F9 Group Fault And Protection - HNC Electric HV610 Series User Manual

F8 - 31 set count value
F8 - 32 specifies the count value
The count value needs to be collected through the multifunctional digital input terminal. The corresponding input
terminal function needs to be set to "counter input" (function 25) in the application. When the pulse frequency is high,
X5 port must be used.
When the count value reaches the set count value F8 - 31, the multifunction digital DO outputs the "set count
value reaches" ON signal, and then the counter stops counting
When the count value reaches the specified count value F8 - 32, the multifunction digital DO outputs the
"specified count value reaches" ON signal. At this time, the counter continues counting until "set count value" when
the counter stops.
The specified count value F8 - 32 should not be greater than the set count value F8 - 31. The count value can be
viewed in u0 - 12.
F9 - 00 motor overload protection selection
F9 - 01 motor overload protection gain
F9 - 00 = 0: motor overload protection is invalid.
F9 - 00 = 1: at this time, the frequency inverter judges whether the motor is overloaded according to the inverse
time limit curve of the motor overload protection.
The shortest time to report motor overload is 2 minutes. If you need to adjust motor overload current and time,
please Set F9 - 01 (motor overload protection gain). The curve of motor overload current and overload time is shown
in the following figure:
For example: if the motor is required to run at 120 % of the motor current for 30 minutes to report overload, the
default setting will be calculated first motor current IX overloaded for 30 minutes.
