B-63950EN/02 4.DESCRIPTION OF PARAMETERS
- 217 -
#7 #6 #5 #4 #3 #2 #1 #0
4900 FLRs
[Input type] Parameter input
[Data type] Bit spindle
# 0 FLRs When the spindle speed fluctuation detection function is used, the unit
of an allowable ratio (q) and fluctuation ratio (r) set by parameter No.
4911 and No. 4912 is:
0: 1%
1: 0.1%
4911
Allowable speed ratio (q) used to assume that the spindle has reached a
specified speed
[Input type] Parameter input
[Data type] Word spindle
[Unit of data] 1%, 0.1%
[Valid data range] 1 to 100, 1 to 1000
When the spindle speed fluctuation detection function is used, set an
allowable speed ratio (q) used to assume that the spindle has reached a
specified speed.
NOTE
The unit of data is determined by bit 0 (FLR) of
parameter No. 4900.
4912
Spindle variation ratio (r) for not issuing a spindle speed fluctuation
detection alarm
[Input type] Parameter input
[Data type] Word spindle
[Unit of data] 1%, 0.1%
[Valid data range] 1 to 100, 1 to 1000
When the spindle speed fluctuation detection function is used, set a
spindle fluctuation ratio (r) for not issuing an alarm.
NOTE
The unit of data is determined by bit 0 (FLR) of
parameter No. 4900.
