Names and Functions
The four analog controls of the Analog Setting Board are located on the front
panel. The front panel does not have any indicators.
The value of the setting increases as the control is rotated clockwise. Use a
small Phillips screwdriver for this purpose.
Specifying IR 220 to IR 223 as the set value of a TIM instruction enables the
Board to be used as an analog timer. When the timer is started, the analog
settings are stored as the timer set value.
!Caution
While the power is turned ON, the contents of IR 220 to IR 223 are constantly
refreshed with the values of the corresponding controls. Be sure that these
words are not written to from the program or a Programming Device.
