Chapter 4 Parameter Functions
Pressure
Adjust the Kp value to a proper level first, and then adjust the Ki value (time). If the pressure
has overshoot, adjust the kd value.
Appropriate Kp value
Appropriate Ki value (time)
Kd value is too low
Base pressure
VF
Control mode
Settings
Set the minimum pressure value 100% corresponding to Parameter 00-08
Typically, it is necessary to maintain a certain base pressure to ensure that the oil pipe is in fully
filled condition so as to avoid the activation delay of the cylinder when a pressure/flow
command is activated.
Depressurization speed
VF
Control mode
Settings
Set the highest rotation speed at depressurization. The 100% value is mapped to Parameter
01-02 (the maximum rotation speed of the motor)
