Function
Connects the external input signal
Option Module.
Overtravel prohibited: Stops linear servomotor when mov-
able part travels beyond the allowable range of motion.
Connects the external input signal
Option Module.
Control power supply input for sequence signals.
Allowable voltage fluctuation range: 11 to 25 V
Note: The +24-V power supply is not included.
Connects the external input signal
Option Module.
Function
Turns OFF when an error is detected.
Controls the brake. The brake is released when the signal
turns ON.
Allocation can be changed to general-purpose output signals
(/SO1+, /SO1-).
General-purpose output signals
Note: Set the parameters to allocate functions.
