Connection example for three-phase motor
▶
For simple commissioning with the preset default settings, connect the
variable frequency drive as shown in the connection example above.
The potentiometer should have a fixed resistance (connection to control
signal terminals 5 and 7) of at least 1 k
Ω
, up to a maximum of 10 k
Ω
.
A standard fixed resistance of 4.7 k
Ω
is recommended.
Make sure that the enable contacts (FWD/REV) are open and the STO is
connected correctly before switching on the mains voltage.
When the specified supply voltage is applied at the mains connection
terminals (L1/L, L2/N, L3), the switched-mode power supply unit (SMPS) in
the DC link will be used to generate the control voltage and light up the
7-segment LED display (STOP).
At this point, the variable frequency drive will be ready for operation (correct
operating status) and in Stop mode.

If the connections for the setpoint value potentiometer cannot
be clearly allocated with terminals 5, 6 and 7, you should set the
potentiometer to about 50 % before giving the start
enable
(FWD/REV) for the first time.
