Operands:
S
1
: Set value (SV) S
2
: Present value (PV) S
3
: Parameter (sampling time) D: Output
value (MV)
Explanations:
1. Range of S
1
: 1 ~ 5000 (shown as 0.1°C ~ 500°C). Unit: 0.1°. If (S
3
+1) is set as K0, the range
will be 0.1°C ~ 500°C.
2. Settings of parameter S
3
+1: bit0 = 0 ->°C; bit1 = 0 ->°F; bit1 = 0 -> no filter function; bit1 = 1 ->
with filter function; bit2 ~ bit5 -> 4 kinds of heating environments; bit6 ~ bit15 -> reserved. See
remarks for more information.
3. D is the value between 0 ~ sampling time × 100. When using this instruction, the user has to
adopt other instructions according to the types of the heater. For example, FTC can be used
with GPWM for output pulse control. “Sampling time × 100” is the cycle of GPWM pulse output;
MV is the width of GPWM pulse. See program example 1.
4. There is no limit on the times of using FTC instruction, but Do not repeatedly use a designated
operand in case an error may occur.
5. The models which are supported are DVP-ES2/EX2 v. 3.22, DVP-SA2/SX2 v. 2.66, and
DVP-SE v. 1.60 (and above).
Program Example:
1. Set up the parameter before executing FTC instruction.
2. When X0 = On, the instruction will be executed and and result will be stored in D150. When X0
= Off, the instruction will not be executed and the previous data remain unchanged.
