Analog control (see page 
29) 
All CPU types are equipped with an analog potentiometer. It can be used in applications such 
as analog timers and does not require a programming tool. 
Thermistor input function (see page 
31) 
CPUs with product numbers ending in "TM" have a lead wire for thermistor input instead of an 
analog potentiometer. Changes in the thermistor's resistance can be loaded as analog input. 
Thermistors with a resistance value of 200Ω to 75kΩ can be used. 
Clock/calendar function (see page 
35) 
If an optional backup battery is installed in the FPΣ, a clock/calendar function is available. 
Positioning control using high-speed counter and pulse output (see page 
100) 
A high-speed counter and a pulse output function are provided as standard features. The 
pulse output function supports frequencies of up to 100kHz, which allows positioning control 
using a stepping or a servo motor. 
•  Measurement using high-speed counter (see page 
102) 
Incremental input mode, decremental input mode, two-phase input mode, 
incremental/decremental input mode, and incremental/decremental control mode are 
supported.
