(9) In the following cases, a program error will occur.
(a) Items common for type 1 and 2
Settings
Command
range (Unit)
Error
End point
coordinate
Range of
coordinate
command
(mm/inch)
(Decimal point
command is
possible.)
• If a value exceeding the command range is issued,
program error (P35) will occur.
• If an axis other than one which can be controlled
with the command system is commanded, a
program error (P33) will occur.
Arc center
Range of
coordinate
command
(mm/inch)
(Decimal point
command is
possible.)
• If a value exceeding the command range is issued,
a program error (P35) will occur.
• If an axis other than one which can be controlled
with the command system is commanded, a
program error (P33) will occur.
• If rotation plane axis is not designated completely, a
program error (P33) will occur.
Number of
pitches
0 to 99
• If a value exceeding the command range is issued,
a program error (P35) will occur.
Feedrate
Range of speed
command
(mm/min,inch/mi
n)
(Decimal point
command is
possible.)
• If a value exceeding the command range is issued,
a program error (P35) will occur.
(b) Items for type 2 only
Settings
Command
range (Unit)
Error
Increment/
decrement
amount of
radius
Range of
coordinate
command
(mm/inch)
(Decimal point
command is
possible.)
• If the sign of designated increment/decrement
amount is opposite from that of the difference
between the start point radius and the end point
radius, a program error (P33) will occur.
• If the end point position obtained from the speed
and increment/decrement amount is larger than
"SpiralEndErr (#8075)", a program error (P70) will
occur.
Increment/
decrement
amount of
height
Range of
coordinate
command
(mm/inch)
(Decimal point
command is
possible.)
• If the sign of designated increment/decrement
amount is opposite from that of the movement
direction of height, a program error (P33) will occur.
• If the end point position obtained from the speed
and increment/decrement amount is larger than
"SpiralEndErr (#8075)", a program error (P70) will
occur.
G02.1/0G3.1
• Program error (P34) will occur if G02.1/G03.1 are
used during type 2.
