16715 Channel %1 block %2 axis %3 spindle not in standstill
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Spindle number
Definitions: In the applied function (G74, reference point approach), the spindle must be stationary.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Program M5 or SPOS/SPOSA in front of the defective block in the part program.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16720 Channel %1 block %2 axis %3 thread lead is zero
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: No lead was programmed in a thread block with G33 (thread with constant lead) or G331 (rigid
tapping).
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: The thread lead must be programmed for the specified geometry axis under the associated
interpolation parameters.
X -> I
Y -> J
Z -> K
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16730 Channel %1 block %2 axis %3 wrong parameter
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: In G33 (tapping with constant lead) the lead parameter was not assigned to the axis that determines
the velocity.
For longitudinal and face threads, the thread lead for the specified geometry axis must be
programmed under the associated interpolation parameter.
X -> I
Y -> J
Z -> K
For taper threads, the address I, J, K depends on the axis with the longer path (thread length). A 2nd
lead for the other axis is, however, not specified.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Assign lead parameters to the axis that determines the velocity.
Program Clear alarm with NC START or RESET key and continue the program.
