Signal name
• Near-point dog detection signal for a
DOG
machine zero point return
• Signal for the limit switch provided at
the upper limit of the stroke.
FLS
• Also used for the zero point return retry
function.
• Signal for the limit switch provided at
the lower limit of the stroke.
RLS
• Also used for the zero point return retry
function.
• Signal that stops positioning externally
• When stopping positioning, this signal
turns ON in 4ms or more.
STOP
• After this signal has been turned ON,
positioning is not restarted if this signal
is turned from ON to OFF.
• Signal that changes from speed control
CHG to position control in speed/position
changeover control.
• Signal that performs an external
positioning start/speed change/skip
request.
STRT • To make an external start valid, keep
this signal ON more than 4ms.
• Set which function will be used in the
detailed parameter.
COM • Input voltage 24VDC.
PULSER

Signal for judging whether the drive unit
is normal or abnormal.
ON : Drive unit normal. Positioning
READY
control enabled.
OFF : Drive unit abnormal. Positioning
control disabled.
• Enter the in-position signal from the
drive unit.
INPS
• The ON/OFF status can be monitored
with the remote input (RX).
COM • Input voltage 24VDC.
• Zero point signal for a machine zero
point return.
PG0
• Generally, the zero point signal of a
pulse encoder, etc. is used.
