12.2 b: APPLICATION
SIEPCYEUOQ2V01A Q2V Technical Manual 479
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 PID function input, and the PID function output functions as the
output frequency.
■ b5-55: PID Fback Mon Selection
No.
(Hex.)
Name Description
Default
(Range)
b5-55
(0BE1)
PID Fback Mon Selection
Sets the monitor (Ux-xx) used as the PID Feedback. Set the x-xx part of the Ux-xx [Monitor].
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 set in b5-55 [PID Fback Mon Selection].
1.00
(0.00 - 10.00)
■ 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 Setpoints 2 to 4
No.
(Hex.)
Name Description
Default
(Range)
b5-58 to b5-60:
(1182 - 1184)
RUN
PID Setpoints 2 to 4
Sets the PID setpoint when H1-xx = 77 or 78 [MFDI Function Selection = PID SP 1, PID SP 2].
This value is a percentage of the maximum output frequency.
0.00%
(0.00 - 100.00%)
Table 12.17 shows how the different MFDI H1-xx values (77 and 78) have an effect on the PID setpoint value.
Table 12.17 Switching of MFDI and PID Setpoint Value
H1-xx = 77 H1-xx = 78 PID Setpoint Value
OFF OFF No switch
ON OFF b5-58 [PID Setpoint 2]
OFF ON b5-59 [PID Setpoint 3]
ON ON b5-60 [PID Setpoint 4]
■ b5-61: PID LoLim Select for Trim Mode
No.
(Hex.)
Name Description
Default
(Range)
b5-61
(119A)
PID LoLim Select for Trim
Mode
Sets the function that adjusts the PID output in relation to the frequency reference.
0
(0, 1)
0 : Disabled
Does not adjust the PID output with the frequency reference.
1 : Enabled
Adjusts the PID output in relation to the frequency reference. The setting value of b5-62 [PID LoLim Value for
Trim Mode] sets the lower limit of the post-adjustment value. The maximum output frequency sets the upper limit.
