Starting/Ending For Synchronous Control - Mitsubishi Electric MELSEC iQ-R Series User Manual

Precautions
• Mechanical elements such as limit switches are considered as already installed.
• Parameter settings for positioning control apply for all axes with the Simple Motion module.
• Be sure to execute the home position return when the home position return request flag is ON.

Starting/ending for synchronous control

Set the advanced synchronous control parameters for each output axis to start synchronous control.
The status changes to synchronous control after the advanced synchronous control parameters are analyzed at the start of
synchronous control, and the output axes synchronize with input axis operations.

[Cd.380] • Synchronous control begins if the target axis bit
Synchronous is turned ON.
control start • Synchronous control ends if the bit is turned
OFF during synchronous control.
Fetch cycle: Operation cycle
*1 When the synchronous control analysis mode is executed simultaneously or the synchronous control analysis mode and the
synchronous control start are executed simultaneously for multiple axes, perform the setting for the synchronous control start in batches
for each word. If the axes are set continuously in bits, the synchronous control analysis mode and the synchronous control start may not
operate depending on the timing.
*2 The range from axis 1 to 2 is valid in the 2-axis module, from axis 1 to 4 is valid in the 4-axis module, from axis 1 to 8 is valid in the 8-axis
module, from axis 1 to 16 is valid in the 16-axis module, and from axis 1 to 32 is valid in the 32-axis module.
