P03
Node No.
The node No. 0 indicates the master
node.
A node No. ranging from 1 to 15
indicates a slave node.

P04
Slave count
When the node No. is 0, this parameter
indicates the number of slave nodes
connected to the master node.

P05
Node type
Specifies the working method of drive
on a node.
0: Independent unit. 1: Control unit. 2:
Following unit. 3: Flow-loop unit

P06
Flow switch-in
threshold
Specifies the condition for a next pump
to join the work. When the system flow
exceeds the flow switch-in threshold of
the working pump, a next pump is
asked to join the work.

P07
Flow switch-in
hysteresis upper
limit
Specifies the condition for a next pump
to join the work, used to prevent the
pump from repeated startup and
shutdown when the flow is at the
threshold.

P08
Flow switch-in
hysteresis lower
limit
Specifies the condition for a next pump
to join the work, used to prevent the
pump from repeated startup and
shutdown when the flow is at the
threshold.
