(When the positing command for the block

preceding the cutting command is started,

the output is generated in accordance with

the cutting start coordinates.)

When parameter pm4011 D4 is set to 1, the constant peripheral speed control can also be exer-
cised for the positioning command. (However, only the spindle rotating speed based on the
positioning end point coordinates is output.)

#31107), SPINDLE CONSTANT SPEED INPUT

#31106), GEAR SHIFT STATE

OUTPUT

# 36503), AND SPINDLE CONSTANT SPEED STATE OUTPUT

# 36502)

inputs are used so that outputs other than the part program S command are deli-

vered to the

command analog output.

When the SSTP input is closed, the spindle motor rotaing speed command output based on

the spindle rotating speed specified by the part program is stopped.

If the GRS input is closed in this state, the voltage output defined by parameter GRSREV

is generated.

Further, if the GSC input is closed, the spindle motor rotating speed

command voltage output corresponding to the spindle rotating speed defined by parameter

is generated upon spindle gear range input.

While GRS or GSC based control is exercised, the GRSS or GSCS output is generated.
