HardStop
Table 50.
The HardStop command causes an immediate motor stop with infinite deceleration.
When the motor is in high-impedance state, a HardStop command forces the bridges to exit
from high-impedance state; no motion is performed.
This command can be given anytime and is immediately executed. This command keeps
the BUSY flag low until the motor is stopped.
SoftHiZ
Table 51.
The SoftHiZ command disables the power bridges (high-impedance state) after a
deceleration to zero; the deceleration value used is the one stored in the DEC register (see
Section
When the motor is stopped, a SoftHiZ command forces the bridges to enter high-impedance
state.
This command can be given anytime and is immediately executed. This command keeps
the BUSY flag low until the motor is stopped.
HardHiZ
Table 52.
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 high-
impedance state.
This command can be given anytime and is immediately executed.
This command keeps the BUSY flag low until the motor is stopped.
