EL6751 is an EL6xxx series master terminal manufactured by Beckhoff. This terminal weighs approx. 70 g, operates at a temperature range of -25 to +60 degrees Celsius, and its current consumption (from the E-bus) is typ. 230 mA. It is widely used in Homag woodworking machine.

• All CANopen PDO communication types are supported: event driven, time driven (using an event timer), synchronous, polling.
• synchronization with the PC controller's task cycle
• SYNC cycle with quartz precision for drive synchronization, zero cumulative jitter
• parameter communication (SDO) at start-up and when running
• emergency message handling, guarding and heartbeat
• powerful parameter and diagnostics interfaces
• online bus load display
