At the designation of maximum counter frequency, two types of indication
are distinguished:
• Maximum pulse frequency
The maximum pulse frequency is the maximum frequency the adjacent
signal may have, i.e. the maximum frequency at witch the pulses arrive
at the module. At this module the maximum pulse frequency depends on
the counter-signal-evaluation chosen.
Signal evaluation Maximum pulse frequency
single 30kHz
duplicate 15kHz
quaduplicate 7.5kHz
• Maximum counter frequency
The maximum counter frequency is the frequency at witch can be
internally counted to the maximum.
At employment of all 3 counters, every counter may use a frequency of
max. 30kHz. If you employ only 1 counter channel, the counter supports
a max. frequency of 100kHz.
The parameterization allows you to define a main counting direction for
every counter.
If you choose "none", the complete counting range is available:
Valid value range
Lower count limit - 2 147 483 648 (-2
31
)
Upper count limit + 2 147 483 647 (2
31
-1)
Main counting direction forward
Upper restriction of the count range. The counter counts 0 res. load value in
positive direction until the parameterized end value –1 and jumps then back
to the load value with the next following encoder pulse.
Main counting direction backwards
Lower restriction of the count range. The counter counts from the
parameterized start- res. load value in negative direction to the
parameterized end value +1 and jumps then back to the start value with the
next following encoder pulse.
Abort count process
The count process starts after closing and restart of the gate beginning with
the load value.
Interrupt count process
The count process continuous after closing and restart of the gate
beginning with the last recent counter value.
