Braking resistor terminals connected to on the ATV61/71 drives. Product Line:
Altivar 61, Altivar 71 Environment:
All ATV61's and ATV71's up to Frame size 12 Cause:
A braking resistor should be connected to terminals PA+ and PB on all VFDs up to frame size 12. Frame sizes 13 and higher require a brake transistor.
