Motion Control Processing Time

The motion control processing time depends on the number of servo axes and virtual servo axes that

are used.

For the number of servo and virtual servo axes, read the motion control processing time from the follow-

ing graph.

Common Processing Time

The common processing time is the following values by the total time for system overhead, system

common processing 1, and system common processing 2. The common processing time depends on

Total number of bytes are given below for pDout, pDin and pDinout.

pDout = 2 + 23 × 4 + 62 = 156 [byte]

pDin = 3 + 1 + 26 × 4 + 88 = 196 [byte]

pDinout = 3 + 2 + 26 × 4 + 88 = 197 [byte]

From these values, the I/O refresh time is calculated by the following formula.

I/O refresh processing time

= EtherCAT slave processing time

= 0.0008 × pDout + 0.0028 × pDin + 0.082 × pDinout + (1.24 × Snum + 0.01 × Clen)

= 0.0008 × 156 + 0.0028 × 196 + 0.082 × 197 + (1.24 × 7 + 0.01 × 10)

= 0.1248 + 0.5488 + 16.154 + (8.68 + 0.1)

≈ 26 [μs]

z User Program Execution Time

The graphs show the following values.

• Standard instruction configuration

From the graph of the execution time for standard ladder diagram instructions, the user program

execution time of 5,000 instructions for the NY52- is 16.5 μs.

• Arithmetic instructions for LREAL data

From the graph of the execution time for ladder diagram arithmetic and trigonometric instructions

for LREAL data, the user program execution time of 200 instructions for the NY52- is

2.5 μs.

A-21

Appendices

• Trigonometric instructions for LREAL data

From the graph of the execution time for ladder diagram arithmetic and trigonometric instructions

for LREAL data, the user program execution time of 100 instructions for the NY52- is 10

μs.

Therefore, the user program execution time is the total of the above values, which is given by the fol-

lowing formula.

User program execution time = 16.5 + 2.5 + 10

= 29 [μs]

z Motion Control Processing Time

From the graph of the execution time for motion control processing, the execution time of the motion

control processing for four axes for the NY52- is read as 7 μs.

z Common Processing Time

Because the task is the primary periodic task, the common processing time for the NY52-

is 258 μs.

Therefore, the average real processing time of the task is given by the following formula.

Average real processing time of task = I/O refresh processing time + User program execution time

+ Motion control processing time + Common processing time

= 26 + 29 + 7 + 258

= 320 [μs]

Setting the Task Period

The task period is set based on the average real processing time of the task that is calculated as above.

The task is the primary periodic task.

The value of the task period must be larger than the average real processing time of the task that you

calculated. More specifically, you should allow sufficient margin and set the task period value to at least

1.1 times as large as the average real processing time of the task.

Task period ≥ Average real processing time of task × 1.1

Because the average real processing time of the task that is calculated above is 320 μs, the task period

is set to 500 μs, which is larger than 1.1 times the average time.

The task execution times in the physical Controller depends on the logic operations that are performed

in the user program, the presence of communications commands and data links, on whether data trac-

ing is performed, the load on Windows, the connection of Industrial Monitors, the usage of PCIe cards,

and on other factors. The task execution time for a periodic task depends on whether it is interrupted for

the execution of tasks with higher execution priorities.

Use the physical Controller and verify the task execution time with the Task Execution Time Monitor.

System-defined Variables

System-defined variables are assigned specific functions by the system. They are registered in the

global variable table, or the local variable table for each POU, in advance.

These variables cannot be changed. Some of the variables start with an underbar and some start with

”P_”.

Some of the system-defined variables are read-only and some are read/write.

You read and write the variables with the user program, with communications from external devices,

with the Sysmac Studio, or with an NS/NA-series PT.

Basically, system-defined variables are classified according to the function modules. The variables start

with the following category names.

Precautions for Correct Use

There are system-defined variables that are not supported or differ in specifications such as the

number of arrays. Refer to A-4 Specifications for Individual System-defined Variables for details on the

specifications for individual system-defined variables.

Hierarchical Relationship of System-defined Variables Related to EtherNet/IP Errors in the

NY-series Controller

The system-defined variables that are related to EtherNet/IP errors have the following hierarchical

relationship. For example, if the value of any of the _EIP1_PortErr, _EIPIn1_PortErr, _EIP_CipErr,

and _EIP_TcpAppErr variables in the second level is TRUE, then the _EIP_ErrSta variable in the

first level also changes to TRUE. Therefore, you can check the values of system-defined variables

in a higher level to see if an error has occurred for a variable in a lower level.
