What is the maximum Ohmic value of the Braking Resistor for the Altivar 71 Drive.
The minimum Ohmic value for Braking Resistors (R)for the Altivar 71 Drive is mentioned in the catalog because if the value is too low it can damage the Braking Transistor (V=IR). The DC bus level for the braking is always the same, so if R is too low, the current increases which can damage the Braking Transistor.
But there is no maximum Ohmic value.
The Ohmic value is designed considering the average Inertia.
