Delta VFD300VL43A-J - Page 89

4-36
Example: Slave is 60L/min and Master is 40L/min, so the setting is 60/40 * 100% = 150%
For confluence of more than 2 pump, the values for the slaves must be the same. For
example, if the total flow for a three-pump system is 200L/min, where the Master is 40L/min,
then the two Slaves should be 80L/min. The setting of Parameter 03-14 should be 160/40 =
400%
