Phase current measurement:

Phase current can be determined by measuring Vref at Vref terminal. The equation to calculate the Imax is shown below

Phase current           Imax = 0.32 * Vref 
 Running current adjustment: Applying a pulse input signal to the pulse input terminal at a pulse rate higher than 10PPS. Rotate potentiometer VR1 to adjust the running current Imax. 
 Idle current adjustment: Stop the pulse input signal for more than 1 second. Rotate potentiometer VR2 to adjust the idle current Imax.
