Appropriate Ki value (time)
Ki value is too low (time)
Ki value is too high (time)
Appropriate Kd value
Kd value is too low
Kd value is too high
a
Base pressure
Control mode VF FOCPG FOCPM
Factory default: 1.0
Settings 0.0～100.0%
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.
a
Depressurization speed
Control mode VF FOCPG FOCPM
Factory default: 25
Settings 0～100%
Set the highest rotation speed at depressurization. The 100% value is mapped to Parameter 01-02
(the maximum rotation speed of the motor)
a
Ramp up rate of pressure command
a
Ramp down rate of pressure command
Control mode VF FOCPG FOCPM
Factory default: 100
Settings 0~1000ms
Ramp the pressure value for the pressure command so as to reduce the vibration of the machine.
Set the time required for ramping the pressure from 0~the maximum pressure (00-08).
