Functional Details 41
6: Frequency set channel selection 1
7: Frequency set channel selection 2
When the frequency input channel is set to be external terminal selection (F0.00=4),
the frequency set channel of the inverter will be determined by the status of these
two terminals, and for its corresponding relationship, please refer to description of
parameter [F0.00].
8: Free stop control
If terminal corresponding to this parameter is engaged, the inverter will lock outputt.
9: Three-line running control
When the running command terminal combination mode is set to three-line mode,
the external terminal defined by this parameter is inverter stop trigger switch. See
functional code [F0.02] for the three-line control mode in details.
10: DC braking control
At the inverter stop status, if the terminal defined by this parameter is engaged,
when the output frequency is lower than the DC braking initial frequency, the DC
braking function will be enabled until the terminal is disconnected. See description
of [F2.03] ~[F2.05] for relevant parameters of DC braking.
11: FWD control
12: REV control
13: Fault reset
When the inverter is at the faulty status, engaging the terminal set by parameter can
clear inverter’s fault.
14: Reserve
15: Reserve
16: External fault input
When the terminal set by this parameter is engaged, it indicates that the external
equipment is faulty. At this time, in order to ensure safety of the equipment, the
inverter will lock the input and displays the external fault signal Fu.16.
17: Disconnection input
When the terminal set by this parameter is engaged, it indicates disconnection fault
of external equipments. At this time, in order to guarantee equipment safety, the
inverter will lock output, and displays the external fault signal Fu.17.
