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, the PID control fault occurs. The treatment will be done as Pr.08-09 setting.

PID Compensation Selection

Factory Setting: 0

Settings 0: Parameter setting (Pr.08-17)

1: Reserved

 Pr08-16=0: PID compensation value is given via Pr08-17 setting.

 Pr08-16=1: The PID compensation value is given via analog input (Pr03-00~03-02=13) and display

at Pr08-17(at this moment, Pr08-17 become read only).

PID Compensation

Factory Setting: 0

Settings -100.0~+100.0%

 The PID compensation value=Max. PID target value×Pr08-17. For example, the max. output

frequency Pr01-00=60Hz, Pr08-17=10.0%, PID compensation value will increase output

frequency 6.00Hz. 60.00Hz × 100.00% × 10.0% = 6.00Hz

Setting of Sleep Mode Function

Factory Setting: 0

Settings

0: Follow PID output command

1: Follow PID feedback signal

 When Pr08-18=0, the unit of Pr08-10 and that of Pr08-11 becomes frequency. The settings then

become 0~600.00Hz.

 When Pr08-19=1, the unit of Pr08-10 and that of Pr08-11 switches to percentage. The settings

then switch to 0~200.00%.

Wake-up Integral Limit

Factory Setting: 50.0

Settings 0.0~200.0%

 The wake-up integral limit of the VFD is to prevent sudden high speed running when the VFD

wakes up.

 The wake-up integral frequency limit= (01-00×08-19%)

 The Pr08-19 is used to reduce the reaction time from sleep to wake-up.

Enable PID to Change the Operation Direction

Factory Setting: 0

Settings 0: Disable change of direction

1: Enable change of direction
