b5-14: PID Feedback Low Detection Time
■
Sets the time that the PID feedback has to fall below b5-13 before feedback loss is detected.
No.
b5-14
b5-36: PID Feedback High Detection Level
■
Sets the feedback level used for PID feedback high detection. The PID feedback has to exceed this level for longer than
the time b5-37 before feedback loss is detected.
No.
b5-36
■ b5-37: PID Feedback High Detection Time
Sets the time for that the PID feedback has to exceed b5-36 before feedback loss is detected.
No.
b5-37
PID Sleep
■
The PID Sleep function stops the drive when the PID output or the frequency reference falls below the PID Sleep
operation level for a certain time. The drive will resume operating once the PID output or frequency reference rises above
the PID Sleep operation level for the specified time.
An example of PID Sleep operation appears in the figure below.
Figure 2.17
Notes on using the PID Sleep function
• The PID Sleep function is always active, even if PID control is disabled.
• The PID Sleep function stops the motor according to the stopping method in b1-03.
The parameters necessary that control the PID Sleep function are explained below.
b5-15: PID Sleep Function Start Level
■
Sets the level that triggers PID Sleep.
The drive goes into Sleep mode if the PID output or frequency reference is smaller than b5-15 for longer than the time set
in b5-16. It resumes operation when the PID output or frequency reference is above b5-15 for longer than the time set in
b5-16.
No.
