– The clamping torque remains, if ...
subsequently, e.g. blocks are processed with the commands
WAIT, GOTO, SET_O or RESET_O
There is no subsequent block, i.e. the traversing program has
been completed
– the position can be read in P0002 (actual traversing block – posi-
tion)
If, for a traversing block, the axis moves to the brake initiation point
with the FIXED ENDSTOP command, without detecting the status ”fi-
xed endstop reached”, then the following behavior applies, dependent
on P0113.0:
Table 6-68
Behavior, if the fixed endstop is not reached
If
Then the following is valid:
P0113.0 = 0
(Standard)
Fault 145 is signaled
The torque limiting is automatically disabled. The axis is braked
and comes to a standstill in front of the programmed target posi-
tion. The deviation from the reference position depends on:
Positioning velocity
Acceleration
Deceleration
P0113.0 = 1
A block change is made
The torque limiting is automatically disabled. The block change
enable is realized as programmed in the block.
The ”travel to fixed endstop” function is interrupted, and if warning 889
is present it is acknowledged, if one of the following occurs:
The next block is processed with the POSITIONING command
the jogging mode is selected if previously interrupted
––> with the input signal ”reject operating condition/traversing task”
The controller enable is withdrawn (––> fault 147)
Pulse enable is withdrawn (––> fault 147)
The following applies for a traversing block with the FIXED ENDSTOP
command:
Interrupt and continue
––> using the ”operating condition/intermediate stop” input signal
Exit
––> using the ”operating condition/reject traversing task” input signal
In all of these cases, the drive is correspondingly braked.
Interruption at the fixed endstop:
The drive remains at the fixed endstop, and can be moved away from it
either in the jog mode, or by starting a new traversing block.
What happens if
the fixed endstop
is not reached?
Canceling the
”travel to fixed
endstop” function
Interrupting or
exiting the ”travel
to fixed endstop”
function
