Count start point (b13)
See Sections 6.1.1 to 6.1.3.
This bit specifies the point at which counting of zero point
signals is started.
• When b13 = 0: Counting of zero point signals is
started when the DOG input is given
(when DOG input is turned on if b12
is set to 0 or when DOG input is
turned off if b12 is set to 1), the
pulse is stopped when the value N
set to the BFM #12 is reached, the
deviation counter clear signal is
output, and the home position (HP)
is written to the current position
(CP).
• When b13 = 1: Counting of zero point signals is
started when the DOG input is given
once, then stopped.
STOP input polarity (b14)
• When b14 = 0: The operation is stopped when the
input is turned on (OFF during

operation).
• When b14 = 1: The operation is stopped when the
input is turned off (ON during
operation).
This polarity changeover is valid exclusively for
the STOP input in the PGU.
STOP input mode (b15)
• When b15 = 0: The operation is interrupted when the
stop command is given (from the
PGU or the PC) during operation,
then the operation for the remaining
distance is restarted when the
restart command is given.
* However, if any BFM (except #25) is rewritten
while operation is interrupted by the stop
command, the operation for the remaining
distance will not be performed. Write the BFMs
by pulse operation (except the BFM #25).
• When b15 = 1: The operation for the remaining
distance is not performed, but the
next positioning is performed.
