Chapter 4 Parameters|
4-54 Revision Nov. 2008, VLE1, SW V1.03
Parameters 03-03 to 03-11 are used when the source of frequency command is the analog
voltage/current signal.
03-12 Analog Input Delay Time (AUI1) Unit: 0.01
Control
mode
VF VFPG SVC FOCPG TQCPG FOCPM
Factory setting: 0.01
03-13 Analog Input Delay Time (ACI) Unit: 0.01
Control
mode
VF VFPG SVC FOCPG TQCPG FOCPM
Factory setting: 0.01
03-14 Analog Input Delay Time (AUI2) Unit: 0.01
Control
mode
VF VFPG SVC FOCPG TQCPG FOCPM
Factory setting: 0.01
Settings 0.00 to 2.00 sec
Interferences commonly exist with analog signals, such as those entering AUI, ACI and AUI2.
These interferences constantly affect the stability of analog control and using the Input Noise
Filter will create a more stable system.
If Pr. 03-14 is large, the control will be stable, yet the response to the input will be slow. If Pr.
03-14 is small, the control may be unstable, yet the response to the input will fast.
03-15 Loss of the ACI Signal
Control
mode
VF VFPG SVC FOCPG TQCPG FOCPM
Factory setting: 0
Settings 0 Disable
1 Continue operation at the last frequency
2 Decelerate to stop
3 Stop immediately and display E.F.
This parameter determines the behavior when ACI (4-20mA) is lost.
03-16 Reserved
03-17 Analog Output Selection 1
03-20 Analog Output Selection 2
Factory Setting: 0
Settings 0-20
