Version Information
If an NY-series Controller with unit version 1.14 or later and Sysmac Studio version 1.17 or
higher are combined, commands to the I/O devices can continuously be sent even when the
download process is in progress.
For the NY-series Controller with unit version 1.12 or earlier, sending commands to the I/O
devices is stopped when the download process is executed.
Refer to the NY-series Industrial Panel PC / Industrial Box PC Software User's Manual (Cat. No.
W558) for how to set to stop or continue sending commands to the I/O devices when the down-
load process starts.
Stopping sending commands to I/O devices
Servo is turned OFF during the download, and the axis status will be Disable (Axis Dis-
abled).
Continuing sending commands to I/O devices
The following status immediately before downloading is maintained during the download:
the Servo ON state for the MC_Power instruction and the output torque limit for the MC_-
SetTorqueLimit instruction.
The Servo ON state and torque limit are maintained even if the MC_Power and MC_Set-
TorqueLimit instructions are deleted from the user program after the program is updated by
downloading.
Overwriting MC Parameters with Programming Instructions
• You can use motion control instructions like the MC_Write (Write MC Setting), MC_ChangeAxes-
InGroup (Change Axes in Group) or MC_WriteAxisParameter (Write Axis Parameters) instruction
to change the settings of some of the MC parameters in the main memory while the user program
is running.
• If the specified set value is outside the valid range, the Error output variable from the instruction
changes to TRUE and the MC parameter setting is not changed.
• Changes to MC parameter settings become valid in either of the following two situations.
• The axis or axes group is stopped and you execute an instruction for an axis command or
axes group command.
• You set the Buffer Mode Selection for the instruction to Aborting and execute more than one
instruction.
• For details on MC_Write (Write MC Setting), MC_ChangeAxesInGroup (Change Axes in Group),
MC_WriteAxisParameter (Write Axis Parameters) and other instructions, refer to the NY-series
Motion Control Instructions Reference Manual (Cat. No. W561).
Precautions for Correct Use Precautions for Correct Use
• Changes to the MC Parameter Settings that are made with the MC_Write (Write MC Setting)
instruction are saved in the main memory in the Industrial PC. They are not saved in the built-
in non-volatile memory in the Industrial PC. Therefore, if you cycle the power supply or down-
load the settings from the Sysmac Studio, the parameter settings in the non-volatile memory
are restored. Also, you cannot upload the data in the main memory from the Sysmac Studio. If
you need to save settings to the non-volatile memory, use the Sysmac Studio to change the
parameter settings and then download those settings to the NY-series Controller.
• To maintain the MC_Power (Power Servo) and MC_SetTorqueLimit instructions after down-
loading, set Retain attribute of the input bits for the instructions to Retain.
• You can use the following instructions to change the settings of the MC parameters.
• MC_Write (Write MC Setting) instruction
• MC_ChangeAxesInGroup (Change Axes in Group) instruction
