Frequently Asked Questions (FAQ)

• What is the "preferred" CM jumper installed configuration for?

Having the Common Mode (CM) jumper installed is the standard factory setting. It ensures the internal EMC filter is fully active, providing the best compliance with electromagnetic compatibility standards for typical industrial installations without creating ground loop issues.

• Can this drive operate on both 50Hz and 60Hz power systems?

Yes, the specified input frequency tolerance of 47-63 Hz means it is designed to operate on both standard 50 Hz and 60 Hz power networks without requiring parameter changes, offering global application flexibility.

• What is the advantage of having both AC and DC input terminals?

It provides application flexibility. You can power the drive from a standard AC line or connect it to a DC bus in multi-drive systems for shared braking energy. The DC terminals also allow operation from battery or renewable DC sources.

• Why is the operating temperature range limited to 0-40°C?

This is the standard ambient air temperature rating for full output current without derating. The drive can often operate at higher temperatures (up to 50°C or more) but will require output current derating as specified in the manual to prevent overheating.

• How do I monitor and control the drive without the HIM?

You can use the embedded I/O for basic start/stop and speed control. For full monitoring and parameter access, connect a computer with Connected Components Workbench (CCW) software to the drive's communication port or install an optional communication adapter and HIM.
