Drives Service & Support > PowerFlex 700S Phase II control > FAQ

1. What are the differences between the existing PowerFlex 700S Phase I control and the new Phase II control hardware?

The new Phase II control hardware takes advantage of newer processor designs, producing significant performance improvements over the Phase I control hardware design. In addition, the new control hardware has been architected to allow a higher degree of scalability than possible with the Phase I control hardware design.

Also, the Phase I control Assembly is no longer required with the Phase II control hardware. Instead, the standard PF700 control cassette is used to house the control hardware. An expanded version will be offered as the standard configuration, but the slim (same width as the PF700 cassette) is available as an option.

2. How much better is the Phase II control performance?

All the regulator and motor control scan times have been cut in half as shown below.

In addition, the PowerFlex 700 vector encoderless algorithm has been incorporated into the Phase II design, providing the best in encoderless operation.

3. Can a PowerFlex 700S equipped with Phase I control hardware be field upgraded to the Phase II control hardware?

Yes. Simply remove the Phase I control assembly and cassette, and replace with the Phase II control cassette. There is no need to remove the base plate, however, to take full advantage of the package size improvements, the base plate should be removed and the drive remounted.

4. Does the Phase II control have all of the same functionality as the Phase I control?

Yes. All Phase I functionality is present in the Phase II control feature set. In addition, there are many new features and functionality including: selectable scan times, more user functions, increased stand-alone positioning capability and more.

5. Are all of the parameters the same in the Phase I and Phase II control?

Where possible, the parameters are the same. However, a great deal of effort was devoted to reducing the number of parameters and making the Phase II control much easier to use. Changes were made to bring the PowerFlex 700S more in line with the PowerFlex 700, reduce parameter overlap and add new functionality.

6. How many parameters make up the PowerFlex 700S Phase II control?

There are many features and function available with the PowerFlex 700S. Because of this, the total number of parameters is greater than the PowerFlex 70 and 700 drives. The number of parameters has been reduced by 20% as compared to the Phase I control. Additionally, a number of methods are used to restrict parameter visibility to the user. The newest and most innovative approach to reducing the number of parameters visible to the user is accomplished by hiding the parameters associated with un-used functions. There are (2) parameter access levels that allow parameter visibility via the HIM to be controlled: Basic and Advanced. The Basic access level includes all parameters previously found in Basic and Advanced levels of Phase I control. The File/Group/Parameter structure groups parameters functionally such that parameters for unused functions do not have to be viewed.

7. Does the Phase II PowerFlex 700S control include an option for AC I/O?

Yes, (3) of the Inputs can be configured for 120 VAC via a DIP switch. One of these (3) inputs may be used as the hardware enable input. These inputs come factory set for 24VDC. In addition, the form-C relay output is dual rated for 24VDC and 120VAC.

8. Does the Phase II control still have a dedicated enable input?

Yes, digital input 6 is factory set as the hardware enable. However, the user now has the option, via a hardware jumper, to make digital input 6 configurable. This is consistent with the approach used on the PowerFlex 700 with vector control.

9. Will a conversion tool be available to convert existing Phase I parameter files to Phase II?

Yes. A conversion utility will be included in the version 3.02 DriveExecutive software patch. The conversion utility will be similar to the utility provided to convert from the PowerFlex 700 standard to vector.

10. Will a conversion guide be available to convert existing Phase I drive to Phase II?

Yes. A conversion guide will be available outlining control connection changes between Phase I and Phase II control. Also, the parameter changes will be outlined showing the individual change and overall group moves that have occurred.

11. What are the differences between the DriveLogix5730 and DriveLogix5720?

The new DriveLogix5730 is based off of the CompactLogix 1769-L35E design. DriveLogix5720 is based of the FlexLogix design. By using the CompactLogix design, DriveLogix now benefits from a newer processor design including on-board floating point processors. Consistent with the scalable PowerFlex 700S Phase II design, DriveLogix5730 has been architected to allow a higher degree of scalability than possible with the DriveLogix5720 design.

