2.3.7 Details of Related Parameters
This subsection details the serial spindle parameters (in the four
thousands for 16i, and in the four thousands for 30i, and in the three
thousands for 15i) among the parameters related to rigid tapping. For
details of other parameters, refer to the Connection Manual (Function)
of each CNC.
(a) For Series 16i/18i/21i
“FANUC Series 16i/18i/21i-MODEL B
CONNECTION MANUAL (FUNCTION) : B-63523EN-1
Refer to Section 9.11 “RIGID TAPPING.”
(b) For Series 30i/31i/32i
“FANUC Series 30i/31i/32i-MODEL A
CONNECTION MANUAL (FUNCTION) : B-63943EN-1
Refer to Section 11.11 “RIGID TAPPING.”
(c) For Series 15i
“FANUC Series 15i-MODEL B
CONNECTION MANUAL (FUNCTION) : B-63783EN-1
Refer to Section 9.8 “RIGID TAPPING.”
(d) For Series 0i
“FANUC Series 0i-MODEL C
CONNECTION MANUAL (FUNCTION) : B-64113EN-1
Refer to Section 9.10 “RIGID TAPPING.”

RETSV
RETSV Reference position return direction on servo mode (rigid
tapping/spindle positioning)
0 : The spindle performs a reference position return operation in the
CCW(counterclockwise) direction.
1 : The spindle performs a reference position return operation in the
CW(clockwise) direction.

SVMDRT
SVMDRT Whether to enable the rotation direction signal (SFR/SRV) function
on servo mode (rigid tapping/spindle positioning)
0 : Enables the rotation direction function.
If a move command from the CNC is positive (+),
(a) The spindle rotates in the CCW direction when the input
signal SFR (bit 5 of G70) = 1.
(b) The spindle rotates in the CW direction when the input
signal SRV (bit 4 of G70) = 1.
1 : Disables the rotation direction function.
If a move command from the CNC is positive (+), the spindle
rotates in the CCW direction when the input signal SFR = 1 or
SRV = 1.
