S: Input Word
Specifies the input word containing the input duty ratio or manipulated variable.
• Input duty ratio: 0000 to 2710 hex (0.00% to 100.00%)
• Input manipulated variable (See note.): 0000 to FFFF hex (0 to 65,535 max.) (Bits 00 to 03 of C spec-
ify the manipulated variable range, i.e., the number of valid bits in the manipulated variable. Specify
the same number of bits as specified for the output range setting in PIDAT(191).)
Note If S is a manipulated variable, specify the word containing the manipulated variable output from a
PIDAT(191) instruction.
C: First Parameter Word
Bits 04 to 07 of C specify the input type, i.e., whether the input word contains an input duty ratio or
manipulated variable. (Set these bits to 0 hex to specify a input duty ratio or to 1 hex to specify a manip-
ulated variable.)
The following diagram shows the locations of the parameter data.

Function
code
Inputs the duty ratio or manipulated variable from
the specified word, converts the duty ratio to a
685 time-proportional output based on the specified
parameters, and outputs the result from the speci-
fied output.
