Frequently Asked Questions (FAQ)

• What does "Normal Duty" vs. "Heavy Duty" mean for this drive?

Normal Duty (ND) ratings are for typical variable torque loads like fans and pumps, allowing higher horsepower. Heavy Duty (HD) ratings are for constant torque, high-cycling applications like conveyors, which require more thermal capacity at a lower horsepower.

• Why is the Common Mode Jumper removed on this model?

Removing the CM jumper is a specific configuration for installations where you are using an external RFI filter or have special grounding requirements to meet stringent EMC standards. It helps manage common-mode noise currents in the system.

• Can I run a 480V motor directly on 400V supply with this drive?

No, the input voltage must match the drive's rating. This 480V AC drive requires a 480V (+10%/-10%) supply. Running it on 400V will cause an undervoltage fault. You must select a drive model rated for your specific supply voltage.

• How do I program the drive without the Human Interface Module (HIM)?

You can use Rockwell's Connected Components Workbench (CCW) software free of charge. Connect a computer to the drive's embedded serial port (DSI) using a 1203-USB or similar communication cable to configure all parameters.

• Is the internal DB transistor sufficient for my high-inertia stopping application?

The internal transistor can handle moderate braking energy. For high inertia or rapid cycle braking, you must connect an external braking resistor to the drive's DB terminals. The drive will calculate and display braking resistor requirements during setup.
