  • Page 5: About This Manual

    Audience. This manual explains the installation and operation of AMCI’s 4402. It is written for the engineer responsible for incorporating the 4402 into a design as well as the individual responsible for its actual installation.

     If you need to install and use the 4402, then the rest of the manual is written for you. To simplify instal- lation and configuration, the rest of the manual is broken down into tasks and references. Using the 4402 requires you to complete four tasks, and the manual is broken down into sections that explain how to complete each one.

    PWM Outputs Two outputs are available on the 4402. These outputs have independent PWM frequency and duty cycle set- tings. The PWM frequency settings are programmable over a 1 Hz to 20 kHz range with a resolution of 1 Hz.

    Programming the Module The 4402 is typically written to by the host at a defined RPI time. In order to control the flow of programming data, the 4402 defines a Transmit Bit and an Acknowledge Bit to control a handshaking protocol called a Pro- gramming Cycle.

    Dithering is controlled with two parameters. Dither Frequency The 4402 has two Dither Frequency parameters, one associated with each channel. This parameter sets the frequency of the imposed AC signal. It has a range of 0 Hz to {PWM Frequency}/4. If the Dither Frequency is set to zero, the dithering functionality is disabled for that channel and the Dither Deviation parameter for that channel must also equal zero.

  • Page 12: Dither Deviation

    Dithering Control (continued) Dither Deviation The 4402 has two Dither Deviation parameters, one for each channel. Like Duty Cycle, Dither Deviation is programmed as an integer value that represents a percentage of the programmed time period. The value has a resolution of 0.1%.

    Disabled Table 1 Factory Default Settings With these settings, the 4402 will output at 10% on both channels, with a maximum update time of forty mil- liseconds (1/250 Hz). All of these parameters can be programmed through the network data and saved to the Flash memory on the 4402.

    If you attempt to drive more than five mod- ules, the voltage at the sixth module will be too low for the 4402 or 4402-12 module to operate. It is possible to add more 4402 or 4402-12 modules to the POINT I/O base by adding a 1734-EP24DC sup- ply to the system.

    1.4.2 Installation 1) Verify that the wiring base is correctly keyed for the 4402 module. If it is not, use a small bladed screwdriver to rotate the keyswitch on the mounting base until it matches the keying on the 4402 module.

    1.6 Power and Output Wiring Figure 1.1 below show that the 4402 obtains its 24 Vdc power from the 24 Vdc supply that is used to power the POINT I/O drop. The 4402 can source 1.5 A per output, 2.5 A per module @ 25°C. This current load must be considered when designing the system to assure that the 10 A maximum load on the internal bus is not exceeded.

    Configuration Table 2.1 CompactLogix 5370 Connection Parameters 7) Click on Next and select the RPI time. The minimum RPI time for the 4402 is two milliseconds, with five milliseconds or above recommended. The 4402 module will now appear in the project tree and three new data tags will have been created, Local:X.I.Data[Y], Local:X.O.Data[Y] and Local:X.C.Data[Y] where "X"...

    In this procedure, you will set two RPI times. The RPI time for the adapter controls how quickly discrete I/O points attached to the adapter are updated. This RPI time is not used by the 4402 but must still be set. The RPI time of the 4402 controls the rate of updates to the module.

    Table 2.2 CompactLogix 5370 Connection Parameters 13) Click on the [Next] button and select the RPI time. Because the AMCI 4402 is a Specialty I/O module, it will only use direct connections to communicate with the scanner module. Although any value down to three milliseconds can be selected, AMCI does not recommend values below ten milliseconds.