12. Can DriveLogix be field installed into a PowerFlex 700S Phase II?

Yes. Because DriveLogix and the PowerFlex 700S are on the same circuit board, the existing PowerFlex 700S cassette must be replaced with a new cassette containing the PowerFlex 700S Phase II control with DriveLogix.

13. What networks does DriveLogix5730 support?

DriveLogix now supports an optional embedded EtherNet/IP communication daughtercard, and with the optional Logix expansion board, DriveLogix supports the same communication daughter boards as FlexLogix. These include ControlNet COAX (1788-CNC(R)) and fiber (1788-CNF(R)), DeviceNet (1788-DNBO) and EtherNet/IP (1788-ENBT). Third party network support also includes Profibus master and slave. This means DriveLogix now can supports up to (2) network connections!

14. What options will fit in the Slim cassette (same width as the PF700 cassette)?

The base DriveLogix5730 with 1.5 Mbytes, Serial port, 3-position Run/Remote/Prog switch, and the optional embedded EtherNet/IP card will fit in the slim cassette.

15. What is the Logix Expansion Board?

As an option, the Logix Expansion board offers (1) communication daughter board slot (for 1788- cards), a connection for local Compact I/O and a slot for CompactFlash removable flash memory. The Logix Expansion board requires the Expanded cassette and only works when DriveLogix is installed.

16. What CompactFlash features does the DriveLogix5730 support?

• The ability to Store the User program on Flash and restore based on bad memory, power up, or user initiated.
• The ability to store the processor’s firmware along with the user program on Flash. If the processor’s firmware does not match the CompactFlash program, the processor will be automatically updated with the firmware on the flash media. Flashing the processor’s firmware takes around 30 additional seconds.
• New for v13, the ability to store and retrieve tag data on the CompactFlash card. This data is stored/retrieved using common CIP messages. To simplify the process, example code is provided on the v13 RSLogix5000 CD.
• The CompactFlash card is formatted FAT32. The user can archive other system files, such as HMI applications, ACAD drawings, etc to a new directory on the flash.

17. What level of Ethernet does the embedded card support?

The DriveLogix embedded EtherNet/IP card has the same 10/100 Mbytes Ethernet port as the 1769-L32E and 1769-L35E CompactLogix controllers. The EtherNet/IP port supports up to 32 simultaneous CIP connections. These 32 CIP connections can be used for Distributed EtherNet/IP I/O, Real-time data interlocking with other EtherNet/IP controllers (i.e. ControlLogix w/ 1756-ENBT), and high-speed data sharing to HMI devices (i.e. RSView).
In addition, the high performance EtherNet/IP port enables high speed upload/downloads, online program configurations, and advanced TCP/IP web services, such as Email.

18. What new Web Services does the embedded card provide?

The DriveLogix controller, when equipped with the embedded EtherNet/IP option, can format and send email messages via the TCP/IP Ethernet port. The email message is sent via a generic message instruction. The user can permanently store a receipt address on the controller or dynamically change the email receipts programmatically.

19. Does DriveLogix5730 require a battery for memory retention?

Yes, DriveLogix ships with a lithium battery. This battery (1769-BA) provides up to 8 months of memory retention at 60° Celsius. The battery retains user memory and the data values of all tags at the time of the power off condition.
The user program could be stored on the CompactFlash card and the battery removed if the processor is going to be left powered-off for prolonged periods or retention of the dynamic data values is not critical.

20. Does DriveLogix5730 support multiple programming languages?

Yes. By utilizing the Logix5000 control engine and RSLogix 5000 programming software, DriveLogix is able to completely support ladder diagram (LD), structured text (ST), sequential function chart (SFC) and function block diagram (FBD) programming languages.

21. Does DriveLogix5730 support Logix motion?

Yes. The same motion capability of the DriveLogix5720 controller is supported by the DriveLogix5730. However, the DriveLogix5730 will have a significant performance advantage over the DriveLogix5720.
