Motion Control • Drives
Motion control drives are used for converting standard control signals into higher powered currents and presenting these currents to the actuator. This process is performed by taking energy from a power source and keeping the output under control so that it matches the signal shape of the input (but with a higher amplitude).

National Instruments manufactures servo and stepper drives as part of their motion control line. The P70360 and NI P70530 are both 1-axis stepper drives. The P70360 525 Watt drive has 2.5 A continuous current output and 320 V bus voltage; selectable 200 to 50,000 steps/revolution microstepping, available 120 or 240 VAC powered. The 300 Watt NI P70530 features 5 A continuous, 20 to 75 V bus voltage, 7.1 A peak current output and 20 to 75 VDC input voltage.
