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.

RUN
The drive usually uses the acceleration and deceleration times set in C1-xx [Accel and Decel Times], but when
PID control is enabled, the drive applies C1-xx after PID output. If you frequently change the PID setpoint, the
drive responsiveness decreases. When resonance with PID control causes hunting, overshoot, or undershoot, set
b5-17 for longer acceleration and deceleration times.
Decrease C1-xx until hunting stops, then use b5-17 to check the acceleration and deceleration. To enable and
disable the setting in b5-17 through an MFDI terminal, set PID Soft Starter Disable [H1-xx = 34].

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.
V/f CL-V/f OLV CLV AOLV
Sets the function that enables and disables b5-19 [PID Setpoint Value].
V/f CL-V/f OLV CLV AOLV
Sets the PID setpoint when b5-18 = 1 [b5-19 PID Setpoint Selection = Enabled].
