ASI8121-abcc-w2yz | Compact integrated stepper motor drive 0.75 Nm (MH), N2 (NEMA23/56 mm)
ASI8121-abcc-w2yz | Compact integrated stepper motor drive 0.75 Nm (MH), N2 (NEMA23/56 mm)
A compact stepper motor drive for control cabinet-free machinery
Stepper motor drives with integrated servo drive
The integrated ASI8121 stepper motor drive combines stepper motor, output stage and fieldbus connection in a space-saving design in the voltage range of up to 48 V DC. It is suitable for all motion requirements in the power range up to 250 W. The standstill torque of the motor is 0.75 Nm. The integrated stepper motor drive with flange code N2 (56 mm) and motor length 1 has a stepper motor typical shaft diameter b = 8 mm with a flat and a free shaft end of d = 20.6 mm.
The TwinCAT 3 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.
