Enhancements This section describes the enhancements included in this revision.
Scratch Pad and Scale Block Parameters for Options Developer Toolkit
This revision of drive firmware adds parameters to support the options developer
toolkit. The additions include “User Data” integer [1700-1731], “User Data”
floating point [1800-1831], and “Scale Block” integer/floating point [1900-
1931].
Drive Performance Parameter Updates
With this revision of drive firmware two parameters have been updated to
increase performance. First, the maximum limit of the “Notch Filter
Attenuation” [688] has been increased to 1000. The previous limit was 500.
Second, the maximum limit of the “Position KI Limit” [838] has been increased
to 12500. The pervious limit was 2500.
Corrected Anomalies This section describes the anomalies corrected in this revision.
High Torque with IPM Motors
This revision of drive firmware increases the max allowable percentage of motor
toque for IPM motors. The calculation for torque in previous firmware revisions
did not accommodate for the derived formula used with IPM motors which have
different dand qinductance values. This limited the max percentage of motor
torque that could be applied to 150%. With this release of drive firmware, the
derived calculation for IPM motors has been updated to enable IPM motors to
calculate up to 250% of motor torque within the drive.
Fatal Exception 917 for Low Power Drives
A fatal 917 exception is a FPGA CRC fault. This fault occurs when the FPGA
on the main control board experiences a soft error and is in place to prevent
potential changes in drive performance. Previous revisions of drive firmware
would require a power cycle of the drive when the fault occurs. With this revision
of drive firmware the default fault behavior remains the same, but can be
configured if the default behavior is undesirable. The “CRC Fault Config” [964]
parameter can be configured as a response to this drive behavior.

PowerFlex 753 Drives (revision 10.003)
DeviceLogix Parameters not Updating
This revision of drive firmware resolves an anomaly within DeviceLogix where
parameters display an incorrect value for short period of time. When this
behavior occurs the parameter value will show correctly, then switch to an
incorrect value, then back to the correct value.
Drive Behavior when a Reverse Commanded is given at Zero Speed
This revision of drive firmware resolves an anomaly when a reverse command is
given and the drive is at zero speed. In previous firmware revisions, when the
drive is given a run reverse command and a zero speed command the drive would
run forward at the minimum speed. The drive will now use the sign bit of the
speed command to determine the minimum value it shall use.
Inertia Compensation with Current Limit Stop
This revision of drive firmware resolves an anomaly when using inertia
compensation, a current limit stop, and the drive is in an I/O connection. In
previous revisions of drive firmware, when “Inertia Compensation LPFBW”
[698] is set to 0 the inertia compensation would become unstable on a current
limit stop and may not always ramp to 0. This revision of drive firmware corrects
this behavior to ensure the current limit stop ramps to 0 under the condition
previously described.
PTC Status on 22-Series I/O Cards
This revision of drive firmware resolves an issue with the 22-Series I/O option
cards more specifically the PTC function. The “PTC Status” [P41] has three
different status configurations that are dependent on the PTC voltage threshold.
The behavior of the PTC status has been updated to properly align with the
engineering thresholds.
Automatic and Manual Speed Reference During Comm Loss
This revision of drive firmware corrects an anomaly when a “Comm Loss” fault
occurs and a communication card is in port 6 of the drive and in manual mode.
Previously, when the fault occurred and the communication card switched the
command to an automatic mode, but the reference would remain in manual
mode with port 6. With this revision of drive firmware the logic has been
corrected to allow the control of the reference to switch to automatic mode when
a “Comm Loss” fault occurs.

PowerFlex 753 Drives (revision 10.003)
Start Command with Manual Speed Reference and Configured Digital
Input
This revision of drive firmware corrects an anomaly when a drive has a
communication card in port 6 and configured in manual mode and a start
command is given with a digital input configured for run level. This revision of
drive firmware has corrected the drive logic to allow the communicated
command word to start drive in manual mode when there is a discrete digital
input configured for run level.

PowerFlex 753 Drives (revision 10.003)
Known Anomalies This section describes the known anomalies that are present in this revision.
Feedback Selection
The HIM startup on the PowerFlex 753 drive includes a feedback device
selection step. Depending on the option modules installed, that step may first ask
the user to choose a port, then a parameter. In some situations, the list of ports
incorrectly shows multiple copies of “Port 0 - PowerFlex 753” followed by the
feedback port/module.
The incorrect behavior happens only under the following conditions:
•It is the first time that startup feedback selection has been run since
flashing the drive.
•The feedback module is a dual encoder or UFB and no other option
modules are installed.
•A reset to defaults of the drive NVS parameters has not been performed
since the drive was last flashed.
When the incorrect port list appears, it is still possible to successfully select the
feedback module port by following one of these methods.
•Scroll past the multiple copies of Port 0 to reach the desired feedback
module.
•Press the Esc soft key to back up one screen, then select “Feedback” and
press the Enter soft key to display the port selection screen a second time.
This time the correct list will be shown.
Persistent Stop Command with Profile Message Fault Action
In an application with the use of a PowerFlex 753 along with the 20-750-ENETR
dual port Ethernet/IP module, a persistent stop command may appear in some
cases. The action of disconnecting the Ethernet cable from the 20-750-ENETR
module, which will result in the drive stopping, may follow with a nuisance fault
action. This fault action previously noted is persistent communication of stop
commands.
Saving Parameters using Drive Explorer
In an application with the use of a PowerFlex 753 along with the 20-750-ENETR
dual port Ethernet/IP module, in which a user attempts to save all parameters
using Drive Explorer in some causes the save execution does not complete. When
attempting to execute the save all parameters in Drive Explorer the software tool
enters an infinite loop and does not progress through the save in some instances.
To exit the loop, press the cancel button and check if the text file has been saved.

PowerFlex 753 Drives (revision 10.003)
Restrictions and Compatible
Revisions
The following restrictions apply to this revision of firmware.
Max Output Frequency Limited to 590Hz
This revision of drive firmware places a limit on the maximum output frequency
of the drive. In previous versions of drive firmware the maximum operating
frequency of the drive was 650Hz. The new maximum output frequency limit is
590Hz. If a previous application allows for a maximum output frequency greater
than 590Hz, the drive will ramp to the command frequency set point and once it
reaches a value greater than 590Hz for a period of time greater than 16ms the
drive will trip on a Fault 31, “Over-Freq”.
Implementation of Secure Flash
With this revision of drive firmware, an encryption layer with digital signature
has been attached to the drive firmware flash file. This encryption layer will not
allow the flashing of firmware files that have not been digitally signed by
Rockwell Automation. When flashing from a revision of firmware that is not
digitally signed, users will first need to flash up to V11.001 to enable the secure
flash feature to read the digital signature. Once at V11.001, a customer can flash
to any desired firmware revision level that has a secure digital signature. Previous
versions of drive firmware that don’t have a secure digital signature embedded in
the flash file will display the error shown below when a flash is attempted.
EtherNet/IP Port and 20-750-ENETR Require Quality of Service (QoS)
With this firmware revision, the EtherNet/IP port and 20-750-ENETR require
the EtherNet/IP scanner to use a compatible method of specifying Quality of
Service (QoS). The following table details the compatible products and firmware
revisions.
