2. FUNCTION EXPLANATION
FANUC AC SPINDLE MOTOR a series
95
Gear 2 5758 5762
Gear 3 5759 5764
(d) Series 15i
i) Acc/Dec type
5605 #1
0 : Exponential type
1 : Linear type Acc/Dec (Standard setting)
ii) Set Acc/Dec the time constant of the rigid tapping mode.
D The time constant is a fixed value if bit 2 of parameter No.
5605 = 0.
Acc/Dec time constant 5751
Spindle speed 5757
D When bit 2 of parameter No.5605 is set to 1, one of the four
acceleration/deceleration time constants is selected, depending
on the spindle speed.
Spindle speed Acc/Dec time constant
Gear 1 5886 5884
Gear 2 5889 5887
Gear 3 5892 5890
Gear 4 –– 5893
(e) Series 16i/16
i) Each parameter can be set for each gear and is selected
according to the gear selection signal.
By setting the following parameter, the different time
constant between the cutting in and cutting out (extracting)
becomes available.
5201 #2
0 : The same time constant between cutting in and out.
(NO. 5261 to 5264)
1 : The different time constant between cutting in and out.
Cutting in : NO. 5261 to 5264
Cutting out: NO. 5271 to 5274
