Appendix 7. Explanation of Alarms
Appendix 7.1 Operation Errors (M)
M01 No spindle select signal 0053
Details
Synchronous tapping command was issued when the "spindle selection" signals for all
spindles were OFF in the multiple-spindle control II.
Remedy
- Turn ON the "spindle selection" signal for the tapping spindle before performing the
synchronous tapping command.
M01 No spindle serial connection 0054
Details
Synchronous tapping command was issued in the multiple-spindle control II, while the
spindle with the "spindle selection" signal ON was not serially connected.
Remedy
- Make sure the "spindle selection" signal for the spindle is ON.
- Consider the machine construction when issuing the command.
M01 Spindle fwd/rvs run para err 0055
Details
Asynchronous tapping command was issued when M code of the spindle forward/reverse
run command, set by "#3028 sprcmm", was one of the followings in the multiple-spindle
control II.
- M0, M1, M2, M30, M98, M99, or M198
- M code No. that commands to enable/disable the "macro interrupt" signal
Remedy
- Correct the "#3028 sprcmm (Tap cycle spindle forward run/reverse run M command)"
setting.
M01 Tap pitch/thread number error 0056
Details
The command for the pitch or the number of threads is not correct in the synchronous
tapping command of the multiple-spindle control II.
The pitch is too small for the spindle rotation speed.
Thread number is too large for the spindle rotation speed.
Remedy
- Correct the pitch, number of threads or rotation speed of the tapping spindle.
M01 Wait for tap retract 0057
Details
The axis travel command is interlocked in the part system where the "Tap retract possible"
signal is ON.
Remedy
- If tap retract is necessary, perform it before issuing an axis travel command.
- If tap retract is not necessary, cancel the tap retract enabled state.
M01 Handle ratio too large 0060
Details
- The handle ratio is too large for the handle feed clamp speed.
(The handle feed clamp speed changes according to the rapid traverse rate, external
feedrate, maximum speed outside the soft limit range and etc. (or external deceleration
speed when external deceleration is valid))
Remedy
- Change the settings of the handle feed clamp speed or the handle ratio.
