The following speed selection table shows the different speeds and the according digital inputs.
* 0 = disabled, 1 = enabled, X = no meaning
Leveling Speed Priority is Selected and no Nominal Speed Input is Not Selected (H1-K80)
If d1-18 is set to “2” and no digital input is set for the nominal speed at no speed selection input the speed ref-
erence is nominal speed (d1-09). When the leveling speed signal is set, the inverter starts to decelerate to the
leveling speed. The leveling speed signal has priority over all other speed signals, i.e. the intermediate speed 1
and 2 and the releveling signals are disregarded when leveling speed is selected.
The inverter can be stopped by removing the Forward/Reverse command.
CAUTION: When the speed selection wires are broken, the nominal speed will be selected instead of stop.
The following speed selection table shows the different speeds and the according digital inputs.
* 0 = disabled, 1 = enabled, N/A = not available, X = no meaning
The intermediate speed 2 can not be selected using this configuration.
