Feedback Loss Detection
Select
Sets the drive response to PID feedback loss/excess. Sets drive operation after the drive detects PID
feedback loss/excess.

PID Feedback Loss
Detection Lvl
Sets the level that triggers PID Feedback Loss [FbL] detection as a percentage of the Maximum
Output Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]

PID Feedback Loss
Detection Time
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].

PID Sleep Function Start
Level
Sets the output level that triggers the PID Sleep function. Determined by A1-02
(0.0 - 590.0)
b5-16
(01B4)
PID Sleep Delay Time Sets a delay time to start or stop the PID Sleep function. 0.0 s
(0.0 - 25.5 s)
b5-17
(01B5)
RUN
PID Accel/Decel Time 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.

RUN
PID Output Lower Limit
Level
Sets the lower limit level for the PID control as a percentage of E1-04 [Maximum Output
Frequency].
When you use b5-34, set b5-91 = 0 [EZ Sleep Minimum Speed = 0 (Disabled)].
When you set the output lower limit level as Hz units or min
-1
(r/min) units, refer to page Missing
reference ID.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]

RUN
PID Input Limit Level Sets the output upper limit for the PID control as a percentage of the Maximum Output Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]

PID High Feedback
Detection Lvl
Sets the level that triggers Excessive PID Feedback [FbH] as a percentage of the Maximum Output
Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]

PID High Feedback
Detection Time
Sets the length of time that the PID feedback signal must be more than the level set in b5-36 [PID
Feedback High Detection Lvl] to cause Excessive PID Feedback [FbH].
1.0 s
(0.0 - 25.5 s)

PID User Unit Display
Scaling
Sets the value that the drive sets or shows as the PID setpoint when at the maximum output
frequency.
