7.4.5 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 8.3.2 Input Circuit Signal Allocation.
3. The voltage input range for speed and force references is a maximum of ±12 V.

Common
/S-ON 40 Servo ON: Turns ON the linear servomotor when the gate block in the inverter is
released. 9.6.1
/P-CON 41 Function selected by parameter. −
Proportional control
reference Switches the speed control loop from PI (proportional/
integral) to P (proportional) control when ON. 9.7.2
