Cont.4
CAUTION!
At any time, there may be a loss of motor control and separate/independent application
measures should be taken to ensure that such loss of motor control cannot present a safety
hazard.
RISK ASSESSMENT
Under fault conditions, power loss or unintended operating conditions, the drive may not
operate as intended. In particular:
•Stored energy might not discharge to safe
levels as quickly as suggested, and can still
be present even though the drive appears to
be switched off
•The motor's direction of rotation might not
be controlled
•The motor speed might not be controlled
•The motor might be energised
A drive is a component within a drive system that may influence its operation or effects under
a fault condition. Consideration must be given to:
•Stored energy •Supply disconnects •Sequencing logic •Unintended
operation

8903/SP Peer-to-Peer Communications Interface
PEER-TO-PEER COMMUNICATIONS INTERFACE
Introduction
This manual describes the Parker SSD Drives’ Peer-to-Peer Communications Interface Option
(TechCard).
The 8903/SP Peer-to-Peer TechCard uses a proprietary protocol. It may be used in the
following ways:
•Connect DSE 890 to all drives in the system
•Peer-to-peer data exchange with other drives
Part Number
The part number for the Peer-to-Peer Communications Interface Option is :
8903/SP
8903/SP/FF (indicates a factory-fitted option)
Used On
The TechCard can be used on 890 drives with the following Product Codes:
890SD/.. 890SD Standalone Drive
890CD/.. 890CD Common Bus Drive
Refer to the 890 Engineering Reference Manual, Appendix E for Product Code details.
Restrictions
When the 8903/SP is fitted, the options 8903/CB and 8903/DN cannot be used.

Installation
WARNING!
Disconnect all sources of power before attempting installation.
Caution
This TechCard contains ESD (Electrostatic
Discharge) sensitive parts. Observe static
control precautions when handling,
installing and servicing this option.
To Remove the Control Board
1. Remove the blank covers, each secured by
a single screw (1) that fit over the
TechCard slots.
2. Undo the top and bottom captive screws
in the handles (2) of the Control Board.
3. Pull gently on the handles (2) and slide
the Control Board out of the drive.
Note:
Save the blank cover and screw for future
use. The drive should not be operated
without a TechCard or blank cover. When
fitted, these maintain the drive's IP20
rating.

Fitting the TechCard
The TechCard fits on to the Control Board.
1. Insert the connector into the TechCard as shown. The pins of the connector will protrude
through into the connector on the other side of the TechCard.
2. Press the assembly into the OPTION B connector (adjacent to terminals X13, X14 and
X15) on the Control Board. Ensure that the front panel of the TechCard overlaps the front
of the Control Board.

Re-fitting the Control Board
1. Slide the board into the drive, engaging the edges of the boards into the slots. Push until
the back edge of the Control Board PCB locates with the connectors in the drive.
2. Tighten in position using the top and bottom screws in the handles of the Control Board.
3. Screw the TechCard in position using the captive screw on the front of the option.

Wiring the System
Terminal X53
Cable Specification
The media for the Peer-to-Peer TechCard is a shielded copper cable consisting of one twisted
pair and two cores for power. The recommended bus cable is specified in ISO/DIS 11898.
The twisted pair of the cable must be connected to the terminals SIG_L and SIG_H. It is
recommended to connect one of the cores for power to the terminal GND (do not connect to
safety earth). The cable shield must be connected to the terminal SCREEN on the connector
X53 at each node. Nodes should be connected in a daisy chain configuration. The cable
shield should be connected to safety earth at one point only.
Keep electrically noisy and sensitive cables apart. Pay particular attention to screening and
earthing of motor cables. Where necessary, sensitive cables should cross noisy cables at 90°
to minimise capacitive coupling.
Terminators
Both nodes at the end of the trunk must have a terminating resistor. A
resistor of 124Ω(±1%, minimum ¼ watt) is recommended, but it
should be chosen to equal as closely as possible the characteristic
impedance of the cable. The terminating resistor must be connected
between the pins SIG_L and SIG_H.
All other nodes in the system should not have a terminating resistor.

Configuring Peer-to-Peer
Switch Setup
The option requires the setup of the physical address and
baud rate using the switches (1 – 8) on the front of the
TechCard.
Note that the state of the switches is continually monitored
so that the physical address and baud rate may be changed
at any time. A change in the switch state will cause the
module to go back to the initialisation state. It is
recommended to set up the switches before power-up to
avoid bus disturbances.
Physical Address Selection
The physical address of a node must be selected using the switches (1-6) on the front of the
TechCard. Each address must be unique.
One node must have address zero, which then becomes the master node. It is recommended
that consecutive addresses are used from address zero upwards.

Baud Rate Selection
Each Peer-to-Peer TechCard connected to the bus must be set to the same baud rate. This is
done using the switches (7-8) on the front of the TechCard.
The baud rate selection depends on the cable length of the bus.
1000kbits/s 800kbits/s
500kbits/s 250kbits/s

The two status LEDs MS (Module Status) and BS (Bus Status) display the current state of the
Peer-to-Peer option.

DSE Module List
If excessive peer-to-peer data is being transmitted across the bus then the Errs (errors) column
in the Module List in DSE will show non-zero values. The Module Status (MS) LED will also
flicker red.
To resolve this problem reduce the amount / rate of peer-to-peer data until Errs is zero.
Increasing the baud rate, if possible, will also help.
