Alarm number Faulty location/corrective action Contents
ER22 NO PROGRAM Enter the sequence program again. The sequence program is empty.
ER27 LADDER FUNC. PRM IS
OUT OF RANGE
Correct the sequence program; change the
parameter number specified in a functional
instruction to a value that is within the
allowable range.
An out-of-range parameter number is
specified in the TMR, TMRB, CTR,
CTRB, DIFU, or DIFD functional
instruction.
ER28 NO OPTION(I/O LINK
CHx)
Contact us; specify the I/O Link point count
expansion option for the indicated channel.
The I/O Link point count expansion
option is not specified for CHx.
ER32 NO I/O DEVICE <1> Check whether the power of each I/O
device is on.
<2> Check whether the power of each I/O
device has been turned on before the
CNC.
<3> Check cable connections.
None of the I/O devices, such as the
I/O Link, connection unit, and Power
Mate, is connected.
ER33 I/O LINK ERROR
Or
ER33 I/O LINK ERROR(CHn)
Contact us; replace the faulty hardware. The LSI for the I/O Link is faulty.
ER34 I/O LINK ERROR(xx)
Or
ER34 I/O LINK ERROR(CHn xx)
<1> Check the cable connections to the
devices of group xx.
<2> Check whether the power of each I/O
device has been turned on before the
CNC.
<3> Replace any device of group xx in
which the PMC control module is
embedded.
An I/O device communication error
occurred on the slave side of group
xx.
ER35 TOO MUCH OUTPUT
DATA IN GROUP(xx)
Or
ER35 TOO MUCH OUTPUT
DATA IN GROUP(CHn xx)
Reduce the output data count of group xx. The output data count of I/O Link
group xx exceeds the upper limit (33
bytes). The superfluous data is
regarded as invalid.
ER36 TOO MUCH INPUT DATA
IN GROUP(xx)
Or
ER36 TOO MUCH INPUT DATA
IN GROUP(CHn xx)
Reduce the input data count of group xx. The input data count of I/O Link
group xx exceeds the upper limit (33
bytes). The superfluous data is
regarded as invalid.
ER37 TOO MUCH SLOT IN
BASE
Or
ER37 TOO MUCH SLOT IN
BASE(CHn)
Correct the slot number to a value of 10 or
less.
The slot number for the I/O Link
exceed the upper limit (10). The slot
number larger than 11 is regarded as
invalid.
ER38 MAX SETTING OUTPUT
DATA OVER(xx)
Or
ER38 MAX SETTING OUTPUT
DATA OVER(CHn xx)
Reduce the total amount of output data of
all groups to 128 bytes or less.
The I/O area for the I/O Link is
insufficient.
(The area allocated to the group xx
and later on the output side is
regarded as invalid.)
ER39 MAX SETTING INPUT
DATA OVER(xx)
Or
ER39 MAX SETTING INPUT
DATA OVER(CHn xx)
Reduce the total amount of input data of all
groups to 128 bytes or less.
The I/O area for the I/O Link is
insufficient.
(The area allocated to the group xx
and later on the input side is
regarded as invalid.)
ER48 STEP SEQUENCE TIME
OVER(xxH)
Remove the setting of exceeding setting
time on the STEP SEQUENCE TIME
MONITOR SETTING screen.
The activated condition of step
sequence exceeds the time limit,
which is set on the STEP
SEQUENCE TIME MONITOR
SETTING screen.
