The Profibus-DP operation card module UD 73 is manufactured by Control Techniques for the Unidrive system. The Control Techniques UD 73 is a Profibus-DP interface card. A large option module for the Unidrive, the UD 73 is an add-on card. Network activity is dedicated to an 80C32 processor and System Protocol Chip using a Dual-Port RAM interface to communicate data transfer with the UD 73.
The Control Techniques UD 73 has two Profibus DP 9-way, D-type connectors. These are denoted as A and B on the large option module. To more easily connect into a multi-drop bus, the connectors are sockets (female end). The sockets are connected in parallel by way of the circuit board.
The 9-way female connectors have D-type pins for the following: Data (3), /Data, (8), OV Data (5), Remote power (+5V) for line termination (6), screen (shell).
The metal D-type shell is connected to the screen of the cable using screw locks. The locks are fitted to keep proper contact between the shells.
As there is no termination resistor supplied on the UD 73 module, external provisions should be supplied on the last node of the network. In the space where the network termination resistor is installed, the drive node must remain powered up when the network is interfacing with the other nodes. In case this is not happening, +5V and 0V may be run from another node that will always be powered up and +5V and 0V have to be run inside the screen of the Profibus-DP network cable.
Each line repeater adds one unit load to the line, so each line repeater is considered as replacing a network node. Each twisted pair must have a terminating resistor installed. This applies even if the twisted pair section runs between two line repeaters.
The maximum number of repeaters permissible between two line repeaters is three. The max number of nodes in a 4 section network is 122.
The max number of nodes permissible for connection to a single network without the use of a repeater is 32 nodes. The max line length at 1.5Mbits per second is 200m.
Normal downloaded DPL application programs retain full functionality on the UD 73. Program modifications are not necessary to use exiting DPL programs to run.
For installation of the UD 73 large option module by Control Techniques, the Unidrive must be disconnected from the high voltage power supply. The same holds for the removal of a large option module, it must be disconnected from the high voltage power supply. The high voltage power supply must remain disconnected for 5 minutes for the DC Bus capacitors to discharge. The Large Option module will click firmly into place when it is properly inserted.
The Control Techniques UD 73 may be removed by pulling the black tab. As the tab is pulled, the module disengages from the connector and may be taken out of the Drive.
The Control Techniques UD 73 large option module comes with a two-year warranty.
