Yaskawa iQpump Micro - Manual (Page 140)

Setting 90: High Water Level
Function is active when the drive is running and depends on P1-31, High Water Digital Input Configuration, setting.
When P1-31 = 0 (N.O.): Closed: High Water Level Fault. Open: Reservoir/Tank is filled to normal level.
When P1-30 = 1 (N.C.): Closed: Reservoir/Tank is filled to normal level. Open: High Water Level Fault.
Setting 95: Remove Drive Disable
Prevents the drive from running when active for the time set in P4-26. Must be inactive for the time set in P4-27 to allow the
drive to run again.
Note: Parameter P4-25 determines whether this input is Normally Open or Normally Closed.
Setting B0: Emergency Override Function
The Emergency Override function is activated by closing the digital input programmed for Emergency Override Forward Run
(H1-oo = AF) or Emergency Override Reverse Run (H1-oo = B0).
If H1-oo = 6A (Drive Enable) is programmed, it must be opened to disable the drive for Emergency Override to take effect.
Closing both Emergency Override digital inputs at the same time will trigger an External Fault (EF) error.
When the drive is in Emergency Override, the frequency reference source is dependent on parameter S6-02, Emergency
Override Reference Selection. When S6-02 is set to 0 (Use S6-01 Reference), the drive will run at the S6-01 setting. When
S6-02 is set to 1 (Use Frequency Ref), the drive will use the currently selected frequency reference (based on b1-01 and HAND/
AUTO) as the run speed.
An alarm will flash during Emergency Override indicating that the function is active and the direction the drive is commanded
to run.
Resettable faults occurring when Emergency Override is activated will be cleared.
The drive will perform unlimited speed search retries during Emergency Override.
When Emergency Stop is active and Emergency Override is activated, the drive will run in Emergency Override mode.
The CALL (Serial Communication Error) mechanism is deactivated when Emergency Override is activated.
The Emergency Override function has priority over the PID Sleep feature (b5-15/b5-16).
Setting AF: Emergency Override Forward Run
Enables Emergency Override Forward Run (Enabled when S6-01 = 1).
Setting B0: Emergency Override Reverse Run
Enables Emergency Override Reverse Run (Enabled when S6-01 = 1).
n H2-01 to H2-03: Terminal MA/MB/MC, P1/PC, and P2/PC Function Selection
The drive has three multi-function output terminals.
No. Parameter Name Setting Range Default
H2-01 Terminal MA, MB and MC Function Selection (relay) 0 to 1AA E: Fault
H2-02 Terminal P1 Function Selection (open-collector) 0 to 1AA 37: During Frequency Output
H2-03 Terminal P2 Function Selection (open-collector) 0 to 1AA E: Fault
Setting 0: During Run
Output closes when the drive is outputting a voltage.
Status Description
Open Drive is stopped.
Closed A Run command is input or the drive is in deceleration or DC injection.
