Program

Number of tasks

Motion task: 8 tasks max.

Parallel branching in task Motion task: 8 branches max.

Number of programs

256 programs max. /unit

The program Nos. used for programs are from 0000 to 0999.

Program numbers

0000 to 0499: Main programs for motion tasks

0500 to 0999: Sub-programs for motion tasks

Program capacity

2 Mbytes

8000 blocks max. /unit by motion program conversion.

Number of blocks

800 blocks/program

Position data capacity

10240 points/unit

Sub-program nesting

5 levels max.

Start

Starts program operation from program (of another task)

Start mode

Motion task: Initial, continue, next

Deceleration stop

Motion task: Executes deceleration stop regardless of block

Block stop

Motion task: Executes deceleration stop at the end of the block currently being executed.

Single-block mode

Motion task: the program is executed one block at a time.

Breakpoints (supported

for unit version 3.0 and

later.)

Breakpoints can be set for any block using the Support Tool. When a breakpoint is set for a block, program exe-

cution will stop after that block has been executed.

Saving program

data

MC Unit

Flash memory backup

Zones (supported for unit version 3.0 and

later.)

The zone bit turns ON when any variable (including feedback present position, feedback speed, etc.) is within

the set range, and OFF when outside of the set range.

A maximum of 32 zones can be set.

Data tracing (supported for unit version 3.0

and later.)

A maximum of two groups can be simultaneously traced, with 1 to 16 data items in each group.

Note: The items that can be traced are bits and data. These are each handled as a single item.

The number of data samples that can be collected is 2,048 samples when 16 items are set for tracing to 32,768

when only 1 item is set for tracing.

Self-diagnostic function

Watchdog, FLASH-ROM check, RAM check, etc.

Error detection function

Deceleration stop input, unit number error, CPU Unit error, software limit over errors, etc.

Error log function

The error log is to be read from the CPU Unit by means of the IORD instructions as needed.

Alarm reset

Alarm reset

Program and CAM data read protection (sup-

ported for unit version 3.1 and later)

Third party access to program and CAM data can be restricted using the CX-Motion-MCH version 2.1 read pro-

tection function (password setting).
