YASKAWA iQpump1000

After the first power-up, the real-time clock setup screen will appear automatically. Use the navigation buttons on the digital operator to set the date and time, then press 'Enter' to save. Once set, this screen will not reappear unless parameter o4-17 is reset.

First, power down the iQpump and wait at least five minutes for the charge indicator to extinguish. Then, swap any two of the three output leads (U/T1, V/T2, W/T3) connected to the motor. Reapply power and recheck the motor direction.

To enable automatic restart in Auto mode when operating from the digital operator, set parameter P4-10 to '1' (Enabled). This stores the run status and initiates a run command upon power-up after a power failure.

The Thrust Bearing function is primarily used for submersible pumps to prevent excessive motor wear. To enable it, set the minimum motor frequency in parameter P4-11 (e.g., 30.0 Hz for a 1800 RPM motor running at 3600 RPM base speed).

Ensure power is off, then remove the terminal cover. For a 2-wire, 4-20mA transducer, connect the output to terminal A3 and link AC-SN. For a 3-wire, 0-10V transducer, set the jumper inside the drive for 0-10V, connect the common signal to SN, and the output to A1.

First, ensure system stability under normal operation. Adjust P2-25 to the actual delta pressure drop plus 1 PSI in a no-flow situation. Then, run the system, monitor U1-99 'ANF Timer' to ensure it increments and resets. Create a no-flow situation to verify the timer holds at P2-24 time before the pump goes to sleep.
