Setting AC: PI2 Integral Hold
Locks the value of the secondary PI controller integral value.
Setting AD: Select PI2 Parameters
Uses the secondary PI controller Proportional and Integral adjustments (S3-06 and S3-07) instead of the primary PI controller
Proportional and Integral adjustments (b5-02 and b5-03). Only valid when S3-01 = 0 (secondary PI controller disabled).
Note:
This multi-function input has no effect on the secondary PI controller. It is only used for the primary PI controller (b5-oo).
Setting AE: BP Bypass Run
Commands a Run in Bypass mode via closing the BP Bypass Relay multi-function output.
Setting AF: Emergency Override Forward Run
Enables Emergency Override Forward Run. Refer to S6-01: Emergency Override Speed on page 153 and Refer to S6-02:
Emergency Override Reference Selection on page 153 for details.
Setting B0: Emergency Override Reverse Run
Enables Emergency Override Reverse Run. Refer to S6-01: Emergency Override Speed on page 153 and Refer to S6-02:
Emergency Override Reference Selection on page 153 for details.
Setting B1: Customer Safeties
The Customer Safeties multi-function input functionality is identical to Bypass Drive Enable (Setting 70: Drive Enable 2),
except for the following:
• When the input is open, the stopping method is forced to Coast to Stop
• If the input is open when the Run command is present, a “SAFE” alarm is displayed instead of the “dnE” alarm.
Setting B2: BAS Interlock
The BAS Interlock multi-function input is used in a damper interlock circuit to keep the drive from running until the damper
control relay is closed.
• When the input is open, the drive output is shut off (baseblocked).
• The drive will display an “inTLK” message if the input is open and a Run command is present. It will not display “dnE”.
• The state of the BAS Interlock multi-function input has no effect on the Emergency Override multi-function inputs
(H1-oo = AF, B0). The Emergency Override command will be accepted if the BAS Interlock digital input is open or closed.
