Parameter
12255 Maximum servo motor speed
[Input type] Parameter input
[Data type] Real axis
[Unit of data] mm/min, inch/min, degree/min (machine unit)
[Minimum unit of data] Depend on the increment system of the applied axis
[Valid data range] Refer to the standard parameter setting table (C)
(When the increment system is IS-B, 0.0 to +240000.0)
This parameter sets a maximum servo motor speed. When the value
set in this parameter is exceeded, the servo motor stops with the alarm
(DS0004). When 0 is set in this parameter, the specification of a
maximum allowable value (999000 for IS-B) is assumed.
12256 Maximum servo motor acceleration rate
[Input type] Parameter input
[Data type] Real axis
[Unit of data] mm/sec/sec, inch/sec/sec, degree/sec/sec (machine unit)
[Minimum unit of data] Depend on the increment system of the applied axis
[Valid data range] Refer to the standard parameter setting table (D)
(When the machine system is metric system, 0.0 to +100000.0. When
the machine system is inch system, machine, 0.0 to +10000.0)
This parameter sets a maximum servo motor acceleration rate. When
the value set in this parameter is exceeded, the servo motor stops with
the alarm (DS0005). When 0 is set in this parameter, alarm check is
not performed.
Alarm and message
The machine is decelerated and stopped when a DS alarm is issued or
is immediately stopped when an IE alarm is issued to prevent any
malfunction.
Check the block in which the machine is stopped. If you cannot find
the cause, contact FANUC without releasing the alarm state.
Number Message Description
DS0004 EXCESS MAXIMUM FEEDRATE The malfunction prevention function detected the command
in which a value exceeding the maximum speed was
specified.
DS0005 EXCESS MAXIMUM ACCELERATION The malfunction prevention function detected the command
in which a value exceeding the maximum acceleration was
specified.
DS0006 ILLEGAL EXECUTION SEQUENCE The malfunction prevention function detected an illegal
execution sequence.
DS0007 ILLEGAL EXECUTION SEQUENCE The malfunction prevention function detected an illegal
execution sequence.
DS0008 ILLEGAL EXECUTION SEQUENCE The malfunction prevention function detected an illegal
execution sequence.
DS0009 ILLEGAL EXECUTION SEQUENCE The malfunction prevention function detected an illegal
execution sequence.
