Basic Procedures for Using CX-Motion-MCH Support Software
• The following shows the ladder diagram that executes the present posi-
tion preset.
• MC Unit having the unit No. 0, the present position of Axis 1 is modified to
the preset values in DM100 and 101.

synchronization with Feedback value specified in the master axis classifica-
tion causes the MC Unit to operate the slave axis misconceiving that the mas-
ter axis moved from the position before the preset to the one after the preset.
Parameters in the servo driver can be edited using the Support Tool for MC
Unit. It is also possible to read or write data from or to the servo driver using
IORD/IOWR instructions of the CPU Unit.
These functions enable the PLC to manage the parameters of the servo
driver.
Refer to the servo driver's manual for more details.
Servo parameters operate with the setting saved in the servo driver. There-
fore, it will be required to setup parameters of a driver when the driver is
replaced.
1. Connect the servo driver and Motion Control Unit.
