Index value + Function Description
0 Starting frequency (SF)
1 Gap frequency (GF)
2 Target frequency (TF)
3
Lower byte of total output pulse
numbers amount
4
Higher byte of total output pulse
numbers amount
5
Lower byte of total accel/decel interval
output pulse numbers
6

3. Instruction of Functions:
It is not necessary to use commands. After user complete the
parameter list, set up M1115 to start. (This step must be executed in
RUN mode). The function only can use Y0 output and the timing chart
is shown as follow:
A
PAP
SF
TF
GP
GF
frequency
AP are the numbers of
accel/decel pulse
pulse numbers
accel/decel steps=(TF-SF) / GF
output pulse numbers of each step(GP)
=AP / accel/decel steps
4. Note:
These additional functions will not be executed if anyone of the limit
conditions below is not compatible:
1. Starting frequency (SF) < Target frequency (TF)
2. Target frequency (TF) < Target frequency (TF) – Starting frequency
(SF)
3. Total pulse numbers amount > numbers of accel/decel pulse x 2
4. During RUN execution, if there is a PLSY command to assign Y0
output, please first start the command of Y0 output and keep on
executing and not execute the other.
5. Minimum of starting and target frequency: 25Hz
Maximum of starting and target frequency: 10KHz
6. Numbers of of accel/decel pulse > accel/decel steps
When M1115 goes from ON to OFF, M1119 will be reset and M1116,
M1117 and M1118 will has no change. When PLC goes from STOP to
RUN, M1115 to M1119 will be reset to OFF and when PLC goes from
RUN to STOP, M1115 to M1119 will also be reset to OFF. D1104 will be
reset to 0 only when it goes OFF to ON but in other conditions, D1104
will has no change.
How to count the action time of each interval
For example, if the user set the starting frequency is 1KHz, gap
frequency is 1KHz, target frequency is 5KHz, total pulse numbers
amount is 100 and numbers of accel/decel pulse is 40, then the timing
chart of accel interval will be shown as below:
