 = 1).
First read “Parameters” starting on
Page 60
.
You can access the parameters when P1.1 = 0. Pressing
[BACK/RESET] [
] [OK] leads you to the operating data
display MON. This is always displayed after the power supply
is switched off.
The frequency inverter is ready to start when there is an
alternating display M1.1
0.00 Hz.
●
The frequency inverter is now ready for operation, and is
factory set for activation and frequency setting via the
control signal terminals (I/0). The STOP button is active in
this mode
Changes are only possible when there is flashing at the entry
digit (press OK button).
●
The direction can be changed via the two arrow buttons
(< or >, cursor)
