10.5 Multiple axes simultaneous start control

MELSEC-Q

The "multiple axes simultaneous start control" starts and controls the multiple axes simultaneously by outputting pulses to the axis to be started at the same timing as the start axis.

The maximum of four axes can be started simultaneously.

[1] Control details

The multiple axes simultaneous start control is carried out by setting the simultaneous start an object axis start data No. (positioning data No. to start simultaneously for each axis) to the multiple axes simultaneous start control buffer memory " Cd.30 to Cd.33 Simultaneous starting axis start data No. (1 to

4 axis start data No.)" of the axis control data, and the "9004" to

"Cd.3 positioning start No." of the start axis, and then turning ON the positioning start signal.

[2]Restrictions

(1)An error will occur and all simultaneously started axes will not start (error code: 501) if the simultaneously started axis start data No. is not set to the axis control data on the start axis or set outside the setting range.

(2)An error will occur and all simultaneously started axes will not start (error code: 501) if either of the simultaneously started axes is BUSY.

(3)An error will occur and all simultaneously started axes will not start (error code: 501) if an error occurs during the analysis of the positioning data on the simultaneously started axes.

(4)No error or warning will occur if only the start axis is the simultaneously started axis.

(5)This function cannot be used with the sub function Section 12.7.8 "Pre- reading start function".

[3]Multiple axes simultaneous start control procedure

The procedure for multiple axes simultaneous start control is as follows.

1)Set " Cd. 30 to Cd. 33 Simultaneously started data No.".

2)Write [9004] to " Cd. 3 Positioning start No.".

3)Turn ON the positioning start signal to be started.
