27-25
Parameter Data Type Range of Values Default Description
NEG_P_ON BOOL FALSE NEGATIVE PULSE ON
In the manual mode with three-step control,
the output signal QNEG_P can be set at
the
input parameter "negative pulse on." In the
manual mode with two-step control,
QNEG_P is always set inversely to
QPOS_P.
SYN_ON BOOL TRUE SYNCHRONIZATION ON
By setting the input parameter
"synchronization on," it is possible to
synchronize automatically with the block
that updates the input variable INV. This
ensures that a changing input variable is
output as quickly as possible as a pulse.
COM_RST BOOL FALSE COMPLETE RESTART
The block has an initialization routine that is
processed when the COM_RST input is set
CYCLE TIME >= 1ms T#10ms SAMPLING TIME
The time between block calls must be
constant. The "sampling time" input
specifies the time between block calls.
Note
The values of the input parameters are not limited in the block. There is no
parameter check.
Output Parameters
Parameter Data Type Values Default Description
QPOS_P BOOL FALSE OUTPUT POSITIVE PULSE
The output parameter "output positive pulse" is set when
a pulse is to be output. In three-step control, this is
always the positive pulse. In two-step control, QNEG_P is
always set inversely to QPOS_P.
QNEG_P BOOL FALSE OUTPUT NEGATIVE PULSE
The output parameter "output negative pulse" is set when
a pulse is to be output. In three-step control, this is
always the negative pulse. In two-step control, QNEG_P
is always set inversely to QPOS_P.
