B.3 Hierarchical Operating Lever Mode

Hierarchical operating lever mode wiring diagram is as follows:

If set P0.11=3, hierarchical operating lever mode is valid when hierarchical operating lever

is connected to the digital input I/O of inverter.

Digital terminal S1 and S2 control crane running up and down. If inverter receives two

directions simultaneously, it will coast to stop; keypad will not display the fault information.

Speed is given by multi-step function which supports up to 6 different speeds. Direction

command gives the first level contacts and the other five level contacts. Hierarchical

contacts can be connected to any digital input S terminal, corresponding speed given is

set by P1.00 to P1.05, and the system default setting is 4 levels.

Speed reference of hierarchical contacts should be switched on from low bit to high. The

higher contacts can be switch on only when lower ones areon. If the opposite situation

appears, inverter will display hierarchical operating lever fault and stops.

Operating lever zero position detection is valid, if you set P8.48=1, when inverter stopped,

it can be restart after operating lever back to zero position and P8.49 (delay time of

operating lever zero position).
