EP7047-0032 | Stepper motor box with incremental encoder, suitable for STO applications, vector control, 48 V DC, 5 A

The EP7047-0032 EtherCAT Box is intended for stepper motors in the medium performance range. The PWM output stages cover a wide range of voltages and currents. Together with two inputs for limit switches, they are integrated in the EtherCAT Box. The EP7047-0032 can be adjusted to the individual motor and application by changing just a few parameters. The module is ideal for closed-loop control of the AS2000 stepper motors, which are equipped with a torsion-proof, integrated encoder (1024 inc/rev). Either a 5 V or a 24 V version can be used as the single-ended encoder.

The STO function according to EN 61800-5-2 can be implemented with the aid of the non-reactive HWE input according to a safety level Cat. 3, PL d according to DIN EN ISO 13849-1:2015.
