If [Bus Reg Mode x] is set to “Both-DB 1st”
Both regulators are enabled, and the operating point of the Dynamic Brake
Regulator is lower than that of the Bus Voltage Regulator. The Bus Voltage
Regulator setpoint follows the “DB Turn On” curve. The Dynamic Brake Regulator
follows the “DB Turn On” and turn off curves. For example, with a DC Bus
Memory between 650 and 685V DC, the Bus Voltage Regulator setpoint is 758V
DC and the Dynamic Brake Regulator will turn on at 742V DC and back off at
734V DC.

Copy Cat
PowerFlex drives have a feature called Copy Cat, which provides a way to upload a
complete set of parameters to the LCD HIM. This information can then be used as
backup or can be transferred to another drive.
The transfer process manages all conflicts. If a parameter from HIM memory does
not exist in the target drive, or the value stored is out of range for the drive, or the
parameter cannot be downloaded because the drive is running, the download will
stop and a text message will be issued. The remainder of the download can then be
aborted or continued by acknowledging the discrepancy. These parameters can then
be adjusted manually.
The LCD HIM will store a number of parameter sets (memory dependent) and each
individual set can be named.
