Multiple Axes Simultaneous Start - Mitsubishi Electric MELSEC iQ-FX5 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".
Restrictions
• The error "Error before simultaneous start" (error code: 1990H) will occur and all simultaneously started axes will not start 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.
• The error "Error before simultaneous start" (error code: 1990H) will occur and all simultaneously started axes will not start if
either of the simultaneously started axes is BUSY.
• The error "Error before simultaneous start" (error code: 1990H) will occur and all simultaneously started axes will not start if
an error occurs during the analysis of the positioning data on the simultaneously started axes.
• No error or warning will occur if only the start axis is the simultaneously started axis.
• This function cannot be used with the sub function Page 252 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.
