706 / P947.6 Software limit switch, start
Cause The actual position lies outside the range defined by the software limit
switch.
When traversing to a software limit switch, the motor is always stopped.
SW 1.6 and higher:
This fault is also signalled if the traversing range limits of the axis
(+/– 200000mm or degrees or inches) are reached. In this case, the Addi-
tional information 910 (P954.10) is output.
SW 2.0 and higher:
This error is also output when the corresponding hardware limit switch
(start) has been overrun.
In this case, additional information 911 (P954.11) is output.
Note:
The fault can be changed-over to a warning using P30 (fault suppression).
Remedy Move away in the opposite direction.
Check P6 (software limit switch, start).
Acknowledgement Remove cause, set STW.7 = 1/0 and STW.0 = 0/1
Stop response Braking with maximum acceleration (P22)
707 / P947.7 Software limit switch, end
Cause The actual position lies outside the range defined by the software limit
switch.
When traversing to a software limit switch, the motor is always stopped.
SW 1.6 and higher:
This fault is also signalled if the traversing range limits of the axis
(+/– 200000mm or degrees or inches) are reached. In this case, the Ad-
ditional information 910 (P954.10) is output.
SW 2.0 and higher:
This error is also output when the corresponding hardware limit switch
(end) has been overrun.
In this case, additional information 911 (P954.11) is output.
Note:
The fault can be changed-over to a warning using P30 (fault suppres-
sion).
Remedy Move away in the opposite direction.
Check P7 (software limit switch, end).
Acknowledgement Remove cause, set STW.7 = 1/0 and STW.0 = 0/1
Stop response Braking with maximum acceleration (P22)
