Number ContentsMessage
411 SERVO ALARM: nTH AXIS
EXCESS ERROR
The position deviation value when the nth 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: nth AXIS LSI
OVERFLOW
The contents of the error register for the nth axis (axis 1 to 8) exceeded
"2
31
power. This error usually occurs as the result of an improperly set
parameters.
415 SERVO ALARM: nTH AXIS
EXCESS SHIFT
A speed higher than 511875 units/s was attempted to be set in the nth
axis (axis 1 to 8). This error occurs as the result of improperly set CMR.
417 SERVO ALARM: nTH AXIS
PARAMETER INCORRECT
This alarm occurs when the nth axis (axis 1 to 8) is in one of the
conditions listed below.
Check the following parameters. See Chapter 7.
1) The value set in Parameter No. 2020 (motor form) is out of the
specified limit.
2) A proper value (111 or 111) is not set in parameter No.2022 (motor
revolution direction).
3) Illegal data (a value below 0, etc.) was set in parameter No. 2023
(number of speed feedback pulses per motor revolution).
4) Illegal data (a value below 0, etc.) was set in parameter No. 2024
(number of position feedback pulses per motor revolution).
5) Parameters No. 2084 and No. 2085 (flexible field gear rate) have not
been set.
6) A value outside the limit of {1 to the number of control axes} or a
noncontinuous value (Parameter 1023 (servo axis number)
contains a value out of the range from 1 to the number of axes, or
an isolated value (for example, 4 not prceded by 3).was set in
parameter No. 1023 (servo axisnumber).
7) There is a parameter setting error in torque control of PMC axis
control. (The torque constant parameter is set to 0.)
420 SERVO ALARM: n AXIS SYNC
TORQUE
(M series)
During simple synchronous control, the difference between the torque
commands for the master and slave axes exceeded the value set in
parameter No. 2031.
421 SERVO ALARM: n AXIS EXCESS
ER (D)
The difference between the errors in the semiclosed loop and closed
loop has become excessive during dual position feedback. Check the
values of the dual position conversion coefficients in parameters No.
2078 and 2079.
422 SERVO ALARM: n AXIS In torque control of PMC axis control, a specified allowable speed has
been exceeded.
423 SERVO ALARM: n AXIS In torque control of PMC axis control, the parameterset allowable
cumulative travel distance has been exceeded.
430 n AXIS : SV. MOTOR OVERHEAT A servo motor overheat occurred.
431 n AXIS : CNV. OVERLOAD A servo amplifier overheat occured.
432 n AXIS : CNV. LOWVOLT
CON./POWFAULT
A lowvoltage alarm is issued in the converter control section.
433 n AXIS : CNV. LOW VOLT DC LINK A lowvoltage alarm is issued in the converter DC link section.
434 n AXIS : INV. LOW VOLT CONTROL A lowvoltage alarm is issued in the inverter control section.
435 n AXIS : INV. LOW VOLT DC LINK A lowvoltage alarm is issued in the inverter DC link section.
436 n AXIS : SOFTTHERMAL (OVC) An overcurrent alarm is issued.
437 n AXIS : CNV. OVERCURRENT
POWER
An abnormalcurrent alarm is issued in the converter.
438 n AXIS : INV. ABNORMAL
CURRENT
An abnormalcurrent alarm is issued in the inverter.
439 n AXIS : CNV. OVERVOLT POWER An overvoltage alarm is issued.
