▶ Connect the variable frequency drive according to the connection
example above for the simple commissioning with the specified default
settings (see connecting example above).
The potentiometer should have a fixed resistance (connection to control
signal terminals 5 and 7) of at least 1 kΩ and up to a maximum of 10 kΩ.
A standard fixed resistance of 4.7 kΩ is recommended.
Make sure that the enable contacts (FWD/REV) are open before switching on
the mains voltage.
￫
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 release
(FWD/REV) for the first time.
When the specified supply voltage is applied at the mains connection termi-
nals (L1/L, L2/N, L3), the switched-mode power supply unit (SMPS) in the
internal 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.
The start enable signal is sent by activating one of the digital inputs with
+24 V:
• Terminal 1: FWD = Clockwise rotating field (Forward Run)
• Terminal 2: REV = Counterclockwise rotating field (Reverse Run)
The FWD and REV control commands are interlocked (exclusive OR) and
require a rising voltage edge.
