Chapter 12 Description of Parameter SettingsCP2000
12.1-08-8
PID Deviation Level
Default: 10.0
Settings 1.0–50.0%
PID Deviation Time
Default: 5.0
Settings 0.1–300.0 sec.
When the PID control function is normal, it should calculate the value within a period of time
that is close to the target value.
Refer to the PID control diagram for details. When executing PID feedback control, if |PID
reference target value – detection value| > Pr.08-13 PID deviation level and exceeds Pr.08-14
setting, it is judged as a PID control fault, and the multi-function output MOx = 15 (PID feedback
error) activates.
PID Feedback Filter Time
Default: 5.0
Settings 0.1–300.0 sec.
PID Compensation Selection
Default: 0
Settings 0: Parameter setting (Pr.08-17)
1: Analog input
0: The setting for Pr.08-17 gives the PID compensation value.
1: Set the analog input (Pr.03-00–Pr.03-02) to 13, then the PID compensation value of analog
input is displayed on Pr.08-17. At this time, Pr.08-17 is read only.
PID Compensation
Default: 0.0
Settings -100.0–100.0%
The PID compensation value = maximum PID target value × Pr.08-17. For example, if the
maximum operation frequency Pr.01-00=60.00 Hz, Pr.08-17=10.0%, the PID compensation
value increases the output frequency 6.00 Hz. 60.00 Hz × 100.00% × 10.0% = 6.00 Hz
Sleep Mode Function Setting
Default: 0
Settings 0: Refer to PID output command
1: Refer to PID feedback signal
0: The unit for Pr.08-10 and that for Pr.08-11 switch to frequency. The settings then are between
0–599.00 Hz.
1: The unit for Pr.08-10 and that for Pr.08-11 switch to percentage. The settings then are
between 0–200.00%.
