Note: 1. The functions allocated to /S-ON, /P-CON. P-OT, N-OT, /ALM-RST, /P-CL, and /N-CL input
signals can be changed with parameters. (See 5.3.3 Input Circuit Signal Allocation.)
2. Pin numbers in parenthesis ( ) indicate signal grounds.
3. The voltage input range for speed and torque references is a maximum of ±12V.
