VFD500 high performance vector control frequency inverter user manual

Functio

Parameter name

n code

K1-K4 Each represent DI multiple terminal 1-4 status ,O represent ineffective ,1 represent effective,M indicates

current output number of speed.Instructions of multiple speed combination

0: Combination method

M = K1 + (K2*2) + (K3*4) + (K4*8)

For example: K0=1,K1=0,K2=1,K3=0,Then M=5，current output fifth phase speed

1: Priority method Multiple speed output 0～4 phase speed，Priority K4＞K3＞K2＞K1。

For example: K4=1, then M=4;

K4=0,K3=1,then M=3;

K4=0,K3=0,K2=1,then M=2;

K4=0,K3=0,K2=0,K1=1, then M=1;

K1～K4 all to be 0, then M=0
