Setting 3: Digital output only, even if PID is disabled by digital input
Same as b5-12 = 0. Detection is still active even if PID is disabled by a digital input (H1- = 19).
Setting 4: Feedback loss alarm, even if PID is disabled by digital input
Same as b5-12 = 1. Detection is still active even if PID is disabled by a digital input (H1- = 19).
Setting 5: Feedback loss fault, even if PID is disabled by digital input
Same as b5-12 = 2. Detection is still active even if PID is disabled by a digital input (H1- = 19).
■
b5-13: PID Feedback Low Detection Level
Sets the feedback level used for PID feedback low detection. The PID feedback has to fall below this level for longer
than the time b5-14 before feedback loss is detected.
■
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.
■
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.
■
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.
■
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 5.26 PID Sleep Operation
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 that control the PID Sleep function are explained below.
