Synchronized Tapping (G88) on Mori Seiki SL-25Y

[WNP]

Hi
This is my first post if I did something wrong I'm sorry.

My problem is side tapping (synchronized tapping cycle G88) it stall.
I'm using 4 axis lathe Mori Seiki SL-25Y controlled by MF-T6 (or equivalent to Fanuc 16-TA)
Here is my code:

N15(DRILL2 2)
M69
G54
G98 G18 M45
G0 G28 H0.
M68
T1111
G4 P2000
M69
G0 C0.
M68
G0 Z-2.5
X60.
G0 X50.
G97 S1200 M329
G99
G88 X35. R0. P1000 F0.5
G98 G80
G0 X60.

M05
G28 U0.
G28 W0.
M30

I'm trying to tap M2x0.4 to predrill hole 1.6 mm. Program stall at G88 Block no any error but
my rotary tool spin very slow.

I am confused. What did I do wrong? or my machine doesn't support synchronized tapping (rigid tapping)

Any advice will be appreciated.

I have a similar machine with a Fanuc 16TA control. I am just starting out with testing rigid tapping, what I found out thus far is. G88 doesn't work on my machine, when I use G84 with IPM and a S200 M329 before the G84 seems to work but I haven't tested it on a part only air tested it. Check parameter 5200 & 5210 to see what the rigid tapping mode M code should be. Hope this helps.
