What is the minimum Ohms for DB resistor for Altivar 71 drives?

Altivar 71 DB minimum resistor

Product Line:


DB resistor

Minimum Ohms value for DB resistors varies depending on the power and voltage rating of the drives.
It is acceptable to use Dynamic Brake resistor values equal to or greater than the minimum values.
Do not use resistor values less than the minimum ohms listed.
Wattage depends on the desired duty cycle.
See information in the Altivar 71 Catalog and Installation guides for more details.
