S: This function is supported only in FX3G/FX3GC/FX3U/FX3UC PLCs.
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.
If the command input is set to OFF in the middle of operation, execution is paused. (The present data value stored
in is held, and the number of scans stored in +1 is cleared.) When the command input is set to ON
again, is cleared, and the operation is started from .
Operand type Description Data type
Device number storing the initial value of ramp 16-bit binary
Device number storing the target value of ramp 16-bit binary
Device number storing the current value of ramp 16-bit binary
n Ramp transfer time (scan) [1 to 32, 767] 16-bit binary
