Note) The default value is written when the execution condition turns on.
Output (MV) is output only in the ranges of upper limit value and lower limit value.
“Also, set to be as
−
1000
lower limit value < upper limit value
10000.”
How to output PWM.
The cycle of a PWM output is decided by the setting value of S4+4. The default value is periodic 1 second.
Duty of PWM is decided by the rate of the output MV (S4) that accounts for in the range of k0 to k10000.
When either on of the minimum value and maximum value of Output MV specified by S4+1 and S4+2 is a
negative value, the PWM output is always OFF.
A PWM output is always ON, when the output MV is k0, and it is always OFF when the output MV is k10000.
Explanation of specific usage
1: When changing control mode only with PWM output
Change the content of the control mode (S4+5) to k1 to k3 using an instruction such as F0(MV)
instruction.
(Example) Change the control mode to the proportional derivative type from the derivative type that is
the default.

: Set output lower limit value (S4+1) and output upper limit value (S4+2) according to the output
range of an analog output unit.
(Example) <Lower limit value=k0, upper limit value=k2000>, <Lower limit value=k0, upper limit
value=k4000>
