MotionSuite™ Series Machine Controller Programming Manual Chapter 3: Advanced Programming Methods

3-25

Important Points

(1) The WHILE WEND command can be nested up to 8 levels.

(2) If the repeated program section is created using only commands for which processing

is completed in one scan, an infinite loop is created and a watchdog timer error

(system error) is generated. Therefore, when using the 1-scan command, the EOX

command (1-scan Wait command) must be set.

(3) Commands that cannot be ended by the 1-scan command:

MOV, MOS, MCW/MCC, ZRN, SKP, MVT, EXM, ACC, SCC, PFN, VEL, INP, TIM,

IOW

(4) Commands that can be ended by the 1-scan command:

ABS, IWC, IFP, PLN, IAC, IDC, FMX, POS, PLD, MSEE, END, RET, IF, WHILE,

PFORK, SFORK, and all of the sequence commands.

! Program Example

In the following program example, ten circular arcs (each with a radius of 50) are drawn.

MOV [axis1]0 [axis2]0;

MW0001=1;

INC;

PLN [axis1] [axis2];

WHILE MW0001

10;

MCW [axis1]0 [axis2]0 U50. V50. F8000;

MOV [axis1]50. [axis2]50.;

MW0001=MW0001+1;
