4.6 Low Feedback Level Alarm and Fault Setup
80 YASKAWA TM.iQp.01 iQpump Drive User Manual
Figure 4.5 Low Feedback Timing Chart
Example: Constant Pressure System
System Units set to PSI (P1-02 = PSI)
System Setpoint set for 80 PSI
Pressure Transducer: 150 PSI
Desired Operation:
Pump System should show low feedback alarm when feedback level falls below 50 PSI and fault the system if the feedback level
stays there for more than 30 sec.
Solution: Program P1-07 to 50 PSI and P1-08 to 30 sec.
Note: Low feedback detection is only active during running in Auto Mode.
