B2.2.7 Controller Parameters
Use these parameters to set up the basic operation of the module, such as input
sampling period and controller mode, on a module-wide basis.

*1 The power frequency is set by default to the value set with the power frequency selector switch SW1-2. It can also be
selected with SW1-2. For details on how to do so, see Section A4.1, “Selecting Input Types and Power Frequency”. If the
power frequency is set using a hardware switch, the setting cannot be changed by software.
*2 This preset value imposes some restrictions on the number of loops that can be used. A value of 100ms allows up to 2
loops to be used, whilst a value of 200ms allows up to 4 loops to be used.
*3 This parameter is available only with F3CU04-1S. After selecting “Output preset value n” using the Output Terminal
Selection parameter, you must also specify a corresponding Output Preset Value (AOUTn) parameter value. (see also
Section B2.2.2, "Analog Output Settings").
*4 The F3CU04-0S module has only four output terminals. Thus, registers OUTSEL 5-8 are disabled and data range 21-28
is ignored.
The controller parameters must be enabled before any written content can take effect.
For details on how to enable these parameters, see Section B2.3, “How to Enable
Settings.”
Changing a controller parameter initializes other related parameters. Always set
controller parameters before setting I/O parameters and operation parameters.
You must observe some precautions when writing to the module. For details, see Section
B1.3, “Writing and Reading after Powering On.”
