ALARMS
If you have a Y03
Alarm, there will be an axis number displayed to the right of the alarm. This
alarm means that the NC believes that axis is not connected to the system. First
check that all of the servo amplifiers are connected and that they are all
being supplied with AC voltage normally labeled R and S. Also check for the
presence of the DC Link on all three axes. Make sure the Serial Buss is daisy
chained to all of the amps and to the spindle. Check all of the rotary selector
switches on the amps and the spindle to be sure they are in the correct
position. The description of this alarm in the manual indicates a hardware
fault as the likely culprit but in most cases you will probably find a
parameter set wrong so if you have a copy of the parameters you might want to
go ahead and reload them.
Alarm Y06 is
basically the same deal and will always be a parameter If you have the alarm
Y03 AMP UNEQUIPPED XYZA and alarm EMERGENCY STOP LIN, there is a good chance
the CPU is not communicating with the amplifiers. In this case, the likely
suspects are the serial cables, the terminator plug or the communication board
QX721 or QX722. The control will have one of these boards are the other. It is
a small board which is mounted piggyback on the CPU board. A good test for this
case is to replace the cable that goes from the CPU to the first amplifier. In
the field this may be difficult. You can take a cable from between two of the
amps is long enough and connect it to port CN1A of the first amp and to the
CPU. Place the terminator on port CN1B of this amp. If the cable was bad, when
you power up this time the alarm should say something different depending on
which amp you are connected to. For example, Y03 AMP UNEQUIPPED YZA or XZA. In
this case, replacing the cable should solve the problem. The communication
boards do go bad sometimes so don't be afraid to replace it if you cannot
effect a change by moving cables around. Anytime you have the Y03 alarm along
with other alarms there is a way to bypass the alarm so you can work on the
other problems. Remove the cable from CSH21 on the CPU and insert the
terminator plug into the port. Go to the Machine Base Parameter NOAMP and make
it a 1. This will tell the NC that no amps are installed and the alarm will go
away.
Also for the Y03 AMP
UNEQUIPPED ALARM, if you get this after replacing or adding an amplifier, make
sure the DIP switches on the amps are set correctly to identify the axes to the
NC.
Often times you will
have an alarm such as S52 Servo Warning 00E6 X. This does not always mean there
is a problem with the X axis. Sometimes there will be a problem communicating
with all of the servos but if X is the first in the string, the NC may issue
this alarm. If you have an alarm like this in conjunction with an EMG Emergency
PLC alarm the problem may have nothing to do with the servos at all. In this
case the problem could be with something such as the Keypad Interface Card in
the pendant. In particular, if the four pin cable that goes to J4 on the keypad
interface card is removed, damaged, etc. this alarm will definitely occur. This
cable uses two of the four wires. They connect to 24vdc on the external power
supply.
MDS-A-SPJA-75RT
AL-30 on this
amplifier is a regenerative alarm. It can occur if the AC Line exceeds 260
volts or if the regenerative braking system (resistor) fails. Experience has
shown that it usually means that the amplifier is bad. AL-24 is a Ground Fault
alarm, it normally occurs if a motor is grounded or one of the AC power leads
is accidentally swapped with a motor lead.
The following is a
nearly complete list of Mitsubishi Alarms as displayed on the drives. Depending
on the specific drive, the LED display may show an A or an AL along with the
number but the meaning is the same. Some alarm numbers shown here may appear on
other Mitsubishi drives and their meanings may be other than indicated here.
Also, an effort is made here to distinguish Servo alarms from Spindle alarms by
entering SV or SP after the description. Due to the various uses and
configurations of drives as well as typing errors etc., you have to use your
best judgment when applying these alarms to your situation.

refer to the spindle alarm section. These alarms always require that the drive

When AL-25 is
displayed on an amplifier, it means the Absolute Position has been erased.
Normally, if you turn the power off then back on it will go away. Sometimes it
helps to hold the NC power on button while the control is powering up. On some
machines it will be necessary to reset the axes zero positions once the alarm
is gone.
Alarm AL-A1 is normal
sometimes when you swap servo amplifiers. It means that when the amplifier
powers up it sees an absolute position other than what it expects to see. In
other words the amplifier stores the position of the axis relative to the
marker pulses of the encoder and when it powers up and compares this to the
position of the pulse coder and sees a difference, the alarm is generated. This
is a fairly low priority alarm and will not be displayed if other pulse coder
alarms are present such as AL-16 which is a communication problem between the
pulse coder and amp.
For alarm E51 FILE
OPEN ERROR, check how much memory is available. In some cases the memory may
get reset to 0 for the amount Free and the amount Used. This is more or less
common if you change an Option Parameter, especially the memory size parameter
(prosiz). To resolve the problem, change fix_p to 1 and Format the control.
P461 FILE I/O ERROR
will normally result from not re-loading the Fixed Cycles after formatting the
control.
If alarm S52 M01 0102
is issued when taking a cut, check Machine Servo Parameters SV021 and SV022.
SV022 specifies the current detection level of overload 1 (OL1) with respect to
the stall rating (%). Setting range is 1-500%. Parameter SV021 specifies a time
constant for detection of of overload 1 (OL1). The setting range is 1-1800
seconds. What all this means is that if you have an axis which the axis faults
or alarms during a cut parameter SV022 tells the control what level of current
or motor load is allowable, SV021 tells the control how long the motor is
allowed to pull this amount of current.
The alarms on the
M300 control are almost identical to the M500.
Alarm E10 MEMORY OVER
means that a value was set in the parameter PROSIZ that exceeds the hardware
memory capacity of the control.
You cannot put a
negative value in the Grid Shift parameter (G28sft). If you try to the control
will issue the E02 DATA OVER alarm.
Regardless of which
alarm is displayed on the CRT, the important thing is the four numbers at the
end of the line (i.e. 006C), this tells the story of what the control thinks is
wrong.
Not every manual
lists or explains the S04 servo alarms, below is a partial list.

The CPU of MDS-B-HR connected with the machine end does not operate properly.
When adjusting for
spindle orientation position shift (OPST) on an M520 or M530 control, it is
sometimes not necessary to orient the spindle after adjustment to check the
shift amount. If the machine uses a magsensor for orientation, when you change
the parameter and press INPUT, the spindle will move the shift amount
difference.
When the EDIT LOCK
(hardware) of a machine with an M520 control is switched on and off, the Main
Program display will switch from ABC, etc. to blank. Parameter will switch from
ON to OFF.
Typically, if the
spindle motor is phased wrong on a machine with a Mitsubishi drive the motor
will run slower than commanded, may move jerkedly, may run one direction when
M03 commanded the other direction when M03 commanded again, eventually will
generate alarm S03 PR 23.
