Power
Fig. 6
The Integrated Controller and Operator Panel must be
connected to a 24 Vdc power supply unit.
The same 24 Vdc power supply can feed several
devices.
Make sure that the current issued by the power supply
is higher than the total maximum current absorbed by all
the devices connected.
230 VAC
Considering that the device has no switch, it is necessary
to install one before it, with a protective fuse.
The switch has to be positioned in the immediate vicinity of
the device and be easy for the operator to reach (Fig. 6).
Fig. 7
For the 24 Vdc power supply, use a separate line
from that used for electromechanical power devices
such as relays, contactors, solenoids, etc. If there
are considerable changes in the mains voltage, use a
voltage stabiliser.
Near to high frequency generators or arc welders, use
adequate grid filters. Connect the power cables to the
power connector.
Fit the ferrite core, supplied with the product, as close
as possible to the device to limit the susceptibility of the
device to electromagnetic disturbance (Fig. 7).
The 24 Vdc power cables must follow a separate route
from the power cables of the system or the machine.
Make sure that the earth connection is efficient. A
non-existent or inefficient earth connection can make
the operation of the device unstable, due to excessive
environmental.
In particular, check that:
•
the voltage between ground and earth is < 1 V;
•
the ohm resistance is < 6 Ω.
CAN
The CAN port is optional.
Connect the cable for the CAN field bus (CANopen
protocol). The maximum length of the cable depends
on the transmission speed. (See the manual for further
information).
Considering that the CAN port is opto-isolated, it is not
necessary to disconnect the power to the device before
connecting it.
Warning: The CAN port has a line termination.
If the CPU module is the last or the first device on
the CAN line, you have to insert the termination (120 Ω
resistance, ¼ W, 5%) by setting jumper J1 as shown in
figure 8.
Remember that the CAN bus must be terminated at both
ends.
Notes
The CAN line termination is settable with jumper J1 as
shown figure 9.
RS485
The RS485 port is optional.
Considering that the RS485 is opto-isolated, it is not
optional
necessary to disconnect the power to the Integrated
Controller and Control Panel and to the device to be
connected before connecting them.
For GEFRAN Keypad
The maximum length of the cable depends on the
optional
transmission speed. (See the manual for further
optional
information).
optional
The RS485 port is equipped with internal
termination and polarization, as shown in the
figure 10
Configuration of RS485
polarization and termination
The RS485 line polarizations and termination are settable
Configuration of CAN termination
with jumper J2 as shown figure 11.
Ethernet
SD card not supplied. Available
as accessory
The Ethernet port lets you connect the Contro Panel to
a computer or a corporate LAN or, if the product has the
option, to an Ethercat network. The connection cable to
use (either straight or crossover) depends on the type of
device that has to be connected.
For the connection, use a CAT6 UTP cable or superior,
You can also use a CAT5e cable (only for ETHERCAT).
The maximum length of the Ethernet cable is 100 metres.
+
Do not run the Ethernet cable alongside the machine
-
24 VDC
power cables, to avoid interference with data transmission.
USB
The USB port is optional and is used to connect external
devices compliant to the USB standard.
The connector is Type A and the port supports version
USB 2.0, with speed up to 480 Mbit/s.
The port is able to issue a current of 500 mA at 5 Vdc to
power USB devices.
The maximum length allowed for the USB cable is 5
metres. It is possible to directly access the USB port of
the controller from the panel using the transfer cable
(accessory to order separately). To fit the socket of this
cable, the panel thickness, in the position chosen, should
not exceed 2 mm.
SD Card
The SD Card mass memory lets you store data and applications.
SD Card function is defined by position of the rotary selector (use positions 0 to 9 only; unless otherwise
instructed, do not use positions A to F).
RS232
The RS232 port is optional. Considering that the RS232 port is not insulated, it is necessary to disconnect
the power to the Control Panel and to the device to be connected before connecting them.
The connection cable must be screened and not exceed a length of 3 metres.
Entry into service
1.1 A max
For the entry in service of the device (configuration and loading the application program) Please refer to the
installation manual and use GF_Project Vx, freely downloadable from the site www.gefran.it.
