168 YASKAWA TM.iQp.02 iQpump Drive Programming Manual
◆ P5 Pump Protection
■ P5-01 Hand Mode Reference
The iQpump drive can be operated manually or in the “Hand” mode. The frequency for the hand mode can be an analog input (0 ~ 10
Vdc) or from the digital operator (P5-02).
The hand mode operation is useful when testing the system during initial start-up without the automated regulation functions of the
iQpump drive.
The selection to determine the hand mode reference is determined by programming the Hand Mode Reference Source (P5-01). If P5-01 =
1, then the hand reference frequency is set by programming the Hand Reference (P5-02).
The Hand Mode Reference Source (P5-01) works in conjunction with the Hand Reference (P5-02) if P5-01 = 1.
The Hand Mode can be activated from the digital operator or by programming a multi-function digital input for “Hand Mode” (H1-xx =
80).
Note: To change the hand reference requires the P5-02 parameter to be programmed also. U1-01 will be the only monitor
available and the Up/Down arrow keys will not operate like a digital MOP.
