Same dynamic resistors on the ATV58 as the ATV66, ATV16 and ATV18.
Yes. Actual DB resistor used depends on the application. The installation guide for the drive shows the minimum Ohms value to be used. The wattage or continuous current rating of the resistor depends on mechanical considerations.
The optional parts list shows the same DB resistor part numbers for the ATV58 as used with the ATV66.
