Chapter 4 Parameter Functions
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 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%
Source of frequency command
VF
Control mode
Settings
This parameter is used for EMVJ-MF01.For detailed operation, please 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
VF
Control mode
Settings
Set the torque limit for the Slave's reverse operation.
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.
Communication error treatment
Control mode VF
Settings
This parameter is used to set the handling status of the drive when a communication timeout
error (such as disconnection) occurs.
Time-out detection
Control mode VF
Settings
This parameter is used to set the time of the time-out event for the communication and the
keypad transmission.
