FAQ

Can I use the VW3A7702 with a modern Altivar Process (ATV600/900) drive?

No, this resistor is specifically sized and designed for the electrical characteristics of the older Altivar 61 and Altivar 71 drive series. Using it with other drives is not recommended and may cause system faults or damage.

What is the minimum mounting clearance required for this resistor?

To ensure proper heat dissipation and prevent overheating, it is crucial to mount this resistor with adequate clearance. A minimum of 100mm (4 inches) of free air space on all sides is generally recommended. Always consult the drive’s installation manual for specific guidelines.

What happens if I use a resistor with a lower Ohmic value than specified for my drive?

Using a resistor with a lower resistance value than recommended can lead to excessive current flowing through the drive’s braking chopper (transistor). This overcurrent can cause permanent damage to the drive.
