Description

Although neither *ESP (emergency stop signal; there
are two types of signals including the input signal and
PSM contact signal) nor MRDY (machine ready
signal) is input, SFR (forward rotation signal)/SRF
(reverse rotation signal)/ORCM (orientation
command) is input.

Check the *ESP and MRDY sequence. For MRDY,
pay attention to the parameter setting regarding the
use of the MRDY signal (parameter No. 4001#0).

The parameter settings are such that a position
sensor is not used (position control not performed)
(bits 3, 2, 1, 0 of parameter No. 4002 = 0, 0, 0, 0), but
a Cs contour control command is input.
In this case, the motor is not excited.

Check the parameter settings.

The parameter settings are such that a position
sensor is not used (position control not performed)
(bits 3, 2, 1, 0 of parameter No.4002 = 0, 0, 0, ), but
a servo mode (rigid tapping, spindle positioning, etc.)
or spindle synchronization command is input.
In this case, the motor is not excited.

Check the parameter settings.

The orientation function option parameter is not
specified, but ORCM (orientation command) is
input.

Check the orientation function parameter settings.

The output switching control function option
parameter is not specified, but low-speed
characteristic winding is selected (RCH = 1).

Check the output switching control function
parameter settings and the power line state check
signal (RCH).

A Cs contour control command is input, but SFR
(clockwise rotation command)/SRV
(counterclockwise rotation command) is not input.

Faulty location and remedy

Description

A servo mode (rigid tapping, spindle positioning,
etc.) command is input, but another mode (Cs
contour control, spindle synchronization, or
orientation) is specified.

Do not switch to another mode during a servo
mode command.
Before moving to another mode, cancel the servo
mode command.

A spindle synchronization command is input, but
another mode (Cs contour control, servo mode, or
orientation) is specified.

Do not switch to another mode during a spindle
synchronization command.
Before moving to another mode, cancel the
spindle synchronization command.

Both SFR (clockwise rotation command) and SRV
(counterclockwise rotation command) are input at
the same time.

Issue either of them.

The speed detector parameter settings (bits 2, 1,
and 0 of parameter No. 4011) are not valid.

There is no corresponding speed detector.

Check the parameter settings.

The parameter settings are such that a position
sensor is not used (position control not performed
(bits 3, 2, 1, and 0 of parameter No. 4002), but
position coder system orientation is issued.

Check the parameter settings and the input signal.

If index is performed continuously in position coder
system orientation, an incremental operation is
performed first (INCMD = 1), then an absolute
position command (INCMD = 0) is input.

Check INCMD (incremental command).
If an absolute position command is to follow, be
sure to perform absolute position command
orientation first.

The parameter settings are such that the
shortest-time orientation function is used (bit 6 of
parameter No. 4018 = 0, Nos. 4320 to 4323

≠

0).

In the

series spindle amplifier, the shortest-time

orientation function cannot be used. Use
normal-system orientation.

The hardware configuration is such that the spindle
FAD function cannot be used.
In this case, the motor is not activated.

Check the CNC model.

The hardware configuration is such that the spindle
EGB function cannot be used.
In this case, the motor is not activated.

Check the CNC model.

Both the spindle FAD function and the spindle EGB
function are enabled.
In this case, the motor is not activated.

The two functions cannot be used at the same
time. Enable either function only.

The submodule SM (SSM) is faulty or the
connection between SPM and SSM is in error.

DS0017

SERIAL DCL:REF-POS ESTABLISH
ERR

The travel amount at the FL speed at establishment of the
origin exceeded the setting of parameter No. 14010.

DS0018

SERIAL DCL:MISMATCH(SSYNC CTRL)

Of the master and slave axes for feed axis synchronous
control, one axis is a linear scale with the origin and the other
is not a linear scale with the origin. In such a configuration,
the feed axis synchronous control selection signal
(SYNC<Gn138> or SYNCJ <Gn140>) needs to be set to 0 to
establish the origin.

DS0020

REFERENCE RETURN INCOMPLETE

An attempt was made to perform an automatic return to the
reference position on the perpendicular axis before the
completion of a return to the reference position on the
angular axis.
However, this attempt failed because a manual return to the
reference position during angular axis control or an automatic
return to the reference position after power-up was not
commanded. First, return to the reference position on the
angular axis, then return to the reference position on the
perpendicular axis.

DS0022

DUAL CHECK SAFETY IS NOT
WORKED

Bit 6 (DCE) of parameter No. 1902 has set the Dual Check
Safety function to be disabled.

to the machining restart position at the dry run speed.

DS0025

G60 CANNOT BE EXECUTED

The state of a mirror image is different between the time
when look-ahead of a block for unidirectional positioning was
performed and the time when execution of the block was
started, so unidirectional positioning cannot be performed.
Modify the program.

DS0026

MISMATCH OF ANGULAR AXIS(D.C.S)

On angular axis control, one of the angular/perpendicular
axes is the scale with ref-pos, and the other of them is not
the scale with ref-pos. Such system is not admired.

DS0027

MISMATCH OF SYNCHRONOUS
AXIS(D.C.S)

Master/slave axes of axis synchronous control, one of them
is the linear scale with distance-coded reference marks, and
the other of them is not the linear scale with distance-coded
reference marks.
Please establish reference position with the input signal
SYNCn<G138>, SYNCJn<G140> or parameter setting to 0.

DS0029

UNAVAILABLE ROT AXIS MOVE IN TPC

In tool posture control, the rotation axis fell outside the set
operation range (parameters No. 19741 to No. 19744).
Review the machine configuration and command.

DS0030

TOOL DIRC CMP IMPOSSIBLE

When tool center point control is performed in the angular
surface machining command mode or workpiece placement
error compensation is performed in a 5-axis cutting machine,
if settings are made to make compensation in the tool
direction (bit 0 (RCM) of parameter No. 11200 is 1), the
position of the rotation axis could not be obtained.
