b5-47: PID Output Reverse Selection 2
No.
Name
(Hex.)
b5-47 PID Output Reverse
Selection 2
(017D)
This parameter is enabled when b5-01 = 3 or 4 [PID Function Setting = Fref+PID D=Fdbk, Fref+PID D=
Fdfwd].
0 : Disabled: 0 lower limit
Limits the PID output to zero when PID output is negative. The drive output will be stopped.
1 : Enabled: Negative lower limit
Rotates the motor in reverse when the PID output is negative.
■
b5-53: Integrator Ramp Limit
No.
Name
(Hex.)
b5-53 Integrator Ramp
Limit
(0B8F)
RUN
Note:
• This parameter is disabled when configured to 0.0 Hz.
• The PID integrator value is limited to the range defined by the output frequency ±b5-53 when the integrator ramp limit is enabled (b5-
53 > 0.0 Hz).
• Gradually reduce the value of b5-53 in increments of 0.1 Hz to slow down the response of PID control when the PID feedback changes
rapidly.
■
b5-54: PID softstarter cancel selection
No.
Name
(Hex.)
b5-54 PID softstarter cancel
selection
(0BB7)
The following illustrates the relationship between the soft starter and PID input/output.
Selection
Soft Starter 1
Soft Starter 2
0 : None
Performs the soft starter process downstream from the PID function. (The PID function input functions as the
frequency reference, the PID function output functions as the soft starter input, and the soft starter output
functions as the output frequency.)
1 : Softstarter is canceled
Performs the soft starter process upstream from the PID function. (The soft starter input functions as the
frequency reference, the soft starter output functions as the soft starter input, and the PID function output
functions as the output frequency.)
■
b5-55: PID feedback monitor selection
No.
Name
(Hex.)
b5-55 PID feedback
monitor selection
(0BE1)
630
V/f CL-V/f OLV
Sets whether or not the motor should rotate in reverse when the PID control
output is negative.
V/f CL-V/f OLV
Adjusts the responsiveness of PID control when the PID feedback changes
rapidly.
V/f CL-V/f OLV
Selects the relationship between the soft starter and PID input/output.
PID Frequency
Reference Input Reference Output
Frequency Reference
Soft Starter Output
V/f CL-V/f OLV
Selects the monitor (Ux-xx) used as the PID Feedback.
