5–48 Programming Process PI [PI Ref Select] The source of the PI reference is selected with this parameter. The value from the selected reference is the “set point” for the Process PI regulator.

Response to loss of 4-20 mA signal is controlled by programming and requires the following: a) [Speed Control] must be set to “Process PI” and b) Either [PI Ref Select] or [PI Fdbk Select] must be set to “4-20 mA.” If both of the above conditions are met, the signal loss response is controlled by the setting of [4-20 mA Loss Sel]. If this parameter is set to “Stop/Fault,” loss of input will cause the drive to stop and issue a Hertz Err Fault. Loss of input while any other setting of [4-20 mA Loss Sel] is chosen will cause the drive to activate the alarm bit (bit 6 of [Drive Status] and bit 13 of [Drive Alarm]) and output programmed [Minimum Freq]. No signal loss protection is offered for the 0-10V input. [PI Fdbk Select] The source of the PI feedback is selected with this parameter. It identifies the input point for the process feedback device. [PI Reference] This parameter displays the current value of the reference selected by [PI Ref Select].
