4. Description of Parameters
4-35
a
Multi-function output direction
Control mode VF FOCPG FOCPM
Factory default: 0
Settings 0~65535
 This parameter is used for bit-wise setting. If the corresponding bit is 1, the multi-function output is
set as reverse direction.
a
Low-pass filtering time of keypad display
Control mode VF FOCPG FOCPM
Factory default: 0.010
Settings 0.001~65.535 seconds
 This parameter can be set to reduce the fluctuation of the readings on the keyapd.
Maximum output voltage for pressure feedback
Control mode VF FOCPG FOCPM
Factory default: 10.0
Settings 5.0~10.0 V
Minimum output voltage for pressure feedback
Control mode VF FOCPG FOCPM
Factory default: 0.0
Settings 0.0~1.0V
 This parameter defines the pressure feedback output voltage type.
 If the pressure feedback has a bias, can adjust this parameter to eliminate the bias.
Reserved
Confluence Master/Slave Selection
Control mode VF FOCPG FOCPM
Factory default: 0
Settings 0: No function
1: Master 1
2: Slave/Master 2
3: Slave/Master 3
 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.
Slave's proportion of the Master’s flow
Control mode VF FOCPG FOCPM
Factory default: 100.0
Settings 0.0~65535.5 %
 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.
