Autonics MD2U-MD20

Unipolar constant current drive type
Enable to brake when it stops by STOP current adjustment
Insulate using photocoupler to minimize the influence by external noise
Power supply: 24-35VDC

Driver, 2 Phase Stepper, 0.5-2.0A/Phase, 20 - 35VDC, 3A, Unipolar, 40K pps, Microstep

The MD2 series 2-phase stepper motor drivers allow extremely precise motor control with low mechanical noise and low vibration operation. The isolated photocoupler input design minimizes influence from electrical noise. Low vibration operation is possible with the microstepping drive function (MD2U-MD20).

1: When using over 30VDC power supply, torque characteristics are improved but the driver temperature raise. The unit should be installed at the well ventilation environment. 2: Based on ambient temperature 25 °C , ambient humidity 55%RH. 3: RUN current varies depending on the input RUN frequency and max. RUN current at the moment also varies depending on the load. 4: Max. input pulse frequency is max. frequency to be input and is not same as max. pull-out frequency or max. slewing frequency . 5: The weight includes packaging. The weight in parentheses is for unit only . Environment resistance is rated at no freezing or condensation.
