Can a dynamic braking resistor be used with an ATV6xx Process Drive?

Issue:
Is it possible to use a Dynamic Braking Resistor with an ATV630 Process Drive?

Product Line:
Altivar 630, 660, 680

Environment:
All

Cause:
 Application requires the use of a braking resistor

Resolution:
A dynamic braking resistor cannot be used with an ATV6xx Process Drive. There is no access to the DC bus terminals (PA+ and PC-), and there is no PB terminal. 
At this point in time this is the only drive line that cannot be connected to a braking resistor. On most other drives you would normally wire a braking resistor to the PA and PB terminals. 
If a braking resistor is needed, consider using an ATV9xx Process Drive instead.
