5–49 Programming
[PI Feedback]
This parameter displays the current value of the
reference selected by [PI Fdbk Select].
Parameter Number 218
Parameter Type Read Only
Display Units / Drive Units 0.01 Hertz / 32767 = Maximum Freq Forward
Factory Default None
Minimum Value –400.00 Hz
Maximum Value 400.00 Hz
[PI Error]
The value of the error calculated by the PI loop. This
value is the difference between [PI Reference] & [PI
Feedback] and determines the PI output.
Parameter Number 219
Parameter Type Read Only
Display Units / Drive Units 0.01 Hertz / 32767 = Maximum Freq Forward
Factory Default None
Minimum Value –400.00 Hz
Maximum Value 400.00 Hz
[PI Output]
The current output of the PI loop is displayed with
this parameter. This output is used as the speed
command for process control or the speed adder for
process trim.
Parameter Number 220
Parameter Type Read Only
Display Units / Drive Units 0.01 Hertz / 32767 = Maximum Freq Forward
Factory Default None
Minimum Value –400.00 Hz
Maximum Value 400.00 Hz
[KI Process]
This parameter sets the integral gain of the process
PI loop.
Parameter Number 221
Parameter Type Read/Write
Display Units / Drive Units NA / NA
Factory Default 128
Minimum Value 0
Maximum Value 1024
[KP Process]
This parameter sets the proportional gain of the
process PI loop.
Parameter Number 222
Parameter Type Read/Write
Display Units / Drive Units NA / NA
Factory Default 256
Minimum Value 0
Maximum Value 1024
[PI Neg Limit]
This parameter sets the lower (negative) limit of the
PI output.
Parameter Number 223
Parameter Type Read/Write
Display Units / Drive Units 0.01 Hertz / 32767 = Maximum Freq Forward
Factory Default –8.33% of [Maximum Freq]
Minimum Value –400.00 Hz
Maximum Value 400.00 Hz
[PI Pos Limit]
This parameter sets the upper (positive) limit of the
PI output.
Parameter Number 224
Parameter Type Read/Write
Display Units / Drive Units 0.01 Hertz / 32767 = Maximum Freq Forward
Factory Default +8.33% of [Maximum Freq]
Minimum Value –400.00 Hz
Maximum Value 400.00 Hz
