The Beckhoff EL7047 Compact Drive Technology terminal is engineered to control 2-phase stepper motors in both uni- and bipolar configurations. It operates with a power supply of 8–48 V DC and delivers up to 5.0 A output current, extendable to 6.5 A when used with the optional ZB8610 fan cartridge. Featuring a current controller frequency of 30 kHz, step frequencies up to 16,000 full steps/s, and 64-fold microstepping, it ensures smooth motor operation and high-resolution control of around 5000 positions per revolution. Integrated encoder inputs with A, B, C, and latch signals handle up to 400,000 increments/s, providing precise feedback for motion control. Additional functionality such as travel distance control, vector control, and distributed clocks make it highly suitable for synchronized and dynamic automation tasks.
Durability and safety are core features of this Compact Drive terminal. It is equipped with 500 V electrical isolation for safe operation, EMC compliance to EN 61000-6-2/6-4, and CE and UL certifications. Its compact polycarbonate housing (24 × 100 × 68 mm, approx. 90 g) fits seamlessly onto DIN rails, while IP20 protection ensures secure operation in cabinet environments. Designed to work in operating temperatures of 0–55°C and storage down to -25°C, the EL7047 can reliably function in most industrial environments. Clear signal LEDs and pluggable wiring support quick diagnostics and simplified maintenance.
