Stepper Motor Drive Terminals and Accessories

Connect your stepper motors directly to Kollmorgen Automation Suite controllers with these AKT2G stepper drive terminals. With no need for conventional stepper drives, you can eliminate bulky hardware and complex wiring that would otherwise be required.

Unlike analog stepper drives, these stepper drive terminals communicate digitally via the KAS EtherCAT® network. So you always know the real-time state of each stepper axis and can achieve precise, responsive control. Setup is also much easier and more reliable compared to stepper motion that relies on analog control. This terminal family works with thousands of stepper motor versions.

Stepper Motor Terminal, 24 V DC, 1.5 A, Vector Control

The AKT2G-SM-L15-000  EtherCAT Terminal is intended for the direct connection of stepper motors in the low power range up to 1.5 A and a voltage of 24 V. The compact stepper motor output stage is incorporated in the EtherCAT Terminal together with two digital inputs for limit switches. Through parameterization, the AKT2G-SM-L15-000 can be adjusted to the motor and the application requirements. 64-fold micro-stepping ensures particularly quiet and precise motor operation.

Stepper Motor Terminal, 50 V DC, 5 A, Vector Control

The AKT2G-SM-L50-000  EtherCAT Terminal is intended for the direct connection of stepper Motors in the mid power range up to 5 A and a voltage range from 8-50 V. The compact stepper motor output stage is incorporated in the EtherCAT Terminal together with two digital inputs for limit switches. Through parameterization, the AKT2G-SM-L50-000 can be adjusted to the motor and the application requirements. 64-fold micro-stepping ensures particularly quiet and precise motor operation.

Brake Chopper Terminal

The AKT2G-BRC-000-000 EtherCAT Terminal contains high-performance capacitors for stabilizing supply voltages. The AKT2G-BRC-000-000  can be used in conjunction with the AKT2G-SM-L15-000 or AKT2G-SM-L50-000 stepper motor drive terminals. Low internal resistance and high-pulsed current capability enable good buffering in parallel with a power supply unit. Regenerative currents are  accommodated preventing over voltages. If the regenerative energy exceeds the capacity of the capacitors, energy can be dissipated via an external braking resistor.
