1. The minimum frequency of start frequency and target frequency should be equal to or greater
than 200Hz. If it is less than 200Hz, it means finish executing or not to execute.
2. The maximum frequency of start frequency of target frequency is 32,700Hz. It will execute in
32,700Hz as it is greater than 32,700Hz.
3. The interval time range is 1~32,767ms and its unit is ms.
4. The interval frequency range in acceleration segment is 1Hz~32,700Hz and in deceleration
segment is -1~-32,700Hz. If it is set to 0Hz, the executed segment cannot be up to target
frequency, but it will transfer to execute next segment after reaching target number.
5. Target number of segment pulse output should be greater than ((GF*GT/1000)* ((TF-SF)/GF).
Refer to example 1 for detail. Once Target number of segment pulse output isn’t greater than
((GF*GT/1000)* ((TF-SF)/GF), this function cannot be used. The improve method is to add
interval time or add target number of pulse output.
6. If there is Y0 output designated by high-speed instruction in RUN mode, Y0 output
7. Instruction will be started as high priority.
8. After starting to execute M1144, if M1148 outputs without attaining completed function flag
and M1144 is closed, this function will start deceleration function. If designated acceleration
function flag M1154 is OFF, it will reduce 200Hz per 200ms and stop output pulse till output
frequency is less than 200Hz and set M1147 to deceleration flag. But if designated
deceleration flag M1154 is ON, it will be executed by interval time and frequency that defined
by user. And interval time cannot be less than or equal to 0 (if it is less than or equal to 0,
factory setting will be set to 200ms). Interval frequency cannot be greater than or equal to 0
(factory setting will be set to -1KHz when it is equal to 0 and factory setting will be added
negative sign automatically when it is greater than 0.)
9. When M1148 attains completed function flag and M1144 is closed, this function will not start
deceleration function and it will clear M1148 flag. Once M1144 is closed, it will clear M1149
flag.
10. The execution segment of this function will execute by total segment number. The maximum
segment is 10 segments.
11. The acceleration/deceleration of this function will execute by start frequency of the next
segment, i.e. when target frequency of execution segment is less than start frequency of the
next segment, the next segment is acceleration and the target frequency of the next segment
must be greater than start frequency of the next segment. When target frequency of execution
segment is greater than the next segment frequency, the next segment is deceleration;
therefore, target frequency of the next segment must be less than start frequency of the next
segment. If user cannot set it by this way, we cannot ensure that you can get correct output
pulse.
12. When STOP Æ RUN, M1144~M1149 will be cleared to OFF. When RUN Æ STOP, M1144 will
be cleared and M1145~M1149 will not be cleared. D1144 will be cleared to 0 when it is from
OFF
Æ ON and unchanged in other case.
