Before the tapping axis is changed, the canned cycle must be canceled. If the
tapping axis is changed in rigid mode, P/S alarm (No.206) is issued.
Specifying a rotation speed exceeding the maximum speed for the gear used
causes P/S alarm (No.200).
Distribution amount for the spindle
[For an analog spindle control circuit]
Upon specifying a speed command requiring more than 4096 pulses, in
detection units, within 8 ms, a P/S alarm (No.202) is issued.
[For a serial spindle]
Upon specifying a speed command requiring more than 32767 pulses, in
detection units, within 8ms, a P/S alarm (No.202) is issued.
If a value exceeding the upper limit of cutting feedrate is specified, P/S alarm
(No.011) is issued.
Unit of F command
Metric input Inch input Remarks
G94 1mm/min 0.01inch/min Decimal point programming allowed
G95 0.01mm/rev 0.0001mm/rev Decimal point programming allowed
M29 (M-code for rigid tapping mode specification)
If an S command and axis movement are specified between M29 and G84,
P/S alarm (No.203) is issued.
If M29 is specified in a tapping cycle, P/S alarm (No.204) is issued.
Specify P and Q in a block that performs drilling. If they are specified in a
block that does not perform drilling, they are not stored as modal data.
When Q is not specified, the peck rigid-tapping, which only an
over-torque signal is concerned, is specified. If an over-torque signal is
not detected, the action of small-hole peck rigid-tapping is as same as it of
normal rigid tapping.
When Q0 is specified, the small-hole peck rigid-tapping is not performed.
