DL100 Series Universal Low-Power Inverter
36 Detailed Description of Functions
0：Action only when decelerating
1：Not limited by deceleration
This parameter specifies the allowable lower limit voltage of the DC side when
the inverter is working normally. For some occasions where the power grid is low,
the undervoltage protection level can be appropriately reduced to ensure the
normal operation of the inverter.
Note: When the grid voltage is too low, the output torque of the motor will
decrease.
For the occasions of constant power load and constant torque load, too low grid
voltage will increase the input current of the inverter, thereby reducing the
reliability of the inverter operation.
This parameter specifies the threshold for voltage stall protection during motor
deceleration. When the pumping voltage on the DC side of the inverter caused by
deceleration exceeds the value specified in this parameter, the deceleration time
will be automatically extended. As shown in Figure 6-6.
