YASKAWA iQpump1000 - Delta Data Entry

u
Delta Data Entry
Delta Data Entry allows the user to set the Low and High Feedback Detection Levels relative to the current setpoint and
establish a PI setpoint when PID is not active.
Note: 1. This function is available in drive software versions PRG: 8552 and later.
2. Not available in drive models 4A0930 and 4A1200.

P1-11 High Feedback Level +0.0 to +999.9 0.0 to 999.9 (0.0 to 999.9) <– –> “+Add to SetPt”
The following conditions will change the setpoint in order of priority when the drive is a non-PID mode or when PID is
disabled:
The default Setpoint is Q1-01 (Setpoint 1)
1.
Setpoints Q1-02 to Q1-04 when Multi-setpoint Digital Inputs are active (H1-oo = 8D, 8E, 83, 84, or 85)
2. MEMOBUS Setpoint when MEMOBUS PID Setpoint enable bit is set
3. Pulse Input RP when H6-01 = 2 (PID Setpoint)
4.
Analog Input when H3-oo = C (PID Setpoint).
