AMI8121-ab00-wFyz | Compact integrated servo drive 0.48 Nm (M0), F2 (58 mm)
AMI8121 Compact Integrated Servo Drive BECKHOFF combines servomotor, output stage and fieldbus connection in a space-saving design in the voltage range of < 48 V DC. It is suitable for all motion requirements in the power range up to 400 W. The standstill torque of the motor is 0.5 Nm. The integrated servo drive with flange code F2 (58 mm) and motor length 1 has a shaft diameter b = 9 k6 and a free shaft end of d = 20 mm.

The TC3 Drive Manager 2 serves as commissioning tool. Thanks to the structured design and the wide range of functions, commissioning of the axis is simple and intuitive.
