Multiple Axes Simultaneous Start - Mitsubishi Electric MELSEC iQ-R Series User Manual

Multiple axes simultaneous start

The "multiple axes simultaneous start" starts outputting the command to the specified simultaneous starting axis at the same
timing as the started axis. The maximum of four axes can be started simultaneously.
Control details
The multiple axes simultaneous start control is carried out by setting the simultaneous start setting data to the multiple axes
simultaneous start control buffer memory of the axis control data, "9004" to "[Cd.3] Positioning start No." of the start axis, and
then turning ON the positioning start signal.
Set the number of axes to be started simultaneously and axis No. in "[Cd.43] Simultaneous starting axis", and the start data
No. of simultaneous starting axis (positioning data No. to be started simultaneously for each axis) in "[Cd.30] Simultaneous
starting own axis start data No." and "[Cd.31] Simultaneous starting axis start data No.1" to "[Cd.33] Simultaneous starting
axis start data No.3".
Restriction
• The error "Error before simultaneous start" (error code: 1A90H, 1A91H) will occur and all simultaneous starting axes will not
start if the simultaneous starting axis start data No. in the axis control data of the started axis is not set, or is set outside the
setting range.
• The error "Error before simultaneous start" (error code: 1A90H, 1A91H) will occur and all simultaneous starting axes will not
start if either of the simultaneous starting axes is BUSY.
• The error "Error before simultaneous start" (error code: 1A90H, 1A91H) will occur and all simultaneous starting axes will not
start if an error occurs during the analysis on the positioning data of the simultaneous starting axis.
• No error or warning will occur if only the start axis is the simultaneous starting axis.
• This function cannot be used with the sub function Page 270 Pre-reading start function.
Procedure
The procedure for multiple axes simultaneous start control is shown below.
1.
Set the following axis control data.
• [Cd.43] Simultaneous starting axis
• [Cd.30] Simultaneous starting own axis start data No.
• [Cd.31] Simultaneous starting axis start data No.1
• [Cd.32] Simultaneous starting axis start data No.2
• [Cd.33] Simultaneous starting axis start data No.3
2.
Write "9004" in "[Cd. 3] Positioning start No.".
3.
Turn ON the positioning start signal to be started.
Setting method
The following shows the setting of the data used to execute the multiple axes simultaneous start control with positioning start
signals (The axis control data on the start axis is set).
