B–63010EN/02
232
NOTE
1 This parameter is valid if bit 4 (SSS) of parameter No. 3704
is set to 1.
2 Multiple slave axes cannot simultaneously enter the
synchronization mode for a single master axis.
3 After this parameter is set, the power must be turned off then
back on for the setting to become effective.
4 Parameter No. 4834 is valid only for Series 16i.

FLR When the spindle speed fluctuation detection function is used, the rates of
allowance (q) and fluctuation (r) those are set in parameter No.4911 and
No.4912, respectively are set in steps of:
0 : 1%
1 : 0.1%

Set the ratio (q) of the spindle speed which is assumed to be the specified
spindle speed in the spindle speed fluctuation detection function.
Let the commanded speed be Sc. When the actual spindle speed reaches
between (Sc–Sq) and (Sc + Sq), it is assumed to be the commanded speed.
The spindle speed fluctuation detection starts.
