The EJ7047 stepper motor module is designed for the direct connection of stepper motors in the medium power range up to 5 A and for a voltage range of 8…48 V. The compact stepper motor output stage is accommodated in the EtherCAT plug-in module together with two digital inputs for limit switches and an encoder interface. The second input can also be configured as an output in order to enable the use of a holding brake.
The EJ7047 can be adapted to the motor to be operated and the application requirements through parameterization. A particularly smooth and precise motor run is ensured by 64-fold microstepping.
In combination with a corresponding stepper motor, the EJ7047 represents a cost-effective compact drive solution. With its torsion-proof, integrated encoder (1,024 inc/rev), the AS2000 stepper motor is ideal for the closed-loop control of the EJ7047.
