Parker: Stepper Drive/Oscillator (OFS350-OSC)

The OFS350-OSC is a microstepping drive offering 12,800 steps per revolution, a step phase sequencer with MOSFET three-state switching amplifiers, and optoisolated circuits. The drive includes five optically isolated inputs, external speed control, tach output, and internal pots for accel/decel rate along with high- and low-speed range selection. The amplifier regulates motor current by chopping at a constant, inaudible frequency. Phase current is selected from 32 levels by a DIP switch, which also controls the microstepping resolution

OFS350-OSC Features:

• DC bus voltage 12-42 VDC motor supply (including ripple)
• Switch selectable currents from 0.4–3.5 amps/ phase motor current
