1.2 b: Application
n b5-26: PI Maximum Boost Time
Associated with the Snooze Function. In cases where the temporary PI Setpoint (intended PI setpoint + PI Setpoint Boost)
cannot be reached within the PI Maximum Boost Time (b5-26), the Setpoint Boost is interrupted and the Drive output is turned
off.
No.
b5-26
n b5-27: PI Snooze Feedback Level
The second method of initiating the Snooze Function. The drive output shuts off when the PI feedback level exceeds the PI
Snooze Feedback Level (b5-27).
Normal drive and PI operation return after the PI feedback drops below the PI Snooze Deactivation Level (b5-24). Snooze
activates when both b5-22 and b5-27 conditions are met. There is no time delay for deactivation.
Sets as a percentage of maximum frequency.
No.
b5-27
n b5-28: PI Feedback Function Selection
When b5-28 is set to 1, the square root of the PI feedback is compared to the PI Setpoint to determine appropriate drive output
to properly regulate the system.
This is helpful in cases where the measured feedback is pressure, but the PI loop needs to regulate flow.
No.
b5-28
0: Disabled
1: Square Root
n b5-29: PI Square Root Gain
A multiplier applied to the square root of the feedback.
No.
b5-29
n b5-30: PI Feedback Offset
Sets PI feedback Offset as a percentage of maximum frequency.
No.
b5-30
n b5-34: PI Output Lower Limit
Sets the minimum possible PI controller output as a percentage of the maximum output frequency (E1-04). The lower limit is
disabled when set to 0.00%
No.
b5-34
n b5-35: PI Input Limit
Sets the maximum allowed PI input as a percentage of the maximum output frequency (E1-04). Parameter b5-35 acts as a
bipolar limit.
No.
