Control mode selection
Select a control mode. Depending on this setting, the control method of each channel changes as follows:

• When the control mode has been changed, all items are overwritten with default values. Change each
parameter setting if necessary.
• A set value discrepancy error (control mode) (error code: 1910H) occurs right after the control mode
change. To clear the error, turn from OFF to ON 'Setting value backup command' (Y8) and register the
parameter after the change in the non-volatile memory.
■Buffer memory address
The following shows the buffer memory address of this area.

Control mode selection
Control mode selection (in the Q compatible mode)
■Default value
The default value is Standard control (0).
Sampling cycle selection
Select one of the following sampling cycles:
• 0: 500ms/4 channels
• 1: 250ms/4 channels
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory area name
Sampling cycle selection
■Default value
The default value is 500ms/4 channels (0).
A set value discrepancy error (sampling cycle) (error code: 1930H) occurs right after the sampling cycle
change. To clear the error, turn from OFF to ON 'Setting value backup command' (Y8) and register the
parameter after the change in the non-volatile memory.
