Confluence Master/Slave Selection
Control mode VF
Settings
 In a stand-alone system, this parameter is set as 0
 In a confluence system, the parameter is set as 1 for the Master and 2 for the Slave
 With multi-function input terminal function 45, the confluence/diversion can be configured. For
detailed operation, please refer to Chapter 2 for wiring and Chapter 3 for tuning.
 The difference between Master 2 and Master 3 is that the Master 3 can be configured as
confluent with other Slaves during confluence; however, the Master 2 can be configured for
stand-alone operation.
 When Pr.03-13 is set as 2: Slave, at the same time, Pr.01-01 will be set as 2 and Pr.03-15 will
be set as 1 automatically.
Slave's proportion of the Master's flow
Control mode VF
Settings
 This parameter setting is required only for the Master but not needed for the Slave.
 In a confluence system, this parameter value defines the Slave's portion of the Master's flow.
Example: Slave is 60L/min and Master is 40L/min, so the setting is 60/40 * 100% = 150%
For confluence of more than 2 pumps, 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%
 Source of frequency command
VF
Control mode
Settings
 This parameter is used for EMVJ-MF01.For detailed operation; refer to Chapter 3 for tuning.
 In a confluence system, if the Slave's frequency command is given through the RS485
communication, the setting value should be 1.
 Limit for the Slave reverse depressurization torque
Control mode VF
Settings
 Set the torque limit of the Slave when running reversely
Slave's activation level
Control mode VF
Settings
 This parameter setting is required only for the Master but not needed for the Slave.
 This parameter determines the activation level for the Slave. A 100% value corresponds to the
full flow of the Master.
