Table 8.2-19 Error code in Gx_XIST2
The following boundary conditions and rules exist:
1. The function "Referencing only with rough pulse" is not supported in
the standard interconnections. For this measurement via the
measured value memory of the basic unit must be used. If the
measured value memory is to be used both for referencing and for
measurement, corresponding interconnections in the basis unit via
free blocks must be used.
2. The function "Referencing only with zero mark" must be ensured via
corresponding interconnections in the basic unit using B931 "Trigger
rough pulse motor encoder“.
In this a rough pulse is produced as soon as the release of the
reference point recording is switched to enabled. The next zero pulse
is then recognized.
1. The functions "Referencing“ and "Measured value memory" is only
supported by the SBP (pulse encoder board) . For this the measured
value memory should be used via direct input to the SBP (see
function diagram 335).
2. The rough pulse in the external encoder is only evaluated directly on
the encoder board (see function diagram 255).
3. The "Referencing" function with zero mark only is not supported.
