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%
a
Source of frequency command
Control mode VF FOCPG FOCPM
Factory default: 0
Settings 0: Digital Operation Panel
1: RS485 Communication
2~5: Reserved
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.
a
Limit for the Slave reverse depressurization torque
Control mode VF FOCPG FOCPM
Factory default: 20
Settings 0~500%
Set the torque limit for the Slave’s reverse operation.
Slave’s activation level
Control mode VF FOCPG FOCPM
Factory default: 50
Settings 0~100%
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.
a
Communication error treatment
Control mode VF FOCPG FOCPM
Factory default: 0
Settings 0: Warn and keep operation
1: Warn and ramp to stop
2: Warn and coast to stop
3: No action and no display
This parameter is used to set the handling status of the drive when a communication timeout error
(such as disconnection) occurs.
a
Time-out detection
Control mode VF FOCPG FOCPM
Factory default: 0.0
Settings 0.0~100.0 seconds
