7.16.4 Hierarchical joystick mode
The wiring diagram of hierarchical joystick mode is as follows:
A frequency reference Hierarchical multi-step speed reference
Hierarchical reference
Hierarchical reference
Hierarchical reference
Zero position signal
The mode is used in the case where the reference contact of the hierarchical joystick is connected to
the digital input I/O of the inverter. Set P19.00 to "3: Hierarchical joystick mode".
The forward and reverse direction signals of the hoist are given by S1 and S2, and the speed is given
by the hierarchical reference of multi-step speed terminals. The mode supports up to 6 different
speed levels: 1 contact at the 1
command. The hierarchical contact can be connected to the selected digital input S terminal and the
corresponding speed reference is given by mulit-step speed hierarchical reference 1~5
(P19.06~P19.11). The system is 4 gear speed by default and it can be regulated as required.
The hierarchical contacts of speed reference should close from lower to upper. Only when all lower
hierarchical contacts close can the upper hierarchical contacts close. If the lower hierarchical contacts
open while the upper hierarchical contacts close, the inverter will alarm hierarchical joystick fault and
stop.
The mode can select joystick zero postion detection. After stop, the inverter will not be allowed to
restart until the joystick returns to zero position (neutral position) and the time exceeds the defined
time in P19.28. When P19.27=1, detection enabling at joystick zero position is valid.
