Stepper motor module 24 V DC, 1.5 A EJ7031

EJ7031 | Stepper motor module 24 V DC, 1.5 A

The EJ7031 stepper motor output stage is intended for the direct connection of different stepper motors up to 1.5 A. The slimline PWM output stages for two motor coils are located in the EtherCAT plug-in module together with two inputs for limit switches. The EJ7031 can be adjusted to the motor and the application by changing just a few parameters. 64-fold micro-stepping ensures particularly quiet and precise motor operation.
