EL7047 | Stepper motor terminal 50 V DC, 5 A,
with incremental encoder, vector control

The EL7047 EtherCAT Terminal is intended for stepper motors with medium performance range. The PWM output stages cover a wide range of voltages and currents. Together with two inputs for limit switches, they are located in the EtherCAT Terminal. The EL7047 can be adjusted to the motor and the application by changing just a few parameters. With its torsion-proof, integrated encoder (1,024 inc/rev), the AS2000 stepper motor is ideal for the closed-loop control of the EL7047.

The output power of the terminal can be further increased when used with the ZB8610 fan cartridge (continuous operation and under full load).
