6 IF2 I/O Interface to PDM

Publication 4100-IN001A-EN-P- February 2001

Overview

The IF2 I/O Interface to PDM is a printed circuit board intended for

use with the positioning drive modules (PDM).

Figure 1 Front View of I/O Interface Board

These drives are built with output stages which source current to

their loads, and input stages which require a current sinking input to

operate. The 24 volt supply from the drive to the input/output (I/O)

is floating, and if the negative side is connected to safety ground

there is a possibility that an earth fault on a control wire would

cause the I/O to go to an active state resulting in an unexpected

action from the drive. In order to comply with EN60204-1: 1993, it is

necessary to connect the 24 volt positive circuit to ground if any

external control conductors (i.e outside the control enclosure) are

connected to the I/O. This can create compatibility problems with

some programmable logic controllers, and the purpose of this board

is to reverse the polarity of the I/O circuit to remove the problem of

compatibility.

Publication 4100-IN001A-EN-P- February 2001

Installation

The interface is a DIN rail mounting unit which has a terminal strip

(1.5 mm

screw clamp type) down each side.

Mounting

The Interface board has 2 mounting feet on the back to attach it to

the DIN rail.

Wiring

The flying leads from the PDM drive is wired to the IF2 I/O Interface

to PDM board using the connector marked P1. The flying leads from

the external controller are wired to the connector marked P2 User.

Each set of connectors have 26 slots available and the wiring is a 1

to 1 set up. The IF2 I/O Interface should be mounted as close as

possible to the associated PDM. The wires from the PDM to the IF2

should be in the same railway and should not contain any power

leads.

Due to the positioning of the screws on the inside of the connectors,

it is easier to wire the connectors by first removing them and then

running the flying leads to the appropriate slots. It is recommended

that you remove only one connector at a time to avoid confusion

and reduce the possibility of error in matching the flying leads to the

correct slot on the connector.

Wiring Cable Flying Leads to the Plugs

To wire the cable leads to the plug:

1. Look at the plug to make sure the terminal is open. Figure 3

shows both an open and a closed terminal.

2. Terminal Steps

If the terminals are: Do this:

Not open Go to step 3

Terminal open

Terminal closed

3. Using a small, flat-head screwdriver, turn the clamping screw

counter-clockwise several times.

4. Using a proper stripping tool, strip the wire insulation back on

the cable lead.

5. Trim the cable lead so that 0.275 inches of metal wire is

exposed.

6. Insert the cable lead in the appropriate terminal. Refer to the

proper figures for their locations.

7. Use the screwdriver to tighten the clamping screw to the

proper torque (0.25 N-m/2.2 in-lb.).

8. Verify that the cable lead does not pull out of the terminal.

The function of these connectors, their pinouts, and names are

defined in the following sections.

Open Go to step 4

IMPORTANT

All terminals accommodate a maximum of 14 gauge

wire.

If the cable lead: Do this:

Pulls out of the terminal Repeat steps 3 through 9 again

Does not pull out of the terminal Repeat steps 3 through 9 for the

next terminal

If the terminals are: Do this:

Conductor size must not be greater than 1.5 mm

. The I/O circuits in

the PDM drive are protected by a 1 amp fuse contained in the drive.

Wiring the P2 Connector

The P2 User I/O requires a separate clean 24 volt nominal DC

supply. There is no galvanic connection from one side to the other,

and the user 24 volt supply must be grounded on the negative side

to the protective earth system. The supply should be between 20

and 30 volts DC, and should be capable of supplying the loads

imposed by the output loading plus 8 mA for each input used. It

must be fused adequately to protect the cable used. Output loads

must be connected between the output and 24 volt ground, and

must be 470 ohms or more impedance. The interface outputs are

rated at 50 mA. Cabling should be 1.5 mm maximum.

The inputs must be supplied by the users input circuit from the user

24 volt positive and each input sinks 8 mA when active.

Cables

An optional interface cable 44-0141-xxx is available which has a

shield termination eyelet for customer connection. The xxx at the

end of the cable part number defines the length of the cable in feet.

For example: 44-0141-010 is the cable in a 10 foot length. The

maximum cable length is 100 feet.
