OFD - Open Frame Drive

OFD - Open Frame Drive

The Open Frame Drive is a servo drive consisting of a single, low-cost board combining Power and Digital electronics and is designed to meet customer-specific cost, function and dimension requirements.
The servo drive is designed to provide up to 12A RMS continuous current from a 160 to 325 VDC bus. It can work in both Torque and Velocity operation modes. Serial communication is supported via RS232. The drive enables the OEM to control pressure process, provides real-time monitoring LCD Display support and other programming maintenance tools. The drive is mounted inside an enclosure that also houses the machine's display panel.
