status_sg
1: Signals an active stallGuard2 input from the coolStep driver or
from the dcStep unit, if enabled.
Hint: When polling this flag, stall events may be missed – activate
sg_stop to be sure not to miss the stall event.
1: Signals that the automatic ramp required moving back in the
opposite direction, e.g. due to on-the-fly parameter change
(Write ‘1’ to clear)

t_zerowait_
active
1: Signals, that TZEROWAIT is active after a motor stop. During this
time, the motor is in standstill.

vzero
1: Signals, that the actual velocity is 0.
1: Signals, that the target position is reached.
This flag becomes set while XACTUAL and XTARGET match.
1: Signals, that the target velocity is reached.
This flag becomes set while VACTUAL and VMAX match.
1: Signals, that the target position has been reached
(position_reached becoming active).

event_stop_
sg
1: Signals an active StallGuard2 stop event.
Reading the register will clear the stall condition and the motor may
re-start motion, unless the motion controller has been stopped.
(Write ‘1’ to clear flag and interrupt condition)
This bit is ORed to the interrupt output signal.
R
event_stop_r
1: Signals an active stop right condition due to stop switch.
The stop condition and the interrupt condition can be removed by
setting RAMP_MODE to hold mode or by commanding a move to the
opposite direction. In soft_stop mode, the condition will remain
active until the motor has stopped motion into the direction of the
stop switch. Disabling the stop switch or the stop function also
clears the flag, but the motor will continue motion.
This bit is ORed to the interrupt output signal.
4
event_stop_l
1: Signals an active stop left condition due to stop switch.
The stop condition and the interrupt condition can be removed by
setting RAMP_MODE to hold mode or by commanding a move to the
opposite direction. In soft_stop mode, the condition will remain
active until the motor has stopped motion into the direction of the
stop switch. Disabling the stop switch or the stop function also
clears the flag, but the motor will continue motion.
This bit is ORed to the interrupt output signal.
