Bit 12
: incorrect target value
This bit is set:
- when a transferred target value lies outside of the limit switches; also
caused, for instance, because of the actual value of the reference value
(SDO #2004)
- when a transferred target value lies inside of the limit switches; but because
of a necessary loop run the specified interval would be left
This bit is reset:
- with each new run command
Bit 13:
voltage control is valid
The behaviour of this bit is depending of the acknowledgement bit (bit 14) in the
control word.
a) The acknowledgment bit is not set (low)
Failure status is latched, if the positioning system is moving or a run
command is transmitted, otherwise the status of the voltage control signal
is shown
A latched failure is reset, if a new run command is transmitted (while the
voltage control signal is valid / high) or the acknowledgement bit is
toggled (low
high
low)
“voltage control bit” is set:
- If the voltage control is valid (no voltage failure) and no former failure has
been latched
“voltage control bit” is reset:
- If there is a failure in the voltage control
b) The acknowledgment bit is set (high)
The status of the voltage control is always shown directly.
“voltage control bit” is set:
- If there is no failure in the voltage control
“voltage control bit” is reset:
- If there is an failure in the voltage control
Bit 14 / 15
: positive / negative range limit
This bit is set:
- if the limit value is reached during a manual run (but not if reached during a
positioning run)
- if a limit value is modified such that the current position lies beyond the limit
- if, while on standstill, by means of an external force the drive is moved to a
position which is outside the area which is defined by the range limits
This bit is reset:
- as soon as the actual position is again inside the range limits (Exception:
After the end of a manual run the drive is located still at the range limit within
the positioning window and no new run command was issued yet.)
2.9.5 Detailed description of control bits
Bit 0
:
manual run to larger values
Bit 1
:
manual run to smaller values
Bit 2
:
transfer target value
When transferring target values with the help of PDOs, the target value in the
PDO will be taken over if this bit is set. A positioning run which starts
simultaneously or later uses this target value as new target position. If
together with taking over the target value the positioning run shall start
immediately, bit 4 (‘release’) has to be set additionally.
