4. SERVO SYSTEM CPU DEVICES

4 − 19

(11) Motion slot module error detection flag (M2047)

........................................................................Signal sent from PCPU to SCPU

This flag indicates whether the status of modules mounted at the base unit

and extension base units is normal or abnormal.

• ON..............Status of mounted module is abnormal

• OFF ........... Status of mounted module is normal

Module information is checked for errors both when the power is switched ON

and after the power has been switched ON.

(a) When M2047 switches ON, the A273UHCPU "ERROR" LED switches ON.

(b) Required processing when an error is detected (axis STOP, servo OFF,

etc.) should be conducted at the sequence program.

0: CPU base

1: Motion extension base 1

2: Motion extension base 2

3: Motion extension base 3

4: Motion extension base 4

"SL00 UNIT ERROR"

I/O slot No. (0 to 7)

Base unit No.

POINT

Positioning control will continue even if an error is detected at a motion slot.

(12) JOG simultaneous START command (M2048)

..........................................................................Signal sent from SCPU to PCPU

(a) When M2048 switches ON, a JOG simultaneous START will occur at the

JOG execution axis (axis-1 to axis-32) designated at the JOG simultaneous

START Axis Area(D710 to D713).

(b) When M2048 switches OFF, the JOG axis motion will decelerate and stop.

(13) All-Axes servo START accept flag (M2049)

..........................................................................Signal sent from PCPU to SCPU

The all-axes servo START flag indicates that servo operation is possible.

• ON................Servo is operative.

• OFF..............Servo is inoperative.
