Operation<br />
Commissioning with Control Signal Terminals<br />
(Factory Setting)<br />
M-Max frequency inverters are set in the factory and can be<br />
started directly via the control signal terminals by connecting<br />
the motor outputs allocated for the input voltage (see<br />
connection example below).<br />
You can skip this section if you want to set up the<br />
parameters directly for optimal operation of the frequency<br />
inverter based on the motor data (rating plate) and the<br />
application.<br />
The following shows a simplified connecting example of a<br />
connection with default settings.<br />

Connect the frequency inverter according to the connection<br />
example for simple commissioning with the specified default<br />
settings (see connecting example above).<br />
If the connections for the setpoint value potentiometer<br />
cannot be clearly allocated with terminals 1, 2 and 3, you<br />
should set the potentiometer to about 50% before giving the<br />
start release (FWD/REV) for the first time.<br />
When the specified power supply is applied to connection<br />
terminal L2/N and L3 (MMX11) or L1 and L2/N (MMX12) or<br />
L1, L2/N and L3 (MMX32, MMX34, MMX35), the LCD<br />
display lights up and all segments are displayed briefly.<br />
The frequency inverter runs a self-test automatically when<br />
the power is applied.<br />

The arrows ( ) in the top status line of the LCD display<br />
show the operating status:<br />
● READY = proper operating status<br />
● STOP = stop (no start command)<br />
The arrows ( ) in the bottom status line show the controller<br />
commands. Actuation is done via the control signal terminals<br />
(I/O = Control Input/Output) in the factory setting.<br />
The FWD mark (forward) designates the basic rotational<br />
direction (phase sequence for a clockwise rotating field) on<br />
connection terminals U/T1, V/T2 and W/T3.<br />
The operating data of the output frequency is shown in the<br />
LCD display in alternating sequence with M1.1 and 0.00 Hz.<br />
The arrow in the left-hand status line indicates menu level<br />
MON (Monitor = operating data display).
