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.
Servo ON: Turns ON the servomotor when the gate block in the inverter is
released.
* Function selected via parameter.
Proportional opera- Switches the speed control loop from PI (proportional/
tion reference integral) to P (proportional) control when ON.
With internal reference speed selected: switches the
