Issue:
Selecting a Braking Resistor for the ATV900 Series Drives.
Product line:
Altivar Process Drive (ATV930, ATV950)
note: some ATV960 drives have an ATV930 inside the enclosure so use the ATV930 part number to determine the DB min resistance.
Environment:
Altivar Process Drive
Cause:
n/a
Resolution:
See the attached information from the 06/2022 Installation Manual for the ATV930/950 drives for minimum resistance ratings to match the correct braking resistor.
Using a resistor with lower resistance can result in damage to the drive.
