Stepper motor module 50 V DC, 5 A, with incremental encoder, vector control EJ7047

EJ7047 | Stepper motor module 50 V DC, 5 A, with incremental encoder, vector control

The EJ7047 EtherCAT plug-in module 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 plug-in module. The second input can also be configured as an output, thus enabling the use of a holding brake.

The EJ7047 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 EJ7047.
