F8.06 Load speed display coefficient
This parameter is used to adjust the relationship between the output frequency of the inverter and the
load speed. For details, see the description of F8.12.
F8.07 temperature of IGBT
It is used to display the insulated gate bipolar transistor (IGBT) temperature of the Inverter module,
and the IGBT overheat protection value of the Inverter module depends on the model.
F8.09 Accumulative running time
It is used to display the accumulative running time of the inverter. After the accumulative running time
reaches the value set in F4.17, the terminal with the digital output function 12 becomes ON.
Number of decimal places
F8.12
for load speed display
F8.12 is used to set the number of decimal places for load speed display. The following gives an
example to explain how to calculate the load speed:
Assume that F8.06 (Load speed display coefficient) is 2.000 and F8.12 is 2 (2 decimal places). When
the running frequency of the inverter is 40.00 Hz, the load speed is 40.00*2.000 = 80.00 If the inverter is at
the stop state, the load speed is the speed corresponding to the set frequency, namely, "set load speed". If the
set frequency is 50.00 Hz, the load speed in the stop state is 50.00 * 2.000 = 100.000: 0 decimal place
1: 1 decimal place
2: 2 decimal places
3: 3 decimal places
F8.13 Accumulative power-on time
It is used to display the accumulative power-on time of the inverter since the delivery. If the time
reaches the set power-on time (F4.17), the terminal with the digital output function 24 becomes ON.
F8.14 Accumulative power consumption
It is used to display the accumulative power consumption of the inverter until now.
Group F9: Fault and Protection
F9.00 Motor overload protection selection
F9.01 Motor overload protection gain
F9.00 = 0: The motor overload protection is disabled. In this case, install a thermal relay between the
AC drive output (U, V, W) and the motor.
F9.00 = 1: The motor overload protection function has an inverse load-time characteristics.If the
motor overload current level and overload protection time need be adjusted, modify setting of F9.01.
