I/O Signal Names and Functions
The names and functions of the servo amplifier I/O signals are shown below.
The function assignments of the /S-ON, /P-CON, P-OT, N-OT, /ALM-RST, /P-CL, and /N-CL input sig-
nals can be changed by user parameter settings.
Pin numbers in parentheses show a signal ground.
The input voltage setting ranges for the speed reference and torque reference are ±12V (maximum).
