Irun[3:0] Current amplitude value to be fed to
each coil of the stepper ? motor. The table below
provides the 16 possible values for <IRUN> .
Note: When the motor is stopped, the current is reduced
from <IRUN> to <IHOLD> . In the case of 0 mA hold
current (1111 in the hold current table), the following
sequence is applied:

1. The current is first reduced to 59 mA
(corresponding to 0000 value in the table).
2. The PWM regulator is switched off; the bottom
transistors of the bridges are grounded.

Shaft This bit distinguishes between a clock ? wise
or counter ? clock ? wise rotation. The shaft bit is
not working in RunVelocity mode.
SecPos[10:2] Secure Position of the
stepper ? motor. This is the position to which the
motor is driven in case of a LIN communication
loss or when the LIN error ? counter overflows.
If <SecPos[10:2]> = “100 0000 00xx”,
secure positioning is disabled; the
stepper ? motor will be kept in the position
occupied at the moment these events occur.
