6 IF2 I/O Interface to PDM

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.

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.

Terminal closed
2. Terminal Steps
If the terminals are: Do this:
Not open Go to step 3
Publication 4100-IN001A-EN-P- February 2001
IF2 I/O Interface to PDM 9
If the terminals are: Do this:
Open Go to step 4
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.
IMPORTANT
All terminals accommodate a maximum of 14 gauge wire.
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.
9.
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
The function of these connectors, their pinouts, and names are defined in the following sections.

IF2 I/O Interface to PDM 11
Conductor size must not be greater than 1.5 mm2. 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.
