−77−
hold reset (MHR), an output signal from the PMC, is set to 1
or the MS signal output from the PMC is set to 0.
(2) Mode B
A. Synchronization with marker
When the MS signal output from the PMC is 1 and the
contact of the marker enable (ME) signal input from the
machine is closed, the counter is set to the data in the counter
preset register at the rising edge of the first marker signal.
B. Maker hold
When the MS signal output from the PMC is 1 and the
contact of the marker enable (ME) signal input from the
machine is closed, the MH signal is set to 1 at the rising edge
of the marker signal. The MH signal is reset when the MS
signal output from the PMC is set to 0.
8.2.7 LED indicators
The high speed counter module has the following indicators.
(1) OK indicator
See below Table.
(2) ALM0 and ALM1 indicators
See below Table.
(3) Phase A and B pulses (positive and negative pulses) input signal
indicators (A and B)
The phase A pulse input signal indicator is on when the phase A
pulse input is active.
The phase B pulse input signal indicator is on when the phase B
pulse input is active.
(4) Marker signal indicator (M)
The marker signal indicator is on while the marker signal (MP)
from the pulse generator is active.
(5) Count stop signal indicator (S)
The count stop signal indicator is on when the contact of the count
stop signal input sent from the machine is closed.
(6) Marker enable signal indicator (E)
The marker enable signal indicator is on when the contact of the
marker enable signal input sent from the machine is closed.
(7) Comparison result output indicators (OUT0, OUT1, OUT2,
OUT3, OUT4, OUT5, OUT6, and OUT7)
