6.3.3.3 Derivative Time Settings [PAR2 → H-D/C-D]
In accordance with the deviation of the ramp, the time taken for the MV gained from
derivative operation to reach the MV gained from proportional control is called the
derivative time.

6.3.3.4 Control Period Settings [PAR3 → H-T/C-T]
 If relay or SSR is used to output MV under proportional control, the output is on for a
fixed amount of time (within the control period, as a percentage of the MV) and then
remains off for the rest of the time. The preset period when output ON/OFF takes
place is called the proportional control period.
 Control with SSR output has a faster response than that of relay output. Therefore, by
configuring a shorter control period, more responsive temperature control is achieved.
