5. Press the U Key to select on. off is the default.
6. To return to the initial setting level, press the O Key for at least one sec-
ond.
7. To return to the operation level, press the O Key for at least one second.
PID constants can be manually and individually set in the Proportional Band
(P), Integral Time (I), and Derivative Time (D) parameters, according to the
Display PID Selection parameter set in the PID setting level. Changing the
Proportional Band (P), Integral Time (I), or Derivative Time (D) parameter set-
tings in the adjustment level changes the settings in the current PID set. For
details on PID sets, refer to PID Sets on page 129.
In this example, the PID 2 Proportional Band parameter is set to 10.0, the PID
2 Integral Time parameter to 250, and the PID 2 Derivative Time parameter to
45.
1. Press the O Key to move from the operation level to the PID setting level.
2. Use the U and D Keys to set 2.
3. Press the M Key to select the PID 2 Proportional Band parameter.
4. Use the U and D Keys to set 10.0.
5. Press the M Key to select the PID 2 Integral Time parameter.
6. Use the U and D Keys to set 250.0.
7. Press the M Key to select the PID 2 Derivative Time parameter.
