Rockwell Automation 8720MC 8720MC Regenerative Power Supply User Manual - Manual (Page 95)

Factory parameter values are password protected using Parameter
F.000 (Setting Password). But even after the password has been
set, some Factory parameters cannot be modified. Such parameters
must be set after operation stopped.
Note that Parameter F.018 (Version Information) is a read-only
parameter, and therefore, cannot be modified.
ATTENTION: Only qualified electrical personnel
familiar with the construction and operation of this
equipment and the hazards involved should change
the Factory Parameters. Read and understand this
instruction manual in its entirety before proceeding.
Failure to change parameter values could result in
destruction of the equipment, severe bodily injury or
loss of life.
To display or change parameter values, the operation panel must be
in program mode. Use the procedure described in the following
sections to change parameters in program mode. For calling out the
error log and resetting faults, refer to Chapter 9.
The User parameters contain basic parameters that are modified
depending on applications of the 8720MC-RPS Regenerative Power
Supply. Use the following procedure to modify the User
parameters.
Step 1. Press the PRG key until the "PROGRAM" status LED
turns ON and the display shows "U.---". You can access
the User parameters. If "U.---" is not shown on the
display, press the
key or the key until "U.---"
appears on the display.
Step 2. Press the ENT key. The first User parameter number
(U.000) will be displayed.
Step 3. Use the key or the key to move through the User
parameters.
Step 4. When the desired parameter appears, press the ENT key.
The parameter will be called out, and the parameter value
will be displayed.
Step 5. Use the
key to increment the value and the key to
decrement the value.
Step 6. Press the ENT key to save changed value. Pressing the
ENT key will display the same parameter number again,
indicating that the value was saved.
Note 1: The value is not written to the memory until the ENT key
has been pressed.
Note 2: Pressing the PRG key will also return to the same
parameter number, without saving the value.
Parameter values are retained through a line dip or power
shutdown.
