Operation Errors (M)
I - 8
M01 Tool length compensation amt 0 0252
Details
The tool length compensation amount for performing the R-Navi indexing type 2 is 0.
Remedy
- Set the tool length compensation amount for performing the indexing type 2 to a value other
than 0.
M01 Feat coord ill w/ multi-handle 0253
Details
Manual feed feature coordinate system was selected while two or more handles were ON.
Remedy
- Manual feed on a feature coordinate system is disabled while two or more handles are en-
abled (*).
- Press [Manual coord] and select the machine coordinate system.
- Reduce the number of enabled handles (*) to one.
(*) An enabled handle means the handle for which “Nth handle valid” signal (HSnS) is ON.
M01 Auto backlash adjust illegal 0270
Details
- A measurement condition adjustment or backlash adjustment was attempted to an axis with
which automatic backlash adjustment is impossible.
- A measurement condition adjustment or backlash adjustment was attempted even though
all the axes had not reached the 1st reference position.
- The operation mode is other than memory mode.
- The slave axis of synchronous control is selected as adjustment axis.
- An attempt has been made to start an adjustment by cycle start.
Remedy
- Check the adjustment axis.
- Start the adjustment after all the axes return to the 1st reference position.
- Check the operation mode.
- Select the master axis of synchronous control as adjustment axis when adjusting the slave
axis.
- Start the adjustment by automatic backlash adjustment start signal.
M01 Operating auto backlash adjust 0271
Details
An illegal operation was attempted during measurement condition adjustment or backlash ad-
justment.
Remedy
- Continue the operation after canceling the measurement condition adjustment and backlash
adjustment.
M01 APLC password mismatch 0280
Details
The APLC authentication password is inconsistent.
Remedy
- Contact the machine tool builder.
M01 High-cycle sampling disabled 0290
Details
- The drive unit's hardware or software does not conform to the high-cycle sampling mode.
- High-cycle data are not used even when high-cycle sampling has been set.
- High-cycle sampling was attempted while the axis targeted for high-cycle sampling was
moving.
- High-cycle sampling was attempted during speed monitor mode.
- High-cycle sampling was attempted while any of the following operations is being executed:
Dog-type zero point return, absolute position setting, synchronous tapping, spindle synchro-
nization, hobbing, tool spindle synchronization IC.
Remedy
- The software or hardware does not conform to the function. Contact service center.
- Set data for high-cycle sampling.
- Execute high-cycle sampling after stopping the axis targeted for high-cycle sampling.
- Execute high-cycle sampling after cancelling the speed monitor mode.
- Execute high-cycle sampling after stopping the currently executed functions.
M01 N/A during high-cycle sampling 0291
Details
- An attempt to activate "Speed monitor mode" was made during the high-cycle sampling
mode.
- An attempt to change the gear signal was made during the high-cycle sampling mode.
- An attempt to execute spindle orientation was made during the high-cycle sampling mode.
- Spindle detach was attempted during the high-cycle sampling mode.
- Any of the following operations was attempted during the high-cycle sampling mode: Dog-
type zero point return, absolute position setting, spindle/C axis changeover, synchronous
tapping, spindle synchronization, hobbing, or tool spindle synchronization IC.
Remedy
- Change the speed monitor mode signal back, finish high-cycle sampling, and then select the
speed monitor mode.
- Change the gear signal back, finish high-cycle sampling, and then change the gear.
- Change the spindle orientation signal back, finish high-cycle sampling, and then execute ori-
entation.
- Change the spindle detach signal back, finish high-cycle sampling, and then carry out spin-
dle detachment.
- Execute the operation after terminating high-cycle sampling.
M01 Illegal movement command during superimposition 1003
Details
- A machine command was issued to the superimposing axis.
- Reference position return was attempted on the superimposing axis.
- Skip command was issued to the master or superimposing axis.
- Dog-type reference position return was attempted on the master axis.
Remedy
- Correct the program.
