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 - YASKAWA VARISPEED-616G5 Instruction Manual

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

Multi-step Speed References 1 through 3 and JOG Reference: "3" to "6"
J
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
D
change the status of these inputs to switch between the 9 frequency references.
