FNC 67 – RAMP / Ramp Variable Value
Outline
This instruction obtains the data which changes between the start value (initial value) and the end value
(target value) in specified "n" times.
1. Instruction format
2. Set data
3. Applicable devices
Explanation of function and operation
1. 16-bit operation (RAMP)
When the start value
and the end value
have been specified and the command input is set to
ON, the value obtained by adding a value divided equally by "n" times to
in every operation cycle is
stored to
.
By combining this instruction and an analog output, the cushion start/stop command can be output.
• The number of scans ("0" to "n") is stored in
+1.
• The time from start to the end value is the operation cycle multiplied by "n" times.
