Abort
––>while ”traversing to fixed endstop”
The drive brakes and maintains this position with a reduced torque
as ”traverse to fixed endstop” is still active The position is monitored
using P0326. Fault 145 is signaled when the tolerance window in
P0326 is exceeded.
If the axis travels by more than the monitoring window, set in P0116:8
when it reaches the ”fixed endstop reached” status, then the ”travel to
fixed endstop” function is canceled as a result of fault 146 (fixed end-
stop, axis outside the monitoring window), and the axis is stopped.
The following applies for the fixed endstop monitoring window:
Set using P0116:8 (fixed endstop monitoring window).
The monitoring window generally applies for a drive, which means,
in order to adapt it for an individual traversing block, P0116:8 must
be correspondingly re–written into before the block starts.
The value in P0116:8 is valid both in the positive as well as the neg-
ative travel directions.
The window setting must be selected, so that a fault is only initiated
if the endstop breaks.
For a hanging axis without mechanical weight equalization, when pro-
gramming the clamping torque and when defining the fixed endstop
monitoring window, it must be taken into consideration as to whether
the electronic weight equalization is set via P1240:8.
The clamping torque, effective for ”travel to fixed endstop” is made up
as follows:
Programmed clamping torque in the traversing block
and
P1240:8 (offset, torque setpoint speed–controlled)
The following applies when programming the clamping torque for a
hanging axis without mechanical weight equalization:
