the ring topology, the transmission delay time is increased and the task execution time may be lon-
ger.
Version Information
The cable redundancy function can be used with project unit version 1.40 or later.
Motion control
• Confirm the axis number carefully before you perform an MC Test Run.
• The motor is stopped if communications are interrupted between the Sysmac Studio and the CPU
Unit during an MC Test Run. Connect the communications cable between the computer and CPU
Unit securely and confirm that the system will not be adversely affected before you perform an MC
Test Run.
• Always execute the Save Cam Table instruction if you change any of the cam data from the user
program in the CPU Unit or from the Sysmac Studio. If the cam data is not saved, the previous con-
dition will be restored when the power is turned ON again, possibly causing unexpected machine
operation.
• The positive drive prohibit input (POT), negative drive prohibit input (NOT), and home proximity in-
put (DEC) of the Servo Drive are used by the MC Function Module as the positive limit input, nega-
tive limit input, and home proximity input. Make sure that the signal widths for all of these input sig-
nals are longer than the control period of the MC Function Module. If the input signal widths are
shorter than the control period, the MC Function Module may not be able to detect the input signals,
resulting in incorrect operation.
• If you make any changes in the Detailed Settings Area of the
Axis Basic Settings
Display of the
Sysmac Studio, make sure that the devices or machines perform the expected operation before you
start actual operation.
If the relationship between the functions of the Motion Control Function Module and the EtherCAT
slave process data that is assigned to the axes is not correct, the devices or machines may perform
unexpected operation.
• Always use the axis at a constant velocity for the MC_DigitalCamSwitch (Enable Digital Cam
Switch) instruction.
If you set the Count Mode to Rotary Mode, the following operation will occur if you use OnCompen-
sation or OffCompensation and the axis velocity changes abruptly.
a) If the value of OnCompensation or OffCompensation is equivalent to the time for half a rotation
or more, InOperation will be FALSE.
b) If the value of OnCompensation results in exceeding LastOnPosition, the output timing will be
unstable.

c) If the value of OffCompensation results in exceeding FirstOnPosition, the output timing will be
