Chapter5.Function parameter
41
This parameter is related to the security protection of the inverter.
If this parameter is set to 1, if the time run command is effective when power on (for exa
mple, the terminal run command is closed before power on), the drive does not respond t
o the run command, you must firstly cancel the run command , after run command is agai
n effective the drive response. Prevent the danger occurs when power on or fault reset, m
otor repose to the run command unknowingly.
If this parameter is set to 0, the inverter power off without a fault condition (for example,
the terminal run command is closed before power on), the drive response to run command

5-1-9.F8 Group - Fault and protection
Overcurrent stall
protection current
In the process of the inverter acceleration, when the output current exceeds the
overcurrent stall protection current, the inverter stops ac/deceleration process and remains
in the current operating frequency, and then continues to ac/decelerate upon the decline of
the output current.
Overcurrent stall gain is used for adjusting inhibition overcurrent capability during
ac/deceleration. The greater this value, the stronger inhibition overcurrent capability
Under the premise that the overcurrent does not occur, the best is the smaller gain setting.
For the small inertia load, the overcurrent stall gain should be small, otherwise which
cause the slower system dynamic response. For the big inertia load, the overcurrent stall
gain should be large, otherwise the poor inhibitory effect may cause overcurrent fault.
When the overcurrent stall gain is set to 0, the overcurrent stall function will be
canceled.
Motor overload protection
Motor overload protection
gain
F8.02 = 0: no motor overload protection function, there may be the risk of damage to
the motor due to overheating, it is recommended that the thermal relay is installed
between the inverter and the motor;
F8.02 = 1: the inverter will determine whether the motor is overloaded or not
