User-defined: Display actual motor speed in rpm
Control Mode
VF FOCPG
FOCPM
Factory setting: 0
Settings 0~39999rpm
Sets the hydraulic motor speed at 100% flow.
Maximum Value of Pressure Command
Control Mode
VF FOCPG
FOCPM
Factory setting: 250
Settings 0~250Bar
Sets the corresponding parameter value, 0-this value, of the controller pressure command 0-10V.
Maximum Value of Pressure Feedback
Control Mode
VF FOCPG
FOCPM
Factory setting: 250
Settings 0~400Bar
Sets the corresponding parameter value, 0-this value, of the pressure detection value 0-10V.
Pressure Control Mode
Control Mode
VF FOCPG
FOCPM
Factory setting: 0
Settings 0: Speed Control
1: Pressure Control
This parameter allows users to select the control mode of the Hybrid Servo Controller. It is strongly
advised that users should select the Speed Control Mode when using the controller for the first time.
This way, users can verify if there are errors in the hydraulic servo motor, oil pump, pressure sensor,
and system before switching to Pressure Control Mode to enter the full process control for the mold
injection machine.
Speed Bandwidth
Control Mode
FOCPG
FOCPM
Factory setting: 20
Settings 0~40Hz
Sets the speed response; the greater the value, the faster the response.
Pressure Feedback Filter Time PO
Pressure Feedback Filter Time PI
Pressure Feedback Filter Time QI
Control Mode
VF FOCPG
FOCPM
Factory setting: 0.000
Settings 0.000~1.000 sec
The analog signals input from the control terminals PO, PI, and QI usually contain noise. As noise will
affect control stability, input these signals to the filter to filter noise contained in the analog input signal.
When the filter time is too long, the control will be more stable, but the control response will be slower.
When the filter time is too short, the control response time will be faster, but the control will be less stable.
If users do not know the optimal filter time, adjust the filter time according to the instability or response
delay of control.
