Parameter Details

12.3 b: Application
YASKAWA SIEPC71061737D GA800 Drive Technical Reference 757
Note:
• This parameter is disabled when set to 0.0 Hz.
• When b5-53 > 0.0 Hz and the drive enables the integrator ramp limit, 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.
■ b5-55: PID Feedback Monitor Selection
No.
(Hex.)
Name Description
Default
(Range)
b5-55
(0BE1)
PID Feedback Monitor
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 Feedback Monitor Gain
No.
(Hex.)
Name Description
Default
(Range)
b5-56
(0BE2)
PID Feedback Monitor Gain
Sets the gain for the monitor set in b5-55 [PID Feedback Monitor Selection].
1.00
(0.00 - 10.00)
■ b5-57: PID Feedback Monitor Bias
No.
(Hex.)
Name Description
Default
(Range)
b5-57
(11DD)
PID Feedback Monitor Bias
Sets the bias for the monitor specified in b5-55 [PID Feedback Monitor 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 = 3E or 3F [MFDI Function Selection = PID Setpoint Selection 1/
2]. This value is a percentage of the maximum output frequency.
0.00%
(0.00 - 100.00%)
Table 12.28 shows how the different MFDI H1-xx values (3E and 3F) have an effect on the PID setpoint value.

OFF OFF No switch
ON OFF b5-58 [PID Setpoint2]
OFF ON b5-59 [PID Setpoint3]
ON ON b5-60 [PID Setpoint4]
■ b5-61: PID Trim Mode Lower Limit Sel
No.
(Hex.)
Name Description
Default
(Range)
b5-61
(119A)
PID Trim Mode Lower Limit
Sel
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
