Chapter 4 Synchronous Control Startup - Mitsubishi Electric MELSEC iQ-R Series Quick Start Manual

SYNCHRONOUS CONTROL STARTUP
This chapter describes synchronous control, mainly about the synchronous control parameter, positioning data for
synchronous control, and operation check for synchronous control.
Axis 1 operation is the same as that described in Chapter 2.
Refer to Chapter 2 to 3 for details of the parameters and servo parameters.
[Flying Cutter]
Without stopping the conveyor axis (Axis 2), cutter axis (Axis 1) synchronizes to the movement of the conveyor belt and cuts
the work piece evenly in half. After the cut, the cutter axis returns to the wait position. Synchronous control with electronic cam
operation is used for the cutter axis.
Axis 1
Roller
[Specification]
A one-time belt conveyor rotation generates the conveyor movement for one work piece.
(1) Cutter axis (cam control axis) specification
Ball screw lead (PB) : 10 mm
Gear ratio of the external reducer : 1/2
Cam stroke amount : 100.0000 mm
(2) Belt conveyor axis specification
Roller diameter : 50 mm (Roller circumference 50mm × π = 157079.6μm)
Gear ratio of the external reducer : 1/1 (Directly connect the servo motor to the roller)
[Machine operation pattern]
The cutter axis (Axis 1) moves for certain distance while synchronizing to the belt conveyor movement.
The cutter goes down in synchronization with the conveyor by sequence control, and the cutter returns to the original position
after the synchronization.
The belt conveyor moves at a constant speed.
