Drive Unit – VFD Wiring

[1] DC 24V supply (external or MLU../MLG.. option)
[2] CW/stop
[3] CCW/stop
[4] Setpoint switch mode f1/f2

[5] Ready signal (contact closed = ready for operation)
[6] BW braking resistor (only on units without mechanical
brake)

Functions of the CW/stop and CCW/stop terminals with binary control:

Direction of rotation CW active

Direction of rotation CCW active

Functions of the f1/f2 terminals:

Setpoint f1 active

Setpoint f2 active

Functions of the CW/stop and CCW/stop terminals with control via RS-485 interface/fieldbus:

Both directions of rotation
are enabled

Only CW direction of rotation
is enabled, setpoint
specifications for CCW
operation result in standstill
of drive

Only CCW direction of
rotation is enabled, setpoint
specifications for CW
operation result in standstill
of drive

Drive is blocked or brought to
a stop
