TOEPYAIHV6002A HV600 Drive Programming
A positive PID input decreases the PID output (reverse acting).

b5-10: PID Output Gain Setting
No.

Description
Default
(Range)
b5-10
(01AE)
RUN
PID Output Gain Setting
Sets the amount of gain to apply to the PID output.
1.00
(0.00 - 25.00)
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.
(Hex.)
Name
Description
Default
(Range)
b5-11
(01AF)
PID Output Reverse
Selection
Sets the function that enables and disables reverse motor rotation for negative PID control output.
0
(0, 1)
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.
(Hex.)
Name
Description
Default
(Range)
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.
0.0 s
(0.0 - 6000.0 s)
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.
(Hex.)
Name
Description
Default
(Range)
b5-28
(01EA)
PID Feedback Square Root
Sel
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.
0
(0, 1)
0 : Disabled
1 : Enabled
