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.
Pin
No.
Servo ON: Turns ON the servomotor when the gate block
40
in the inverter is released.
41
* Function selected via parameter.
Proportional Switches the speed control loop from PI
operation (proportional/integral) to P (proportional)
reference control when ON.
Direction With internal reference speed selected:
reference Switches the direction of rotation.
Control mode
switching
Zero-clamp Speed control with zero-clamp function:
reference reference speed is zero when ON.
Reference Position control with reference pulse stop:
pulse block stops reference pulse input when ON.
Forward Run
Overtravel prohibited: stops servomotor
42 prohibited
when movable part travels beyond the
43 Reverse Run
allowable range of motion.
prohibited
45
* Function selected with a parameter.
46
Forward
current limit ON
Current limit function used when ON.
Reverse
current limit ON
Internal
With internal reference speed selected:
speed
switches the internal speed settings.
switching
44 Alarm reset: Releases the servo alarm state.
Control power supply input for sequence signals: users
47
must provide the +24V power supply.
4 (2) Initial data request signal when using an absolute encoder.
21
Connecting pins for the absolute encoder backup battery.
