FB52 System minimum pressure setting
Setting range: 0~50bar
Mfr’s value: 5
FA29 is used to set motor min speed when molding machine does not give any command. Proper minimum
speed will increase pressure response speed, but oil pump will act even when molding machine does not give
any command.
FB52 is used to set system bottom pressure when molding machine does not give any command. Proper
minimum pressure will increase pressure response speed.
FA30 System work mode
Setting range: 0, 1
Mfr’s value: 1
0 Speed and torque mode
Servo drive controls speed and torque of motor, the target frequency of motor is F203. When user needs to
study poles position of motor and judge whether motor and servo drive are normal, please select speed mode.
1 Pressure closed-loop mode
In this mode, servo drive can perform the control command of injection molding machine.
FB05 Plunger pump sloping switchover
Setting range: 0.00~17.50Mp
Mfr’s value: 10.00
Bevel angle of plunger pump swash plate could be adjusted by variation mechanism to change output capacity.
Variation mechanism is controlled by D01 or relay output. When system pressure reaches FB05, D01 will
output signal, swash plate control is valid.
FB13 Switchover point between low and
high pressure
Setting range:0
～
20.00Mp
Mfr’s value:8.00
FB14 Max reverse speed at low pressure
Setting range:0.000
～
0.300
( times the value of F805)
Subject to inverter model
FB15 Max reverse speed at high pressure
Setting range:0.000
～
0.300
( times the value of F805)
Subject to inverter model
When given pressure is higher than FB13, Max reverse speed is FB14, When given pressure is lower than
FB13, Max reverse speed is FB15.
Mfr’s value of FB14 and FB15 are the same.
