Setting the Counter with DI Set and Zero Mark
If you parameterize setting of a counter with the zero mark of the encoder, the counter will be
set with the rising edge of the zero mark.
Setting is performed only if DI Set is additionally set at the time of the rising pulse edge of
the zero mark.
You can determine the behavior of the FM 350-1 in the case of a rising edge of the zero
mark via the ENSET_UP and ENSET_DN variables in the DB of the FC CNT_CTL1 and via
parameterization.
Table 7- 27 Setting the Counter with DI Set and Zero Mark
Input parameters
Behavior of the FM 350-1
ENSET_UP set
The counter is only set in the case of up counting
ENSET_DN set
The counter is only set in the case of down counting
ENSET_UP and
ENSET_DN set
The counter is set in the case of up and down counting
Parameter assignment
"single setting of counter"
The counter is set only at the first rising edge of the zero mark.
If the counter is to be set again, you must first set ENSET_UP or
ENSET_DN again (edge evaluation). The counter is then set again with
the next rising edge of the zero mark.
Parameter assignment
"multiple setting of
counter"
As long as ENSET_UP and/or ENSET_DN are set, the counter will be set
with each rising edge of the zero mark.
Note
You must always set one of the two variables ENSET_UP and/or ENSET_DN so that the
counter can be set with the zero mark.
