PRM
#3 #2 #1 #0
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 servo amplifier.
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 servo amplifier.
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 servo amplifier
5) Servo alarms
For the following alarms, also refer to the relevant manuals on the servo
motor α/β series:
Number Message Contents
401 SERVO ALARM: nTH AXIS VRDY
OFF
The nth axis (axis 1 to 8) servo amplifier READY signal (DRDY) went
off.
Check the servo amplifier status.
402 SERVO ALARM: SV CARD NOT EX-
IST
Necessary cards for at least four axes for the M series, or at least two
axes for the Taxis system or loader, are not installed. Install the correct
axis cards.
403 SERVO ALARM: CARD/SOFT MIS-
MATCH
The axis cards and servo software do not match. Use a valid combina-
tion of axis cards and servo software.
404 SERVO ALARM: nTH 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 control
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: nTH AXIS
EXCESS ERROR
One of the following errors occurred:
1) The position deviation value when the nth 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.
