12.2 b: APPLICATION
Note:
• This parameter is disabled when set to 0.0 Hz.
• When the integrator ramp limit is enabled (b5-53 > 0.0 Hz), the PID integrator value limit is the range set by the output frequency ±b5-
53.
• When the PID feedback changes quickly, gradually decrease the value of this parameter in increments of 0.1 Hz to decrease the speed
of the response of PID control.

Table 12.13 shows how the soft-starter responds to PID input/output.
Selection
Soft Starter 1
Soft Starter 2
0 : Disab PID Softstart
The soft starter process occurs 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 : Enab PID Softstart
The soft starter process occurs 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.

V/f CL-V/f OLV
Sets the monitor for PID Feedback (Ux-xx).
V/f CL-V/f OLV
Sets the gain for the monitor specified in b5-55 [PID Fback Mon Selection].
V/f CL-V/f OLV
Sets the bias for the monitor specified in b5-55 [PID Fback Mon Selection].
V/f CL-V/f OLV
Sets the PID setpoint when H1-xx = 77 or 78 [MFDI Function Select = PID SP Selection 1/2].
This value is a percentage where E1-04 [Max Output Frequency] setting = a setting value of
100%.
