Description
1410 Integer –1 Forward rotation M code for the second spindle
(for back machining)
1411 Integer –1 Reverse rotation M code for the second spindle
(for back machining)
1412 Integer 5 Spindle stop M code for the second spindle
(for back machining)
1413 Integer –1 C–axis connection M code for the second spindle
(for back machining)
1414 Integer –1 C–axis disconnection M code for the second spindle
(for back machining)
1415 Integer 68 C–axis clamping M code for the second spindle
(for back machining)
1416 Integer 69 C–axis unclamping M code for the second spindle
(for back machining)
D An M code for which the corresponding parameter is set to –1
is not output.
D During the creation of NC data, whether the M code for the first
spindle or that for the second spindle will be output is
determined from the spindle number (SN), defined using the
tool data screen for machining definition.
D Three–digit integers can be used for the above M codes.
D Conventionally, the forward/reverse rotation M codes for the
second spindle have been specified using MTF1142 and
MTF1143. These MTF parameters can, however, specify only
two–digit integers. To enable the specification of three–digit
integers, MTF1410 and MTF1411 have been added. MTF1142
and MTF1143 can no longer be used.
