SIMOVERT MASTERDRIVES
If the deviation is within the innermost window (window 1), the homing
point is not set. Neither is the homing point set if the deviation is outside
the outermost window (window 2).
The output B0892 error homing point proximity switch outside window 2
is activated.
This output signal stays on until a homing point mark is next evaluated.
Both windows can be disabled individually by assigning them values of
0.
Fault and warning messages
The free BASIC POSITIONER blocks do not generate any fault or
warning messages. The positioning software does not respond to
messages caused by incorrect parameters either (e.g. violation of
limit values).
