When the MFDI terminal set to PID Disable [H1-xx = 6A] activates, the drive disables fault detection.
4 : AL+DO@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 = 4] activates and the drive continues operation.
When the MFDI terminal set to PID Disable [H1-xx = 6A] activates, the drive disables fault detection.
5 : FLT+DO@PID Enable
The drive detects FbL and FbH. MFDO terminal NO-CM turns ON, NC-CM turns OFF, and the drive coasts to
stop.
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
No.
Name
(Hex.)
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.

b5-17: PID Accel/Decel Time
No.
Name
(Hex.)
b5-17 PID Accel/Decel Time
(01B5)
RUN
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].

V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the level that triggers PID Feedback Loss [FbL] detection as a percentage of the Maximum
Output Frequency.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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 OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the output level that triggers the PID Sleep function.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets a delay time to start or stop the PID Sleep function.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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.
