8 APPLICATION INSTRUCTION
8.16 Ramp Signal Instruction
Processing details
• When the start value (s1) and the end value (s2) have been specified and the command input is set to ON, the value
obtained by adding a value divided equally by "n" times to (s1) in the next operation cycle is stored to (d). 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 (d)+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 current value stored in (d) is held,
and the number of scans stored in (d)+1 is cleared.) When the command input is set to ON again, (d) is cleared, and the
operation is started from (s1).
• After transfer is completed, the instruction execution complete flag SM8029 turns ON, and the (d) value is returned to the
(s1) value.
• When the operation result is acquired at a constant time interval (constant scan mode), write a prescribed scan time (which
is longer than the actual scan time) to SD8039 and set SM8039 to ON. For example, when "20 ms" is written to SD8039
and "n" is set to 100, the (d) value will change from (s1) to (s2) in 2 seconds.
• The value used in the constant scan mode can be set in the parameter setting of an engineering tool (constant scan
execution interval setting of CPU parameter).
For details on the constant scan, refer to
MELSEC iQ-F FX5 User's Manual (Application).
For details on the engineering tool, refer to
GX Works3 Operating Manual.
