6.4 Pulse Output Function
6 - 41
Pulse output control instruction (F0)
This instruction is used for resetting the built-in high-speed counter, stopping the pulse
outputs, and setting and resetting the home position proximity input.
Specify this
F0 (MV) instruction together with the special data register DT90052.
Once this instruction is executed, the settings will remain until this instruction is
executed again.
Example 1: Enable the home position proximity input during home return
operations and begin deceleration.
In the program, the home position proximity input is enabled in
step
1
and 0 is entered just after that in step
2
to perform the
preset operations.

Elapsed value write and read instruction (F1)
This instruction is used to read the pulse number counted by the built-in high-speed
counter.
Specify this F1 (DMV) instruction together with the special data register DT90044.
The elapsed value is stored as 32-bit data in the combined area of special data
registers DT90044 and DT90045.
Use only this F1 (DMV) instruction to set the elapsed value.
Example 1: Writing the elasped value
X7
DF F1 DMV, K3000, DT90044
Set the initial value of K3000 in the
high-speed counter.

Example 2: Reading the elapsed value
X8
DF F1 DMV, DT90044, DT100
Reads the elapsed value of the
high-speed counter to DT100 and
DT101.
