552 SIEPYEUOQ2A01A AC Drive Q2A Technical Manual
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.
■ b5-54 PID Softstarter Selection

PID Softstarter Selection
Sets how the soft-starter responds to PID input/output.

Soft Starter Input Soft Starter Output
Soft Starter 1 Frequency Reference Soft Starter Input PID Frequency Reference Output Output frequency
Soft Starter 2 Soft Starter Output Output frequency Frequency Reference PID Frequency Reference Input
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.
■ b5-55 PID Fback Mon Selection
No.

PID Fback Mon Selection
Sets the monitor for PID Feedback (Ux-xx).
000
(000 - 999)
Note:
• You cannot select parameter U5-xx.
• This parameter is disabled when set to 000.
■ b5-56 PID FdbkMon Gain
No.
(Hex.)
Name Description
Default
(Range)
b5-56
(0BE2)
PID FdbkMon Gain
Sets the gain for the monitor specified in b5-55 [PID Fback Mon Selection].
1.00
(0.00 - 10.00)
Note:
Set b5-18 = 1 [b5-19 PID SP Selection = Enabled] to enable this parameter.
■ b5-57 PID FdbkMon Bias
No.
(Hex.)
Name Description
Default
(Range)
b5-57
(11DD)
PID FdbkMon Bias
Sets the bias for the monitor specified in b5-55 [PID Fback Mon Selection].
0.00
(-10.00 - +10.00)
■ b5-58 to b5-60 PID Setpoint 2 to PID Setpoint 4
No.

RUN
PID Setpoint 2 to PID
Setpoint 4
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%.
