User manual - COUNTER
“rEF”
- reference point (offset) of relay threshold. Available values:
“Std”
- use 0 value as reference point (offset)
“rELPr1”
- use threshold of the relay
R1
as reference point (offset)
This parameter is not available for relay R1. If
rELPr1
option is set, then relay
threshold is modified by relay
R1
threshold (
“SEtP 1”
value). It means that state of
relay (different than
R1
) will be changed earlier or later in reference to value of the
relay
R1
threshold.
7.3.2.
“ Funct
” parameter
This parameter allows to define operation mode of the counter, and can be set to one of
the values:
”A + B”
- add mode; addition of pulses from both counting inputs (A and B) to current
counter result.
”A - B”
- subtract mode; Pulses from input A are added to, and pulses from input B
ad subtracted from counter result.
”qUAd-1”
- quadrature mode 1; This option enables cooperation of inputs A and B as
quadrature input with normal resolution, it means that counter is incremented
(decremented) by 1 every single quadrature cycle on inputs A and B
”qUAd-4”
- quadrature mode 4; This option enables cooperation of inputs A and B as
quadrature input with increased resolution, it means that counter is incremented
(decremented) by 1 every one-fourth of single quadrature cycle on inputs A and B.
7.3.3.
“Pr inP” parameter
This parameter defines the function of the programmable input
{ C }
. When
active state
is delivered to programmable input, it causes of the activating of particular function. This
parameter can be set to one of the values:
”diSAbL”
- programmable input is not active,
”dirEct”
- active signal on the programmable input changes counting function
(counting direction) from
„A-B
”
to
„B-A
”
,
from
„A+B
”
to
„-(A+B)
”.
”inhibi”
- programmable input stops the counting,
7.3.4.
“rESEt”
parameter
This parameter determines the counter zeroing (reset) sources, and can be set to one of
the values:
”ALL”
- this option enables both manual (using
[RESET
] button) and electronic reset.
”EL”
- this option enables external reset input
{ D }
. If an active signal is delivered to the
input
{ D }
the counter is zeroed, and the result stays zero ( or equal to offset) as
