Chapter 5 ParametersVFD-S Series

When this parameter is set to gain =1, PID output is Derivative time. At this time, error value – error value of the preceding item= additional respond speed and it is easy to have over compensation situation.

A-05

Upper Bound for Integral Control

Unit: 1

 

 

 

 

 

Settings

d0 to d100%

Factory Setting: d100

This parameter determines the Upper Bound for Integral Control while operating in the PID feedback loop. (Limit = 1-00×A-05 %). During a fast Integration response, it is possible for the frequency to spike beyond a reasonable point. This parameter will limit this frequency spike.

 

A-06

 

Primary Delay Filter Time

Unit: 2 msec

 

 

 

Settings

d0 to d999

Factory Setting: d0

 

 

 

 

Primary Delay Filter Time will slow down oscillation of the system.

 

 

 

A setting of d0 disables this function.

 

 

 

 

 

 

 

A-07

 

PID Output Frequency Limit

Unit: 1

 

 

 

 

 

 

 

 

 

Settings

d0 to d110%

Factory Setting: d100

 

 

 

 

 

 

 

This parameter determines the limit of the PID output frequency. If this parameter is set to 110%, then the maximum output frequency while in the PID operation will be (110% x Pr.01- 00) 66Hz.

A-08

Feedback Signal Detection Time

Unit: 0.1

 

 

 

 

 

Settings

d0.0 to d650 seconds

Factory Setting: d0.0

 

 

 

 

This parameter defines the detection time for the loss of a feedback analog signal. The drive will follow the operating procedure programmed in Pr.A-09 if the feedback signal is lost for more than the time set in Pr. A-08.

A setting of 0.0 disables this function.

A-09Treatment of the Erroneous Feedback Signals

 

 

Factory Setting: d0

Settings

d0

Warning and RAMP to stop

 

d1

Warning and COAST to stop
