6.3.3 I/O Signal (CN1) Names and Functions
(1) Input Signals
Note: 1. Pin numbers in parentheses () indicate signal grounds.
2. The functions allocated to /S-ON, /P-CON. P-OT, N-OT, /ALM-RST, /P-CL, and /N-CL input
signals can be changed by using the parameters. Refer to
7.3.2 Input Circuit Signal Allocation
.
3. The voltage input range for speed and torque references is a maximum of
±
12 V.
