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
You can allocate the input signal to use
with a parameter.
(Stops Servomotor drive (to prevent over-
travel) when the moving part of the
machine exceeds the range of move-
ment.)
You can allocate the input signal to use
with a parameter.
(Connects the deceleration limit switch for
origin return.)
You can allocate the input signals to use
with parameters.
(Connect the external signals that latch
the current feedback pulse counter.)
You can allocate the input signal to use
with a parameter.
(Used for general-purpose input. You can
monitor this signal in the I/O monitor field
of MECHATROLINK.)
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 abso-
lute 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 Linear Servomotor.
