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, /N-CL, and /P-DET input signals
can be changed by using the parameters. Refer to 3.3.1 Input Signal Allocations.
Servo ON/OFF: Turns ON/OFF the servomotor.
Function selected by parameter.
Proportional control Switches the speed control loop from PI (proportional/
reference integral) to P (proportional) control when ON.
For the internal set speed selection: Switches the movement
Direction reference
direction.
Position ↔ speed
Control switching Position ↔ force
Force ↔ speed
Speed control with zero-clamp function: Reference
Zero-clamp reference
speed is zero when ON.
Reference pulse Position control with reference pulse stop: Stops reference
block pulse input when ON.
Forward run
prohibited, Overtravel prohibited: Stops servomotor when movable part
Reverse run travels beyond the allowable range of motion.
prohibited
Function selected by parameter.
Forward external
force limit ON,
Force limit function used when ON.
Reverse external
force limit ON
Internal speed With internal reference speed selected: Switches the
switching internal speed settings.
Alarm reset: Releases the servo alarm state.
Control power supply input for sequence signals: The 24 V power supply is not
included.
Allowable voltage fluctuation range: 11 to 25 V
Initial data request signal when using an absolute encoder.
Inputs speed reference. Input voltage range: ± 12 V max.
Input pulse modes: Set one of them.
• Sign + pulse string
• CCW/CW pulse
• Two-phase pulse (90° phase differential)
Reference pulse input for only line driver
Position error pulse clear: Clears position error pulse during position control.
Inputs force reference. Input voltage range: ± 12 V max.
Function
Enables control switching.
