M01

Droop cancel disabled

Details
Constant torque control droop cancel is commanded to the axis which is not in the constant/ proportional
torque control.
Constant torque control droop cancel is commanded to the axis in movement by automatic or manual op-
eration.
Remedy
Check the program.
Check the sequence program.
M01

Cmnd disabled in droop cancel

Details
The axis movement by automatic or manual operation is commanded to the axis which the constant torque con-
trol droop is being canceled.
Remedy
Check the program.
Check the sequence program.
M01

SP equivalent load factor over

Details
The equivalent load factor of the spindle motor has exceeded the set threshold that causes the excess warning.
Remedy
Change the operation pattern in a way that decreases the spindle motor load.
M01

Differential tap cmnd disabled

Details
Differential speed tap command has been given although any rotation command has not been input to the
basic spindle that is under spindle superimposition control.
Synchronous tap command has been given to the basic spindle that is under spindle superimposition con-
trol.
Remedy
Cancel the synchronous tapping cycle.
M01 Spd clamp in differential tap
Details
A tap cycle or synchronous tap cycle command given to the superimposed spindle has caused the spin-
dle's actual rotation speed to exceed the spindle clamp speed.
Remedy
Correct the spindle rotation speed in synchronous tap cycle.
M01 Constant surface spd disabled
Details
A constant surface speed control command has been given to the basic or superimposed spindle during
differential speed tapping under spindle superimposition control.
A differential speed tapping command has been issued while constant surface speed control is executed
on the basic or superimposed spindle that is under spindle superimposition control.
Remedy
Cancel the synchronous tap cycle or constant surface speed control.
