When the motor is in high-impedance state, a HardStop command forces the bridges to exit
from high impedance state; no motion is performed.
SoftHiZ
Table 53.
The SoftHiZ command disables the power bridges (high-impedance state) after a
deceleration to zero; the deceleration value used is the one stored in DEC register (see
paragraph
When the motor is stopped, a SoftHiZ command forces the bridges to enter in high-
impedance state.
HardHiZ
Table 54.
The HardHiZ command immediately disables the power bridges (high-impedance state) and
raises the HiZ flag.
When the motor is stopped, a HardHiZ command forces the bridges to enter in high-
impedance state.
GetStatus
Table 55.
The GetStatus command returns the Status register value.
GetStatus command resets the STATUS register warning flags. The command forces the
system to exit from any error state. The GetStatus command DO NOT reset HiZ flag.
