4-23
Display the speed (rpm) defined by the user
Control mode
VF FOCPG FOCPM
Factory setting: 2500
Settings 0~39999 rpm
Set the maximum speed of the motor corresponding to the 100% flow.
When the control mode is FOCPM (Pr.01-00=5), Pr.00-06 will follow the setting at Pr.01-20<Number of
poles of the synchronous motor> to modify Pr.01-02<Motor’s maximum operating frequency>. frequency =
rpm*Pole/120
Maximum value of the pressure command
Control mode
VF FOCPG FOCPM
Factory setting: 140
Settings 0~400Bar
The 0~10V for the pressure command on the controller is mapped to 0~the value of this parameter.
When you set up Pr.00-07and Pr.00-08, these two parameters Pr.00-14 and Pr.00-15 will also be modified
automatically. However, when the pressure command is bigger than the pressure feedback, Pr.00-07
cannot be set up.
Only when Pr.00-07 is smaller than Pr.00-08, you can set Pr.00-07 while the hybrid servo drive is running,
.
Maximum pressure feedback value
Control mode
VF FOCPG FOCPM
Factory setting: 250
Settings 0~400Bar
The 0~10V for the pressure sensor is mapped to 0~the value of this parameter.
Pressure control mode
Control mode
VF FOCPG FOCPM
Factory setting: 0
Settings 0: Speed control
1: Pressure control
This parameter determines the control mode of the hybrid servo drive. It is recommended to use the speed
control at the initial startup. After the motor, pump, pressure sensor, and the entire system are checked
without any error, switch to the pressure control mode to enter the process control.
In pressure control(Pr.00-09=1), it is necessary to set bot Pr.01-05 (Acceleration time setting) and Pr.01-06
(Deceleration time setting) as zero, or it will affect the stability of pressure control
