Parameter Description
Note: When P.110 = 3, the screen display shows two sections. A decimal point is used to separate the boundaries.
What is on the left is the target pressure of the constant pressure system and what is on the right is the
feedback pressure of the constant pressure system. As shown in this figure, , 20 denotes
that the target pressure of the constant pressure system is 2.0kg/cm

; 30 denotes that the feedback pressure
of the constant pressure system is 3.0kg/cm

Note: 1.The output mode selected by the value of P.151: when P.151 is 0, there is no output; when P.151 is 1, the
value of P152 is the voltage output dc voltage to keep the torque.
2. Suppose that P.152=6%, then the output voltage is P.19
6% at zero-speed.
5.41 Over Torque Detection (P.155~P.156)
P.155 “Over torque detection level”
P.156 “Over torque detection time”
Related parameters
P.40 “Multi-function output
terminal pattern”
P.85 “Function selection for
multi-function relay”
When the value of P.155 is not 0, the function of over torque detection is selected.
When the output current is in the excess of the over torque detection level P.155 and the over
torque detection time P.156, the display screen of the inverter will display
and the motor stops.
