Note!
The bits of the status word are not buffered. They represent the current
controller status.
Inadditiontothe controllerstatus, variousevents aredisplayed inthe statusword, i.e.each
bit is assigned with a certain event (e.g. following error).
Depending on the operating mode (modes_of_operation), the meaning of some bits
differs:
Operating
mode
Bit 10 Bit 12 Bit 13 Bit 14 Bit 15
Profile
position
mode
z target_reached
This bit is set when
the current target
position is reached
and the current
position (index
position_actual_
value) is within the
selected position
window (position_
window).
The bit is also set,
when the drive comes
to standstill when the
stop bit is set.
It is deleted when a
new target is
selected.
z set_point_acknow
ledge
This bit is set when
the controller has
identified the set bit
4 in the control word
(new_set_point).
It is deleted when bit
4 is reset to zero in
the control word
(new_set_point).
z following_error
This bit is set when
the current actual
position (index
position_actual_
value) differs from
the setpoint position
(index position_
demand_value) and
the difference is not
within the selected
tolerance margin
(indices following_
error_window,
following_error_
time_out).
z waiting_for_sync
This bit is set when
the drive waits for a
synchronisation edge.
When this bit is not
set, the drive is
controlled
independently of a
synchronisation edge.
z deceleration_
active
This bit is set when
the axis decelerates.
When this bit is not
set, the drive is not
decelerated.
Profile
velocity
mode
z target_reached
This bit is set when
the current actual
speed of the drive has
reached the speed
setpoint.
z speed_0
This bit is set when
the current speed is
zero.
z max_slippage_
error
This bit is set when
the maximum
following error is
reached.
z waiting_for_sync
This bit is set when
the drive waits for a
synchronisation edge.
When this bit is not
set, the drive is
controlled
independently of a
synchronisation edge.
z deceleration_
active
This bit is set when
the axis decelerates.
When this bit is not
set, the drive is not
decelerated.
Profile
torque
mode
z
target_reached
This bit is set when
the current actual
torque of the drive
has reached the
torque setpoint.
z
speed_0
This bit is set when
the current speed is
zero.
z
reserved
This bit is not
assigned and must
not be evaluated.
z
waiting_for_sync
This bit is set when
the drive waits for a
synchronisation edge.
When this bit is not
set, the drive is
controlled
independently of a
synchronisation edge.
z
deceleration_
active
This bit is set when
the axis decelerates.
When this bit is not
set, the drive is not
decelerated.

z
reserved
z
homing_attained
This bit is set when
homing has been
completed
successfully.

This bit is set when
an error has occurred
during homing.
