EL7037 | Stepper motor terminal 24 V DC, 1.5 A, with incremental encoder, vector control

The EL7037 EtherCAT Terminal is intended for stepper motors with low 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 EL7037 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 EL7037.
