AKT2G-SM-L50-000
Stepper motor terminal, 50 V DC, 5 A, vector control
The AKT2G-SM-L50 EtherCAT Terminal 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 Terminal.
The SM-L50 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. Together with a stepper motor and an encoder, the SM-L50 represents an inexpensive small servo axis.
The LEDs indicate status, warning and error messages as well as possibly active limitations.
