You can allocate the input signal to use with a
parameter.
(Stops Servomotor drive (to prevent overtravel)
when the moving part of the machine exceeds the
range of movement.)
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 absolute
encoder backup battery.
Do not connect these pins if you use the Encoder
Cable with a Battery Case.
Inputs the analog signal that is output from the
gap sensor. Refer to the following section for
details on the connection.
