1. List of Alarms
1.1 Operation Alarms
I - 3
Error No. Details Remedy
0050
Chopping axis zero point return
incomplete
The chopping axis has not completed
zero point return before entering the
chopping mode.
All axes interlock will be applied.
• Reset or turn the chopping signal OFF,
and then carry out zero point return.
0051 Synchronization error too large
The synchronization error of the master
and slave axes exceeded the allowable
value under synchronous control.
A deviation exceeding the synchroni-
zation error limit value was found with
the synchronization deviation detection.
• Select the correction mode and move
one of the axes in the direction in which
the errors are reduced.
• Increase the allowable value or reset it
to 0 (check disabled).
• When using simple C-axis synchronous
control, set the contents of the R435
register to 0.
• Check the parameter (#2024 synerr).
0101 NOT OP MODE (Not operation mode) • Check for a broken wire in the input
mode signal wire.
• Check for trouble in the mode selector
switch.
• Check the sequence program.
0102
OVERRIDE ZERO (Override zero)
“The cutting feed override” switch on the
machine operation panel is set to zero.
• Set "the cutting feed override" switch to
a value other than zero to release the
error.
• If "the cutting feed override" switch is set
to a value other than zero‚ check for a
short circuit in the signal wire.
• Check the sequence program.
0103
EX F SPD ZRO (External feed speed
zero)
“The manual feed speed” switch on the
machine operation panel is set to zero
when the machine is in the jog mode or
automatic dry run mode.
The "Manual feedrate B speed" is set to
zero during the jog mode when manual
feedrate B is valid.
The "each axis manual feedrate B
speed" is set to zero during the jog mode
when each axis manual feedrate B is
valid.
• Set "the manual feed speed" switch to a
value other than zero to release the
error.
• If “the manual feed speed” switch is set
to a value other than zero‚ check for a
short circuit in the signal wire.
• Check the sequence program.
0104
F1 SPD ZRO (F1-digit speed zero)
The F1-digit feedrate is set to zero when
the F1-digit feed command is being
executed.
• Set the F1-digit feedrate on the setup
parameter screen.
