Description:
This parameter defines how the control of the speed reference for the crane will be done.

P1023
Description
0
It defines that the speed reference will be controlled via the electronic potentiometer (EP) logic developed for the load
hoisting/forward, load lowering/reverse and load acceleration (increases the speed reference) commands.
1
It defines that there will be one speed reference controlled through the logic combination of the load hoisting/forward, load
lowering/reverse and 1
st
digital input for speed reference (DI4) commands.
2
It defines that there will be two speed references controlled through the logic combination of the load hoisting/forward, load
lowering/reverse and 1
st
digital input for speed reference (DI4) commands.
3
It defines that there will be three speed references controlled through the logic combination of the load hoisting/forward, load
lowering/reverse, 1
st
digital input for speed reference (DI4) and 2
nd
digital input for speed reference (DI5) commands.
4
It defines that there will be four speed references controlled through the logic combination of the load hoisting/forward, load
lowering/reverse, 1
st
digital input for speed reference (DI4) and 2
nd
digital input for speed reference (DI5) commands.
5
It defines that there will be five speed references controlled through the logic combination of the load hoisting/forward, load
lowering/reverse, 1
st
digital input for speed reference (DI4), 2
nd
digital input for speed reference (DI5) and 3
rd
digital input for
speed reference (DI6) commands.
6
It defines that the speed reference will be controlled via the value read by the analog input AI1, combined with the load
hoisting/forward and load lowering/reverse commands.
7
It defines that the speed reference will be written via a communication network and that the load hoisting/forward and load
lowering/reverse commands will be given through the network control word (P1022).
When the speed reference is selected through the logic combination of the DI4, DI5 and DI6 digital inputs, the
following truth table must be applied to obtain the speed reference.
