Compare
ZC 20
Compare a value to a range of
values (Analog, Direct Set, or FB
values)
Schmitt
trigger
ST 19
Turn an Input ON at the High Value
and OFF at the Low Value (or vice
versa)
Hour Meter HM 19
Records the accumulated time a
signal has been ON
Speed Detect SPD 25
The signal input frequency (On/Off)
is measured for a set length of time.
The frequency is compared to a
value range and the Output is turned
ON/OFF according to the result.
Pulse Width
Modulation
PWM 16
A continuous pulse train is output
when this function block is driven.
The characteristics of the pulse are
defined as; Pulse duty (Direct set,
Analog, FB values), cycle time.
Retentive
Alternate
RAL 13
Output alternates turning ON or OFF
with each input pulse. The last output
status is kept when the power supply
is cycled OFF and ON.
However, last output status is lost
when the
α2 series is placed in the
Stop mode.
Addition ADD 20 y = A + B
Subtraction SUB 20 y = A - B
Multiplication MUL 20 y = A × B
Division DIV 20 A ÷ B = q, r (quotient and remainder)
Calculation CAL *4
Equation using +, −, ×, ÷, % and the
selected data.
Shift SFT 19
Shift operation; When “SFT” signal is
input, last “I” signal status is output.
When using 8 bit shift operation,
“Shift” function block should be
continued 8 times.
