Product Description
The Beckhoff EL7221-9014 EtherCAT servomotor terminal is a compact and high-performance solution designed for precise motor control in industrial automation. Beckhoff, a well-known manufacturer in the field of automation technology, created the EL7221-9014 for seamless integration into dynamic motion control systems. This terminal supports synchronous three-phase motors with permanent magnet excitation to make it ideal for demanding applications that require high precision and safety.
The EL7221-9014 operates on a 48 V DC external power supply for motor control and 24 V DC via power contacts for its electronics. To ensure smooth motor performance, the servo motor delivers precise and dynamic control with a 16kHz clock frequency and a current controller frequency of 32 kHz. Beckhoff's OCT combines power and feedback into a single cable, makes installation simpler and is included on the terminal. The terminal has two inputs for end position switches, one input for motor feedback, an STO input for safe torque off STO functions, and an output for a 24 V DC motor brake. The brake output can handle up to 0.5 A. The rotating field frequency of the terminal ranges from 0 to 599 Hz to allow for flexible control of different motor speeds.
The EL7221-9014 EtherCAT servomotor terminal supports distributed clocks that enable precise synchronization in EtherCAT networks. The terminal features a 500 V electrical isolation between the E-bus and field potential to enhance system safety. The terminal consumes approximately 120 mA from the E-bus and around 100 mA plus the holding current from the power contacts. Weighing approximately 95 g, the compact design allows for efficient space utilization. Beckhoff's integrated electronic type plate enables automatic motor parameter configuration that further reduces the setup time.
