AKT2G-SM-L50-000
Stepper motor terminal, 50 V DC, 5 A, vector control
The AKT2G-SM-L50 EtherCAT
***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs 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.
