When the feedback signal is less than the level set in b5-13 for the time set in b5-14, the drive detects FbL.
When the feedback signal is less than the level set in b5-36 for the time set in b5-37, the drive detects FbH.
3 : Digital Out Only, @ PID Enable
The MFDO terminal set for PID Feedback Low or PID Feedback High activates. The keypad will not show a minor
fault/alarm. The drive continues operation.
When the MFDI terminal set to PID Disable [H1-xx = 19] activates, the drive disables fault detection.
4 : Alarm + Digital Out, @PID Enable
The drive detects FbL and FbH. The MFDO terminal set for PID Feedback Low or PID Feedback High activates. The
output terminal set for Alarm [H2-01 to H2-03 = 10] activates and the drive continues operation.
When the MFDI terminal set to PID Disable [H1-xx = 19] activates, the drive disables fault detection.
5 : Fault + Digital Out, @PID Enable
The drive detects FbL and FbH. Fault relay output terminal MA-MC activates, MB-MC turns OFF, and the drive
coasts to stop.
When the MFDI terminal set to PID Disable [H1-xx = 19] activates, the drive disables fault detection.

(01B3)
The drive goes into Sleep mode when the PID output or frequency reference is less than b5-15 for longer than the
time set to b5-16 [PID Sleep Delay Time]. The drive continues operation when the PID output or frequency reference
is more than b5-15 for longer than the time set to b5-16.

V/f CL-V/f OLV CLV AOLV
Sets the level that triggers PID Feedback Loss [FbL] detection as a percentage of the Maximum
Output Frequency.
V/f CL-V/f OLV CLV AOLV
Sets the length of time that PID Feedback must be less than b5-13 [PID Feedback Loss Detection
Lvl] to detect PID Feedback Loss [FbL].
V/f CL-V/f OLV CLV AOLV
Sets the output level that triggers the PID Sleep function.
V/f CL-V/f OLV CLV AOLV
Sets a delay time to start or stop the PID Sleep function.
V/f CL-V/f OLV CLV AOLV
Raises or lowers the PID setpoint using the acceleration and deceleration times set to the drive. This
is a soft-starter for the PID setpoint.
