Performance Characteristics Appendix A
Although the average data saving time is 300 ms, it may be as long as 33 s in some cases. If it is longer than
33 s, a flash memory error (error code 9300) will be generated, and the data saving operation will be inter-
rupted.
Effect on the Programmable Controller Cycle Time
The PLC’s cycle time increases if Units are added, or if the IOWR or IORD instructions are executed. The times
by which the cycle time will increase are shown in the following table.
Minimum Operation Time
The minimum operation time for the Position Control Unit is 10 ms. With memory operation, when a sequence
with a “continuous” completion code is executed and the positioning time for that sequence is shortened
according to the amount of movement and the target speed, the operation time required for the continuous
completion cannot be assured and positioning will be executed as if the completion code were “automatic.”
When using a sequence with a “continuous” completion code, be sure to adjust the target speed and target
position so that the operation time will be equal to or greater than the minimum operation time.
