Chapter 4 Parameter Functions
Reserved
Over-pressure detection level
VF
Control mode
Settings
When the pressure feedback exceeds this parameter setting, an "ovP over pressure" error
message may occur.
Firmware version 2.04 and above, maximum value 400Bar, the previous version's maximum
allowed value is 250Bar.
Detection of disconnection of pressure feedback
Control mode VF
Settings
When this parameter is set as 1 and if the pressure feedback signal is below 1V or 4mA, an
"Pfbf pressure feedback fault" error message may occur.
Pressure/flow control function selection
Control mode VF
Settings
When the Bit 0 of this parameter is set as 1, the PI Gain for the pressure can be switched in
conjunction with the multi-function input terminal
Pr. 03-00~03-02 d= 47
OFF
ON
OFF
When the Bit 1 of this parameter is set as 1, the pressure feedback is lower than the pressure
stable region (please refer to the description of Parameter 00-26) so the flow control will be
performed. When it enters the pressure stable region, the pressure control will be performed.
Integration Time – Pressure Overshoot 1
VF
Control mode
Settings
Level of the pressure overshoot
Control mode VF
Settings
By using the factory setting 250 bar of the Pr00-08 Maximum Pressure Feedback, when the
pressure is over 5 bar (250*2%=5 bar), another integral time of Pr00-39 will do overshoot
protection.
When Pr00-38=1 and Pr00-39=0,Pr00-42 is disable.
