YASKAWA VARISPEED-616G5 - 3-Wire Sequence (Forward;Reverse Run Commands): “0”; 3-Wire Sequence Wiring Example; Multi-Step Speed References 1 through 3; JOG Reference; Timing Chart for 3-Wire Sequence

Basic Operation
6.1.8 Multi-function Input Settings: H1-01 through H1-06
6-14
J 3-wire Sequence (Forward/Reverse Run Commands): “0”
D
When a value of “0” is set for any one of the multi-function inputs (H1-01 through H1-06), 3-wire se-
quence control is used and the multi-function input terminal for which “0” was set becomes the for-
ward/reverse run command terminal.
D
When the Unit is initialized for 3-wire sequence control with A1-03 , multi-function input 3 (terminal
5) becomes the input terminal for the forward/reverse run command.

J Multi-step Speed References 1 through 3 and JOG Reference: “3” to “6”
D
Eight frequency references and one jog frequency reference can be used.
D
Set the multi-step speed references 1, 2, and 3 and the JOG reference for the multi-function inputs, and
change the status of these inputs to switch between the 9 frequency references.

H1-03 3
Multi-step speed reference 1 (Also used for master-speed/auxiliary-speed
switching when an auxiliary reference is set for the multi-function analog
input in H3-05.)

H1-04 4 Multi-step speed reference 2

HI-05 5 Multi-step speed reference 3
8
H1-06 6
JOG reference (This setting has higher priority than the multi-step speed
reference.)
