When the MFDI terminal set to PID Disable [H1-xx = 6A] activates, the drive disables fault detection.

b5-13 Fdback Loss Lvl
No.
Name
(Hex.)
b5-13 Fdback Loss Lvl
(01B1)
The drive detects PID Feedback Loss [FbL] when the feedback signal decreases to less than the level set in b5-13
for longer than the time set in b5-14 [Fdback Loss Time].

b5-15 Sleep Start Level
(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 [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.

(Hex.)
b5-17 PID Accel/Decel Time
(01B5)
The drive usually uses the acceleration and deceleration times set in C1: ACCEL / DECEL, 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 SS Cancel [H1-xx = 75].
■
b5-18 b5-19 PID SP Selection
No.
Name
(Hex.)
b5-18 b5-19 PID SP Selection
(01DC)
0 : Disabled
The drive does not use the value set in b5-19 as the PID setpoint.
1 : Enabled
The drive uses the value set in b5-19 as the PID setpoint.

V/f CL-V/f OLV CLV AOLV
Sets the level that triggers PID Feedback Loss [FbL] as a percentage of E1-04 [Max Output
Frequency].
V/f CL-V/f OLV CLV AOLV
Sets the length of time that PID Feedback must be less than b5-13 [Fdback Loss 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].
