I/O Signal Connections
This section describes the names and functions of I/O signals (CN1). Also, connection examples by control
method are shown.
3.2.1
I/O Signal (CN1) Names and Functions
The following table shows the names and functions of I/O signals (CN1).
(1) Input Signals
∗
Refer to the manual of the connected Command Option Module for information on how to allocate and use I/O signals.
Note 1. The functions allocated to /SI3, P-OT, N-OT, /SI4, /SI5, and /SI6 input signals can be changed by using the
parameters. Refer to
3.3.1 Input Signal Allocations
.
2. If the Forward run prohibited/Reverse run prohibited function is used, the software can be used to stop the SER-
VOPACK. If the application does not satisfy the safety requirements, add an external circuit for safety reasons as
required.
(2) Output Signals
Note: For more information on the allocation of /SO1, /SO2, and /SO3, refer to
3.3.2 Output Signal Allocation.
