too fast or with too many fluctuations, select “fast heating environment” to slow down the control speed.
When bit2 ~ bit5 of S

+1 are all set as 1 or more than 1 environments are designated, FTC instruction will check
from bit2 to bit 5 in order and enable the function that has been set as 1. The parameter can be modified during
the control.

Output D22 (MV) of FTC instruction is the input D22 of GPWM instruction, as the duty cycle of ajustable pulses.
D30 is the fixed cycle time of pulses. See below for the timing diagram of Y0 output.
