Security
The Security feature provides drive access protection.
Ports
This feature provides write access protection for individual communication ports
in the drive. The HIM or communication modules with software tools can be
used to change any port to read only.
A password can also be used with the HIM to prevent writing to parameters
through the keypad. See
.
The following drive peripherals can be used to control access.
•
20-HIM-A6 or 20-HIM-C6S keypads
•
20-750-
n and 20-COMM-n communication options
•
20-COMM-
n legacy communication options
Refer to the PowerFlex 750-Series AC Drives Technical Data, publication
for suitability and details.
The following software tools can be used to control access.
•
Connected Components Workbench (CCW) version 2.0 or later
(freeware)
•
Drive Explorer version 6.04.99 (freeware)
•
Drive Executive version 5.03 or later
By default, every DPI port in the drive is configured to allow read and write
access.
To change the write access on an individual DPI port, change the bit setting of
the associated port in P888 [Write Mask Cfg]. Changing the bit value from 1
(read/write) to 0 with a HIM provides read only capability. Using software such
as Drive Explorer, Drive Executive, or CCW can also be used to turn the bit off.
Below is an example of using CCW to change port 4 to read only.
