The output D22 (MV) of the FTC instruction is used as the input to the GPWM instruction. D22
represents the pulse output width and D30 is the pulse output cycle. The timing chart for output Y0
is as follows.

The settings for the FTC instruction for this example are D10=k1500(target temperature),
D12=k60(sampling time is 6 seconds), D13=k8 (Bit 3=1) and D30=k6000 (=D12*100). The ladder
