System solution
The PowerDRIVE-System consists of three basic compo-
nents: up to 5 compact, fully automated positioning drives
PowerDRIVE, the intelligent decentral communication unit
PowerDRIVE-Box and the hybrid cables PowerDRIVE-
Connect suitable for use in drag chains.

The intelligent PowerDRIVE-Box simplifies commissioning
and allows an efficient integration of the PowerDRIVES in-
to the control of complex production plants. Various field
bus modules are available for the communication with the
central control system.
The PowerDRIVE-Box takes care of the entire power man-
agement for the positioning drives and significantly re-
duces the connection work. The supply of motor power,
supply of logic power and the internal CAN bus communi-
cation between the positioning drives and the Power-
DRIVE-Box are undertaken via the hybrid cable Power-
DRIVE-Connect. Instead of the usual two separate cables
for field bus communication and a third cable to supply
power to the positioning drives, the connection is reduced
to
ONE
hybrid cable suitable for use in drag chains; the lo-
gistics effort for the always identical PowerDRIVEs is mini-
mised. In the maximum configuration with 5 positioning
drives connected, the number of cables can typically be re-
ducedfrom15to5.
The automatic configuration of the PowerDRIVEs after
connection to the PowerDRIVE-BOX and the check on the
system parameters make commissioning straightforward
and quick, even without the central control system connec-
ted.
Construction of the PowerDRIVE-Box
GEL 6505A The compact housing of the PowerDRIVE-
Box made of cast aluminium is suitable for
mounting on top hat rails. For testing and
commissioning of each positioning drive,
there are state LEDs and push-buttons on the
front panel.
GEL 6505B The closed housing of stainless steel met
through the cable glands and blanking plugs
the protection class IP 69K. All indication and
connection elements are located inside.
For each positioning drive 3 state LEDs indicate the state
of the power supply and the communication. In case of a
malfunction or during an inspection, the drive voltage and
communication can be switched on or off using push-but-
tons under the LEDs. It is also possible to acknowledge er-
rors and perform a manual reset with the aid of the push-
buttons.
Via a USB interface, the device can be connected to a PC.
Using a terminal program, important parameters can be
read and set. Also, the firmware of the box can be updated
with the aid of a connected PC.
The pluggable fieldbus interface is supplied pre-assembled
as per the type code.
The hybrid cables for the positioning drives are connected
directly to the easily accessible and coded strips using
spring-cage terminals. The hybrid cables are earthed via
an earth rail.
For safe operation, the box provides integrated electronic
fuses. The PowerDRIVE-Box is earthed via an earth cable
and the additional earthing via the top-hat rail or mounting
brackets.
Power is supplied to the PowerDRIVE-Box and positioning
drives either via a common connection or via two separate
connections. Using separate supply, the power of the
drives can be switched off, for example during an “emer-
gency stop”, without interrupting the bus communication. In
this way state monitoring is ensured.
Integrated power management
The maximum power consumption can be programmed via
power management.
It is recommended to use a 24 V DC / 40 A voltage-stabi-
lised power supply that is preferably to be mounted beside
the PowerDRIVE-Box. The supply of power to the motors
and logic for the positioning drives is separate. For require-
ments in accordance with the new Machinery Directive, the
power for the motors can be switched via certified safety
relays in the plant. Nevertheless, continuous state monitor-
ing can be ensured, as the communication via the field bus
is not affected. In this way the drive can be safely shut
down.
PowerDRIVE-Connect
The hybrid cable PowerDRIVE-Connect is designed for
flexible application in drag chains and reaches a permissi-
ble dynamic bending radius of ten times the cable diameter
inatemperaturerangeof-40°Cto+80°C.Thediameter
of the cable is 9.5 mm. The hybrid cable is screened under
the PUR outer sheath. The internal communication cores
are fully insulated and multiply screened.
The positioning drive is available with hybrid cable and
connector. PowerDRIVE and PowerDRIVE-Box can be
quickly and easily connected with pre-assembled field at-
tachable hybrid connection cables .
The M23 quick-acting coupling of the plug connection per-
mits a rapid connection and disconnection of the devices.
In this manner, the positioning drive can be safely isolated
from the power supply within seconds for maintenance and
service work.
