Alarm number ContentsFaulty location/corrective action
ER27 LADDER FUNC. PRM IS
OUT OF RANGE
Modify the sequence program. Change
the parameter number of the function
instruction to a value within the valid range.
An out–of–range parameter number is
specified with function instruction TMR,
TMRB, CTR, DIFU, or DIFD.
ER32 NO I/O DEVICE 1) Check that the I/O device is on.
2) Check that the I/O device was turned
on before the CNC was turned on.
3) Check the connection of the cable.
An I/O device such as the I/O Link, con-
nection unit, and Power Mate is not con-
nected.
ER33 I/O LINK ERROR Replace the master printed circuit board. The LSI of the I/O Link is defective.
ER34 I/O LINK ERROR (xx) 1) Check the connection of the cable
leading to a device in group xx.
2) Check that the I/O device was turned
on before the CNC.
3) Replace that device in group xx in
which the PMC control module is
installed.
In a slave in group xx, an error occurred
in communication with an I/O device.
ER35 TOO MUCH OUTPUT
DATA IN GROUP (xx)
Reduce the amount of output data in group
xx.
The amount of output data in I/O Link
group xx exceeds the limit (33 bytes).
The excess data is nullified.
ER36 TOO MUCH INPUT DATA
IN GROUP (xx)
Reduce the amount of input data in group
xx
The amount of input data in I/O Link
group xx exceeds the limit (33 bytes).
The excess data is nullified.
ER38 MAX SETTING OUTPUT
DATA OVER (xx)
Modify the total amount of output data in
each group to 128 bytes or less.
The I/O Link I/O area is insufficient.
(The allocation of any group after group
xx on the output side is nullified.)
ER39 MAX SETTING INPUT
DATA OVER (xx)
Modify the total amount of input data in
each group to 128 bytes or less.
The I/O Link I/O area is insufficient.
(The allocation of any group after group
xx on the input side is nullified.)
ER40 I/O LINK–II SETTING ER-
ROR (CHx)
Reconfigure the I/O Link–II. The I/O Link–II setting is invalid.
(CH1: Primary board, CH2: Secondary
board)
ER41 I/O LINK–II MODE ERROR
(CHx)
Reconfigure the I/O Link–II. The I/O Link–II mode setting is invalid.
(CH1: Primary board, CH2: Secondary
board)
ER42 I/O LINK–II STATION
NO.ERROR (CHx)
Reconfigure the I/O Link–II. The I/O Link–II station number setting is
invalid.
(CH1: Primary board, CH2: Secondary
board)
ER97 I/O LINK
(CHxyyGROUP)
1) Check whether the cables of I/O
devices in group yy are connected
properly.
2) Check the power to each I/O device.
3) Check the parameter setting of the I/O
link assignment data selection function.
The number of assigned I/O modules in
group yy differs from that of I/O devices
actually connected.
Note)This alarm can control how the
check function operates through
the use of keep relay K906.2.
K906.2 = 0: Connection check is
performed (initial value).
K906.2 = 1: Connection check is
not performed.
