3-PHASE BRUSHLESS DC
MOTOR CONTROLLER/DRIVER
115 Northeast Cutoff, Box 15036
Worcester, Massachusetts 01615-0036 (508) 853-5000
D0- Sleep/Run Mode; LOW = Sleep, HIGH = Run
This bit allows the device to be powered down when not in
use.
D1- Step Mode; LOW = Normal Operation, HIGH = Step Only
When in the step-only mode the back-EMF commutation
circuitry is disabled and the power outputs are commutated
by the start-up oscillator. This mode is intended for device
and system testing.
D2- Brake; LOW = Run, HIGH = Brake.
D3 and D4-These two bits set the output current limit:
