4.1 Sequence Input Signals
This section provides information on the connections, functions, displays, and meaning of the sequence input
signals.
4.1.1 Connecting Sequence Input Signals
The connections of sequence input signals vary between stand-alone drives and NC systems as described
below.
J
M5A for Stand-alone Drives
Connect sequence input signals to the 6CN connector of the I/O card.
The sequence input signals can be input to the 6CN connector as 0 V, 24 V, or external common input sig-
nals. Refer to 3.4.4 Sequence Input Signal Circuits for details.
J
M5N for NC Systems
The Inverter performs serial transmission of sequence input signals with NC machines over YENET1200
communications. Refer to the manual for the NC machine for sequence input signals and input addresses.
4.1.2 Selecting Sequence Input Signals
Some functions of sequence input signals are selected by settings constants. Set the constants as shown
in the following table for the desired functions.
