Chapter 4 Description of Parameters | VFD-VJ
4-55
03 Digital/Analog Input/ Output Parameters You can set this parameter during operation.
Multi-function input command 3 (MI3)
Multi-function input command 4 (MI4)
Multi-function input command 5 (MI5)
Control mode
VF FOCPG
FOCPM
Factory setting: 0
Settings 0: No function
44: Injection signal input
45: Confluence/Diversion signal input
46: Reserved
47: Multi-level pressure PI command 1
48: Multi-level pressure PI command 2
51: Flow rate mode
52: Multi-flow rate / speed command 1
53: Multi-flow rate / speed command 2
54: Multi-flow rate / speed command 3
When the value of this parameter is set as 44, the pressure feedback is lower than the pressure stable
region (please refer to the description of Pr.00-26) so the flow control will be performed.
When it enters the
pressure stable region, the pressure control will be performed.
If the setting value is 45, the confluence (OFF)/diversion (ON) function will be performed. For detailed
operation, please refer to Chapter 2 for wiring and Chapter 3 for tuning.
New protection mechanism at version C:: When Pr.03-00 ~ Pr.03-02 = 45, Pr.01-01 is
automatically set as 2 and Pr.03-15 is automatically, set as 1. This is a mechanism to prevent
forgetting to set up related parameters and mistakes when setting up parameters.
Please refer to the description Pr.00-36 if the setting value is 47 and 48,
When the setting value is 51 and when the pressure control mode is enabled (Pr.00-09=1), the speed
command is the flow command. The PI calculation is no longer required.
Digital input response time
Control mode
VF FOCPG FOCPM
Factory setting: 0.005
Settings 0.001~30.000 sec
This parameter is to delay and confirm the signal on the digital input terminal.
Digital input operation direction
Control mode
VF FOCPG FOCPM
Factory setting: 0
Settings 0~65535
This parameter defines the activation level of the input signal.
Bit 0 for the SON terminal, bit 2 for the EMG terminal, bit 3 for the RES terminal, bits 4~6 correspond to
MI3~MI5, respectively.

Multi-function Output 2 (MOI)
Control mode
VF FOCPG FOCPM
Factory setting: 0
Multi-function Output 3 (MO2)
Control mode
VF FOCPG FOCPM
Factory setting: 0
