Note:
1.
This function should be executed when the following conditions all exist. Once the condition
does not exist, this function will stop executing.
2.
Start frequency must be less than the target frequency.
3.
Gap frequency must be less than the (target frequency – start frequency)
4.
Total number of pulse number must be greater than (accel/decel pulse number *2)
5.
Start frequency and target frequency: the minimum is 25Hz and the maximum is 10KHz.
6.
Accel/decel pulse number must be more than accel/decel step number
7.
When M1115 is from ON to OFF, M1119 will be cleared and M1116, M1117 and M1118 are
unchanged. When the ELC is switched from STOP
Æ
RUN or from RUN
Æ
STOP,
M1115~M1119 will be cleared to OFF. And D1104 will be cleared to 0 only when it is from
OFF
Æ
ON.
8.
If the function “acceleration/deceleration pulse output” and instruction PLSY Y0 output exist at
the same time, it will execute the one action that starts the Y0 output first.
How to calculate action time of each section
1.
If start frequency is set to 1KHz, gap frequency is set to 1KHz, target frequency is set to 5KHz,
total pulse number is 100 and accel/decel pulse number is 40, timing chart of accel/decel area
is in the following.
