4913
Spindle speed fluctuation width (i) for not issuing a spindle speed
fluctuation detection alarm
[Input type] Parameter input
[Data type] 2-word spindle
[Unit of data] min
-1
[Valid data range] 0 to 99999
When the spindle speed fluctuation detection function is used, set an
allowable fluctuation width (i) for not issuing an alarm.
4914
Time (p) from the change of a specified speed until spindle speed fluctuation
detection is started
[Input type] Parameter input
[Data type] 2-word spindle
[Unit of data] msec
[Valid data range] 0 to 99999
When the spindle speed fluctuation detection function is used, set a
time (p) from the change of a specified speed until spindle speed
fluctuation detection is started. In other words, spindle speed
fluctuation detection is not performed until a set time has elapsed after
a specified speed is changed. However, when the actual spindle
speed is assumed to have reached a specified value within a set time
(p), spindle speed fluctuation detection is started.

[Data type] Bit spindle
# 0 IORs Resetting the system in the spindle positioning mode
0: Does not releases the mode.
1: Releases the mode
# 1 IDMs The direction of spindle positioning (half-fixed angle positioning
based on M codes) is:
0: Plus direction.
1: Minus direction.
# 2 ISZs When an M code for switching to the spindle positioning mode is
specified for spindle positioning:
0: The spindle is switched to the spindle positioning mode, and
spindle orientation operation is performed.
1: Only the switching of the spindle to the spindle positioning mode
is performed. (Spindle orientation operation is not performed.)
# 5 TRVs The rotation direction for spindle positioning is:
0: Same as the specified sign.
1: Opposite to the specified sign.
