Counting direction
This item specifies the direction in which counting is to be performed.
Phase A DOWN
/counterclockwise
Phase A UP
/clockwise
Clear Signal Input Logic
Selecting clear signal (phase Z) input logic
Setting the Clear Signal Operation
This item specifies the operation of clear signal (phase Z) input
- Clear signal input disabled
Z-phase input
Counter
- Enabled only for one-time input of the next clear signal
Z-phase input
Counter
- Enabled for all clear signal input operations
Z-phase input
Counter
Figure 5.8.
Note!
When not using the clear signal (phase Z) option, choose the " C lear signal input
disabled" setting.
Preset count values
Entering the value allows the counter value to be set as a preset value.
The function works only when the value is set in this area only.
