5.3.2 I/O Signal Connector (CN1) Terminal Layout
The following diagram shows the layout of the CN1 terminals.
* 1. Make the signal allocations using parameters.
* 2. Connect a battery to CN1 or to a battery case. Connecting both batteries creates a loop circuit that is
dangerous between the two batteries.
Note: 1. The connector shell is connected to the FG (frame ground)
2. Do not use the unused terminals.
5.3.3 I/O Signal (CN1) Names and Functions
(1) Input Signals
Note: 1. The functions allocated to /DEC, P-OT, N-OT, /EXT1, /EXT2, and /EXT3 input signals can be
changed by setting the parameters.
2. For forward/reverse run prohibited, the SERVOPACK processing for stopping is executed by the
software. As the safety specifications of some applications may not satisfy local safety require-
ments, add the external safety circuits as required.
3. The signal /SI0 (pin No. 13) can be monitored as a general-purpose input with the
MECHATROLINK/MECHATROLINK II.
