2.3 b: Application
A positive PID input decreases the PID output (reverse acting).
■
b5-10: PID Output Gain Setting
No.
Name
(Hex.)
b5-10 PID Output Gain Setting
(01AE)
RUN
Applies a gain to the PID output and can help when b5-01 = 3 [PID Mode Setting = Fref + PID Trim].
■
b5-11: PID Output Reverse Selection
No.
Name
(Hex.)
b5-11 PID Output Reverse
Selection
(01AF)
When b5-01 = 3 [PID Mode Setting = Fref + PID Trim], this parameter is disabled. There is no limit for PID output.
The drive will operate the same as setting 1 [Negative Output Accepted].
0 : Lower Limit is Zero
When PID output is negative, PID output is limited to 0 and drive output is shut off.
1 : Negative Output Accepted
When the PID output is negative, the motor will rotate in reverse. When b1-04 = 1 [Reverse Operation Selection =
Reverse Disabled], the lower limit is 0.
■
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-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].
■
b5-28: PID Feedback Square Root Sel
No.
Name
(Hex.)
b5-28 PID Feedback Square Root
Sel
(01EA)
0 : Disabled
1 : Enabled
■
b5-29: PID Feedback Square Root Gain
No.
Name
(Hex.)
b5-29 PID Feedback Square Root
Gain
(01EB)
210
V/f OLV/PM OLV/PM EZOLV
Sets the amount of gain to apply to the PID output.
V/f OLV/PM OLV/PM EZOLV
Sets the function that enables and disables reverse motor rotation for negative PID control output.
V/f OLV/PM OLV/PM EZOLV
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 OLV/PM EZOLV OLV/PM
Enables and disables the square root of the PID Feedback compared to the PID Setpoint to set an
appropriate drive output for the correct system regulation.
V/f OLV/PM OLV/PM EZOLV
Sets the multiplier applied to the square root of the feedback.
