Motion Control - Omron sysmac NY532-1 00-111 13 0 Series Hardware User Manual

• Program the Input Data Invalid system-defined variable as an interlock condition in the user pro-
gram.
• Set the PDO communications timeout detection count setting in the EtherCAT master to at least 2.
Refer to the NY-series IPC Machine Controller Industrial Panel PC / Industrial Box PC Built-in
EtherCAT Port User's Manual (Cat. No. W562) for details.
• EtherCAT communications are not always established immediately after the power supply is turned
ON. Use the system-defined variables in the user program to confirm that communications are es-
tablished before attempting control operations.
• When an EtherCAT slave is disconnected or disabled, communications will stop and control of the
outputs will be lost not only for the disconnected slave, but for all slaves connected after it. Confirm
that the system will not be adversely affected before you disconnect or disable a slave.
• You cannot use standard Ethernet hubs or repeater hubs with EtherCAT communications. If you use
one of these, a major fault level error or other error may occur.
• Always use the specified EtherCAT slave cables. If you use any other cable, the EtherCAT master
or the EtherCAT slaves may detect an error and one of the following may occur.
• Continuous refreshing of process data communications will not be possible.
• Continuous refreshing of process data communications will not end during the set cycle.

Motion Control

• The motor is stopped if communications are interrupted between the Sysmac Studio and the product
during an MC Test Run. Connect the communications cable between the computer and product se-
curely and confirm that the system will not be adversely affected before you perform an MC Test
Run.
• 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.
• 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.
• Confirm the axis number carefully before you perform an MC Test Run.
• Use the NX_AryDOutTimeStamp (Write Digital Output Array with Specified Time Stamp) instruction
only after you confirm that InOperation from the MC_DigitalCamSwitch (Enable Digital Cam Switch)
instruction is TRUE.
• 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.
• If the value of OnCompensation or OffCompensation is equivalent to the time for half a rotation or
more, InOperation will be FALSE.
• If the value of OnCompensation results in exceeding LastOnPosition, the output timing will be un-
stable.
