Goodrive270 series VFD for fan and pump Basic operation guidelines
-141-
1. Enable the multi-pump control function (P94.00=1).
2. Set the variable-frequency motor run mode to fixed (P94.10=0).
3. Set the motor quantity to 4 (P94.11=4).
4. Set RO5–RO8 to control motors A, B, C, and D respectively (set P26.06–P26.09 to 57–60
respectively).
5. Set the contactor closing delay, which is the interval of switchover between the variable-frequency
run mode and power-frequency run mode.
The following figures and tables show the control logic.
