6.4.2.3 Counter Channel 1 CountDirection (3001: 04h)
The parameter can be used for specifying the direction of counting when the “single pulse input” mode is set
as the pulse input mode for counter channel 1.

Default

Counter channel 1
CountDirection
SINT RW YES 0
The parameter value is 0 by default, which means counting up. If the parameter is set to 1 or other value, it
means counting down.
If you modify the parameter value during counter channel 1 counting, the modification will not be effective
right away until the Counter channel 1 command parameter changes from 0 to 1.
The function of the parameter is invalid if the set input mode is “pulse+ direction” or “phase A + phase B” for
counter channel 1.
6.4.2.4 Counter Channel 1 AB-Phase FrequencyMode (3001: 05h)
The parameter is available to set the frequency multiplication when “phase A + phase B” is set as the pulse
input mode for counter channel 1.

Description
1
Phase A + phase B: 1x
2
Phase A + phase B: 2x
4
Phase A + phase B: 4x
If the parameter is set to other value except 1, 2 and 4, it is 4x frequency multiplication by default.
6.4.2.5 Counter Channel 1 Present CounterValue (3001: 06h)
The parameter is the current counter value for counter channel 1.

Present CounterValue
LREAL RW YES 0
The parameter displays the current pulse number for counter channel 1 in real time. The range of counting is
the valid range of the data type LREAL, i.e. -1.79769313486231e+308 ~ -2.22507385850721e-308，0，
+2.22507385850721e−308 ~ +1.79769313486231e+308.
6.4.2.6 Counter Channel 1 TriggerMode (3001: 07h)
Through setting the value for the parameter, the counting can be triggered by the rising edge or falling edge of
input pulses at X0.0 when “pulse + direction” is the pulse input mode for counter channel 1.
