Function Parameter List
signal.
When the port receives a base blocking signal, the Inverter will immediately cut off the output of
the power module.
10 is NO input and 110 is NC input.
h) If the function code is set to 11, the corresponding port is used for input of output contactor
detection signals.
This function works only when B03 (zero speed time) > 0. This port receives output contactor
detection inputs to confirm the action of the output contactor. At elevator starting, the Inverter
begins output and the motor begins excitation after B07 delay when the output contactor action
is confirmed by the port. See B07 (contactor closing delay) in 6.2.2 B Parameters for more
information.
11 is NO input and 111 is NC input.
i) If the function code is set to 12, the corresponding port is used for input of fault reset
signals.
Upon any fault of the Inverter, the defined port receives a fault reset signal, and then the
Inverter may be reset (similar with F3 on the operator).
Note 2:
by default, the following input ports are defined for special inputs:
a) Input port for Inverter running signals
F07 = 7, DI7 as the upward signal input port;
F08 = 8, DI8 as the downward signal input port;
F09 = 9, DI9 as the running (enabling) signal input port;
b) Input port for multi-step speed giving commands
F03 = 3, DI3 as multi-step port 0;
F04 = 4, DI4 as multi-step port 1;
F05 = 5, DI5 as multi-step port 2.
