Note: If forward drive prohibition or reverse drive prohibition is used, the SERVOPACK is stopped by software con-
trols. If the application does not satisfy the safety requirements, add external safety circuits as required.

Function
Stops Servomotor drive (to prevent overtravel)
when the movable part of the machine exceeds
the range of movement.
Connects the deceleration limit switch for origin
return.
Stops Servomotor drive immediately and turns
OFF the servo in the SERVOPACK.
Inputs the sequence input signal power supply.
Allowable voltage range: 24 VDC ±20% The 24-
VDC power supply is not provided by Yaskawa.
These are the pins to connect the absolute
encoder backup battery.
Do not connect these pins if you use the
Encoder Cable with a Battery Case.
Inputs the overheat protection signal from a Lin-
ear Servomotor.
Function
Turns OFF (opens) when an error is detected.
Controls the brake. The brake is opened when
the signal turns ON (closes).
It remains ON continuously while a warning is
being detected.
This output is ON (closed) when the control
power supply and main circuit power supply are
ON and a servo alarm has not occurred.
Output the encoder divided pulse output sig-
nals with a 90° phase differential.
Outputs the origin signal once every encoder
rotation.
This is the 0-V signal for the control circuits.
Connected to the frame ground if the shield of
the I/O Signal Cable is connected to the con-
nector shell.
