External Shunt Resistance
Enter the resistance of the external resistor connected to the drive terminal
block connections, BR1 and BR2. Verify that the resistance is equal to or
greater than the minimum resistance for the drive capabilities. See
“Minimum Dynamic Brake Resistance” in the PowerFlex 750-Series AC Drives

.
External Shunt Power
Enter the continuous power dissipation rating (kW) of the external resistor.
Failure to specify the correct value can cause the drive to either stop sending
energy to the resistor prematurely or overheat the resistor. For example, if an
800 W rated resistor is installed, enter 0.8 in this field.
External Shunt Pulse
Power
The Watt-Second or Joules rating (kW) of the resistor. This is the amount of
energy that the resistor can withstand for one second to reach the maximum
temperature. Failure to specify the correct value can cause the drive to either
stop sending energy to the resistor prematurely or overheat the resistor.
