Chapter 12 Description of Parameter Settings|CFP2000 Series
12.1-08-6
Feedback Signal Detection Time
Factory Setting: 0.0
Settings 0.0~3600.0 sec
Pr.08-08 is valid only for ACI 4-20mA.
This parameter sets the detection time of abnormal PID feedback. If detection time is set to 0.0,
detection function is disabled.
Feedback Signal Fault Treatment
Factory Setting: 0
Settings 0: Warn and keep operation
1: Warn and ramp to stop
2: Warn and coast to stop
3: Warn and operate at last frequency
This parameter is valid only for ACI 4-20mA.
AC motor drive acts when the feedback signals analog PID feedback is abnormal.
Sleep Reference
Factory Setting: 0.00
Settings 0.00~599.00Hz or 0~200.00%
Setting value of Pr.08-10 determines if sleep reference and wake-up reference is enable or
disable. When Pr.08-10 = 0, it means disable. When 08-10 ≠ 0, it means enable.
Wake-up Reference
Factory Setting: 0.00
Settings 0.00~599.00Hz or 0~200.00%
When Pr.08-18 = 0, the unit of Pr.08-10 and that of Pr.08-11 become frequency. The settings then
become 0.00~599.00 Hz.
When Pr.08-18=1, the unit of Pr.08-10 and that of Pr.08-11 switch to percentage. The settings
then switch to 0~200.00%.
And the percentage is based on the input command not maximum. E.g. If the maximum is 100
Kg, the command now is 30kg, if 08-11=40%, the value is 12kg.It is the same as Pr.08-10.
Sleep Time
Factory Setting: 0.0
Settings 0.00~6000.0 sec
When the frequency command is smaller than the sleep frequency and less than the sleep time,
the frequency command is equal to the sleep frequency. However the frequency command
remains at 0.00Hz until the frequency command becomes equal to or bigger than the wake-up
frequency.
PID Deviation Level
Factory Setting: 10.0
Settings 1.0~50.0%
