Product Description:

The 167G0997 is an AC variable frequency drive produced by Danfoss for the VLT EZ FC 321 Automation Drives series. It is used to regulate motor speed and torque in conveyors, pump systems, and other factory automation equipment where adjustable motor control is needed. By varying output frequency and voltage, the drive supports stable operation across changing process demands. This type of drive is commonly used where acceleration, deceleration, and running speed must match the machine cycle instead of leaving the motor at fixed line frequency. Its chassis-mount format suits installation in panel-based control systems where space and airflow must be managed carefully.

The unit is rated for 30 HP, which corresponds to 22 kW of drive output. It operates from a three-phase 525–600 VAC mains supply, making it suitable for higher-voltage industrial power systems. That output range supports use on larger fans, pumps, and material-handling equipment that require substantial continuous power. The enclosure has an IP20 chassis protection level, so the drive is intended for installation inside a closed cabinet rather than in an exposed location. An integrated EtherNet/IP MCA 121 option provides direct network communication for diagnostics, status monitoring, and remote adjustments without requiring a separate gateway module.

For deceleration duty, the control section includes a built-in brake chopper that handles regenerative energy during braking events. This arrangement helps the drive manage short, repeated slowdowns in dynamic applications. The unit uses standard cable entries, which helps keep power and control wiring straightforward during panel installation. It has uncoated printed circuit boards, so it is better suited to clean, climate-controlled enclosures where moisture and airborne contaminants are limited. There is no local control panel, so operation and setup are handled through the network interface or other remote control methods.
