Protection Function Parameter:f9 - SHENZHEN ENCOM ELECTRIC TECHNOLOGIES CO. enc eds800-2s0002n User Manual

F8.17 Reserved
Please set F8.01~F8.06 according to rated data of drived motor for safety.
6.10 Protection function parameter: F9
F9.00 Reserved
F9.01 failure self-restoration times
F9.02 failure self-restoration interval
During run process, failure will take place accidently due to load fluctuation
and the inverter will cut off output, here failure self-restoration function can be
applied in order to let the device continue to run. During self-restoration, the inverter
will try to resume running in speed checking restart mode but stop outputting and
failure protected if the inverter can't resume running successfully within set times.
Self-restoration function will be shut down if failure self-restoration times is set to 0.
(
1) To use failure self-restoration function must take device allowance and no essential
failure in the inverter as preconditions.
!
(2) Self-restoration function is ineffective to failure protection caused by overload and
over heat.
Motor overload protection mode selection
F9.03
This parameter defines protecting action mode when overload, overheat take
place in the inverter.
0: no action. No motor overload protection characteristic(apply with caution)，
here the inverter have no overload protection for load motor；
1: inverter cut off output at once. The inverter cut off output and motor stop
freely when overload, overheat take place.
motor overload protection coefficient
F9.04
This parameter sets sensibility of the inverter implementing thermal relay
protection to load motor, can implement correct heat protection to the motor by
setting this value when output current value of load motor don't match rated current
of the inverter, as shown in Fig.6-38.
Value of this parameter can be determined by following formula:
motor rated current
