Description 

The 20-750-20COMM is an Allen-Bradley carrier card. This card enables an obsolete 20-COMM communication adapter, of any supported protocol, to be installed to a PowerFlex 750 Adjustable Frequency AC drive. This carrier card is compatible with 20-COMM-B, 20-COMM-C, 20-COMM-D, 20-COMM-E, 20-COMM-H, 20-COMM-K, 20-COMM-L, 20-COMM-M, 20-COMM-P, 20-COMM-Q, 20-COMM-R, and 20-COMM-S. This carries card may be installed with PowerFlex 750 Frame A2 and higher.

Technical Specifications 

Information About 20-750-20COMM

The Allen-Bradley 20-750-20COMM is a carrier card that is manufactured by Allen-Bradley. This card is used to enable support with legacy and obsolete communication adapters for use with the PowerFlex 750 class drives, specifically, PowerFlex 753 and PowerFlex 755. This carrier card may only be used with PowerFlex 750 Frame 2 and larger drives.

The 20-750-20COMM supports a variety of communication adapters such as 20-COMM-C ControlNet (Coax) communication adapter Versions v3.001; , 20-COMM-D DeviceNet adapter; 20-COMM-E Ethernet I/P adapter; 20-COMM-H RS-485 HVAC adapter v2.009; 20-COMM-K Version v1.001 CANOpen adapter; 20-COMM-L version v1.007 LONWORKS adapter; 20-COMM-M v2.001 MODBUS TCP adapter; 20-COMM-P version v1.006 ControlNet (Fiber) adapter; 20-COMM-Q v3.001 Profubus DP adapter; 20-COMM-R Remote I/O adapter and 20-COMM-S RS485 DF1 communication adapter.

Specific Asian language support includes Chinese, Japanese and Korean languages.

The carries card, due to its larger size, is recommended to be installed in Port 6. It may also be installed in Port 4 or 5, however, the adjacent ports will become unavailable as this carrier card will cover the slot. With Port 6, this can be avoided. Additionally, installation to Port 6 prevent communication interference.

PowerFlex 753 drives provide control for applications requiring a maximum of 400 Horsepower (270 kilowatts). PowerFlex 755 drives provide control for applications requiring a maximum of 2000 Horsepower (1500 kilowatts). For frame 2 and larger drives, Allen-Bradley recommends that the 20-750-20COMM card be installed in Port 6 because the use of Port 4 or 5 will make the adjacent port inaccessible to other option modules and it can also interfere with network cable connections. Legacy communication modules which require the 20-750-20COMM card to be installed in a PowerFlex 750 series drive include the 20-COMM-C module which supports ControlNet over coaxial cable, the 20-COMM-D module to enable DeviceNet communication, the 20-COMM-E module to enable Ethernet communication, the 20-COMM-H module which supports HVAC applications (only the Modbus RTU can be used), 2the 0-COMM-K module to enable CANopen communication, the 20-COMM-L module which supports LonWorks communication, the 20-COMM-M module that enables Modbus/TCP communication, the 20-COMM-P module which supports Profibus DP communication, the 20-COMM-Q module to enable ControlNet communication over fiber, the 20-COMM-R module for Remote I/O communication, and the 20-COMM-S module for RS-485 DF1 communication. The installation of a PowerFlex 750 drive which contains the 20-750-20COMM card should be avoided in hazardous environments which contain volatile or corrosive gas, vapors, and dust. Unused 20-750-20COMM card modules should be kept in storage at a temperature range of -40 to 158 degrees Fahrenheit.
