3.3 I/O Signal Connections
This section describes the names and functions of I/O signals (CN1). Also connection examples by control
method are shown.
3.3.1 I/O Signal (CN1) Names and Functions
The following table shows the names and functions of I/O signals (CN1).
(1) Input Signals
Note 1. The allocation of the input signals (P-OT, N-OT, /SI1, /SI4 to /SI6) can be changed. For details, refer to 3.4.1
Input Signal Allocations.
2. If the Forward run prohibited/ Reverse run prohibited function is used, the SERVOPACK or converter is stopped
by software controls, not by electrical or mechanical means. If the application does not satisfy the safety require-
ments, add an external circuit for safety reasons as required.
• The number of pins on the CN1 connector is different on a large-capacity Σ-V SER-
VOPACK (50 pins) and a standard Σ-V SERVOPACK (26 pins). If you are using both
types of SERVOPACK, use the correct connector model numbers when ordering and
the correct signal assignments.
• Regarding the allocation and use of I/O signals, they differ in accordance with the
connected option module. For details, refer to the manual for the command option
module that is connected.
