F.5 SV ALARM (ALARMS RELATED TO SERVO)
Number Message Contents
SV0008 EXCESS ERROR ( STOP ) Position deviation during a stop is larger than the value set
in parameter No. 1829.
Check the value of the position deviation error limit in
parameter No. 1829.
SV0009 EXCESS ERROR ( MOVING ) The position deviation during movement is larger than the
value set in parameter No. 1828.
SV0011 LSI OVERFLOW The position deviation counter overflowed.
SV0012 MOTION VALUE OVERFLOW A movement speed exceeding the limit was commanded.
The limit is as follows:
When acceleration/deceleration mode before pre-read
interpolation is enabled:
When fine acceleration/deceleration (FAD) and feed
forwarding are disabled in other than acceleration/
deceleration mode before pre-read interpolation:
32,767 pulses/msec (detection unit)
When fine acceleration/deceleration (FAD) is enabled in
other than acceleration/deceleration mode before pre-
read interpolation:
16,383 pulses/msec (detection unit)
When fine acceleration/deceleration (FAD) is disabled
but feed forwarding is enabled in other than acceleration/
deceleration mode before pre-read interpolation: 4095
pulses/msec (detection unit)
When parameter FFN (No. 1801#1) is set to 1, feed
forwarding can be enabled only in acceleration/
deceleration mode before pre-read interpolation. In this
state, the movement speed limit can be kept at 32,767
pulses/msec.
SV0013 IMPROPER V_READY OFF The speed control ready signal (VRDY) turned OFF even
though the position control ready signal (PRDY) was ON.
SV0014 IMPROPER V_READY ON The speed control ready signal (VRDY) turned ON even
though the position control ready signal (PRDY) was OFF.
SV0024 SYNC EXCESS ERROR ALARM 2 The synchronous error amount is greater than the value set
to parameter No. 1913 by the synchronize adjust function.
When synchronization alignment has not completed after
the power is turned ON, this error is judged by the value
obtained of multiplying the value of parameter No. 1913 by
the value of parameter No. 1910.
SV0025 V_READY ON (INITIALIZING ) During servo control, the speed control ready signal
(VRDY) turned ON even though it is supposed to be OFF.
SV0026 ILLEGAL AXIS ARRANGE The parameter for specifying the arrangement of the servo
axes is set incorrectly.
A minus value, duplicated value, or a value larger than the
number of controlled axes has been set to parameter No.
1023 (servo No. axis for each axis).
SV0027 ILL DGTL SERVO PARAMETER The setting of the digital servo parameter is illegal.
SV0030 EMERGENCY STOP Emergency stop occurred.
Whether or not this alarm is generated is determined by
ENR parameter No. 2001#0).
1: The control is reset by an emergency stop.
0: This alarm is generated without reset by an emergency
stop.
An emergency stop is canceled by resetting the control.
SV0055 ILLEGAL TANDEM AXIS The setting of parameter No. 1023 is illegal in tandem
control.
SV0056 ILLEGAL TANDEM PAIR The setting of parameter No. 1020 or TDM parameter No.
1817#6 is illegal in tandem control.
