Chapter 4 Parameters|
4-164 Revision Jan. 2009, 06EE, SW--PW V1.12/CTL V2.12
This parameter will affect Pr.00.04(setting 5) directly. That is Pr.00.04(setting 5) Display PID
analog feedback signal value (b) (%)= PID detection value X Gain Over the PID Detection
Value.
Related parameters: Pr.00.04(Content of Multi-function Display) and Pr.10.01(Input Terminal
for PID Feedback)
10.12 PID Offset Level Unit: 0.1
Settings 1.0 to 50.0% Factory Setting: 10.0
This parameter is used to set max. allowable value of PID error.
10.13 Detection Time of PID Offset Unit: 0.1
Settings 0.1 to 300.0 sec Factory Setting: 5.0
This parameter is used to set detection of the offset between set point and feedback.
When the offset is higher than the setting of Pr.10.12 for a time exceeding the setting of
Pr.10.13, PID feedback signal fault occurs and operates by the treatment set in Pr.10.09.
Related parameters: Pr.10.00(PID Set Point Selection), Pr.10.01(Input Terminal for PID
Feedback), Pr.10.09(Treatment of the Erroneous PID Feedback Signals) and Pr.10.12(PID
Offset Level)
10.17
Minimum PID Output Frequency Selection
Factory Setting: 0
Settings 0 By PID control
1 By Minimum output frequency (Pr.01.05)
This is the source selection of minimum output frequency when control is by PID.
The output of the AC motor drive will refer to this parameter setting. When this parameter is
set to 0, the output frequency will output by the calculation of PID. When this parameter is set
to 1 and Pr.01.08 is not set to 0, the output frequency=Pr.01.08 setting. Otherwise, the output
frequency=Pr.01.05 setting.
Related parameters: Pr.01.05(Minimum Output Frequency (Fmin) (Motor 0)) and
Pr.01.08(Output Frequency Lower Limit)
10.14 Sleep/Wake Up Detection Time Unit: 0.1
Settings 0.0 to 6550 sec Factory Setting: 0.0
