PRM : An invalid parameter was found. Alarm No. 417 (invalid servo
parameter) is also issued.
STB : the serial pulse coder encountered a communication error.
The pulse coder, feedback cable, or feedback receiver circuit is defective.
Replace the pulse coder, feedback cable, or NC–side axis card.
CRC : The serial pulse coder encountered a communication error.
The pulse coder, feedback cable, or feedback receiver circuit is defective.
Replace the pulse coder, feedback cable, or NC–side axis card.
DTE : The serial pulse coder encountered a communication error.
The pulse coder, feedbak cable, or feedback receiver circuit is defective.
Replace the pulse coder, feedback cable, or NC–side axis card.
9) Servo alarms
Number Message Contents
401 SERVO ALARM: n–TH AXIS VRDY
OFF
The n–th axis (axis 1 to 8) servo amplifier READY signal (DRDY)
went off.
Refer to procedure of trouble shooting.
404 SERVO ALARM: n–TH AXIS VRDY
ON
Even though the READY signal (MCON) went off, the servo amplifier
READY signal (DRDY) is still on. Or, when the power was turned on,
DRDY went on even though MCON was off.
Check that the Power Mate i and servo amp are connected.
405 SERVO ALARM: (ZERO POINT
RETURN FAULT)
Position control system fault. Due to an NC or servo system fault in
the reference position return, there is the possibility that reference
position return could not be executed correctly. Try again from the
manual reference position return.
407 SERVO ALARM: EXCESS ERROR One of the following errors occurred during simple synchronous con-
trol operation:
1) The difference in position deviation between the synchronized axes
exceeds the value set in parameter No. 8314.
2) The maximum compensation amount at synchronization exceeds
the value set in parameter No. 8325.
409 SERVO ALARM: n AXIS TORQUE
ALM
Abnormal servo motor load has been detected.
410 SERVO ALARM: n–TH AXIS –
EXCESS ERROR
One of the following errors occurred:
1) The position deviation value when the n–th axis is stopped exceeds
the value set in parameter No. 1829.
2) During simple synchronous control, the maximum compensation
amount at synchronization exceeds the value set in parameter No.
8325.
This alarm is issued only in the slave axis.
411 SERVO ALARM: n–TH AXIS –
EXCESS ERROR
The position deviation value when the n–th axis (axis 1 to 8) moves is
larger than the set value.
The limit for each axis must be set in parameter No. 1828.
413 SERVO ALARM: n–th AXIS – LSI
OVERFLOW
The contents of the error register for the n–th axis (axis 1 to 8) ex-
ceeded 2
31
power. This error usually occurs as the result of an
improperly set parameters.
415 SERVO ALARM: n–TH AXIS –
EXCESS SHIFT
A speed higher than 511875 units/s was attempted to be set in the
n–th axis (axis 1 to 8). This error occurs as the result of improperly
set CMR.
