Chapter 6 Description of Function Codes
Note:
By default, there is no overload protection below 110% of the rated current of the motor.
When you need to achieve overload protection below 110% of the rated current of the motor,
please set the motor overload protection current coefficient P9-35 appropriately.
Motor current percentage = (actual current/rated current) × P9-35
Example:
The user needs to set the protection time to 30.0min when the rated current is 90%, first find
in Figure 5-20 that the current corresponding to 30.0min on L1 is 130%, P9-35=(130%/90%)
×100% =144%. Note: The minimum current protection value is 55%.

This function is used to give an early warning signal to the control system before the motor
overload fault protection, so as to pre-protect the motor overload.
The larger the value is, the smaller the early warning is.
When the cumulative output current of the inverter is greater than the product of the set over-
load protection time and P9-02, the multi-function digital output terminal selects "motor over-
load pre-alarm ON" to output the switch signal. The terminal function is 6, see P6-00~P6-02
function code setting instructions for details.

< 1> This value is the factory value of 380V inverter, and the factory value of 200V inverter is
380V.
During the deceleration process of the inverter, when the DC bus voltage exceeds the overv-
oltage stall protection voltage, the inverter stops decelerating to maintain the current operat-
ing frequency, and continues to decelerate after the bus voltage drops.
Overvoltage stall gain, used to adjust the inverter's ability to suppress overvoltage during de-
celeration. The larger the value, the stronger the overvoltage suppression capability. Under
the premise of no overvoltage, the smaller the gain setting, the better.
