4.1.3 Motor Wiring
The motor must be connected to the drive terminal block X1:
X1 - 4 U Phase U
X1 - 5 V Phase V
X1 - 6 W Phase W
Depending on the motor there are different connections: RS/FHA-Serie is equipped with a cable exit (flying
leads; not suitable for trailing applications), BSM50, 63 and 80 and FFA-series have a power connector.
A wiring example is shown in chapter 4.3.
The sequence of the motor leads is not arbitrary.
Therefore the motor leads must be wired in the
right sequence to avoid uncontrolled motor
function.
Motor Cables
All cables have to be screened. The maximum cable length is 25m.
4.1.4 24VDC - Connection (optional)
A 24V stand-by option is available for all drives. With this option the control circuits are supplied by an
external voltage. The advantage of the option is that, if the main power is switched off control circuits are still
supplied and position information does not get lost.
Wiring 24VDC-option:
X1-9
X1-10
With the 24V option the DC-Bus voltage can be
variable from 0V to maximum Vcc.
NOTE: The velocity controller can be optimized only for
a certain DC-Bus voltage. Therefore the controller
behaviour will change or different DC-Bus voltages.
The current control will be not affected.
Attention: Please take care of correct connection of
24 VDC and GND!
Miswiring will lead to malfunction.
