Reference position reached/outside reference posi-
60 – x ZSW1.10
x – Meldw.14
This output signal is used to display, in the positioning mode (ZSW1.10), whether the axis has reached
the end of the traversing block (position reference value = target position) and the position actual value
lies within the positioning window (P0321).
In the n–set mode, MeldW.14 indicates that the reference position has been reached when positioning
the spindle
1 signal Reference position reached
The axis/spindle is at the end of a traversing task and the position monitoring time
(P0320) has expired within the positioning window (P0321).
0 signal Outside the reference position
The axis/spindle is outside the positioning window.
Note:
The signal is not set when the axis stops, if
– the axis is in the closed–loop speed controlled jogging mode
– an ongoing traversing block is interrupted or canceled using ”intermediate stop” or ”stop” which
means that the target position has not been reached
The signal remains set, until
– a new traversing block is started
– the axis is traversed in the jogging mode
– a reference point approach is started
– a fault (alarm) occurs (e.g. one of the monitoring windows P0318, P0321 or P0326) has been ex-
ceeded
The signal remains set if a traversing block is re–started and there is no difference between the target
position and the previous position.
Reference point set/no reference point set 61 – x ZSW1.11
The output signal indicates whether an axis is referenced.
When referencing, the incremental measuring system of the axis is synchronized with the drive.
1 signal Reference point set
The axis has a valid reference point.
0 signal Reference point set
The axis does not have a valid reference point.
Note:
The following functions are not effective for an axis which is not referenced:
Software limit switch
Backlash compensation
Start the traversing blocks
