I'm installed a Powerflex 700 in place of a 1336F drive, but I'm still using the 1336F braking chopper with a same brake resistors. On the Powerflex 700, theres a parameter for choosing an external resistor. Would this be selected only if I'm using the Powerflex as it's own chopper and wiring the resistor to BR1/BR2? Since I have the 1336 Chopper wired into DC+/- on the Powerflex should I have the DC Bus Reg Mode A/B set to Dynamic Brak with external resistor type?
