2. FUNCTION EXPLANATION
FANUC AC SPINDLE MOTOR a series
111
0: Rotation direction function enabled
When bit 1 (ROTA2) of parameter No. 4000 is 0
With a + motion command, the spindle rotates counterclockwise
when SFR = 1, and the spindle rotates clockwise when SRV = 1.
When bit 1 (ROTA2) of parameter No. 4000 is 1
With a + motion command, the spindle rotates clockwise when
SFR=1, and the spindle rotates counterclockwise when SRV=1.
1: Rotation direction function disabled
The rotation direction function of the SFR/SRV signal is disabled.
Only the function for enabling spindle motor excitation is
available.
When bit 1 (ROTA2) of parameter No. 4000 is 0
With a + motion command, the spindle rotates counterclockwise
when SFR = 1 or SRV = 1.
When bit 1 (ROTA2) of parameter No. 4000 is 1
With a + motion command, the spindle rotates clockwise when
SFR = 1 or SRV = 1.

HRPC: Specifies whether to use high–resolution position coder.
0: Does not use high–resolution position coder.
1: Uses high–resolution position coder.

RFCHK1 CMTVL FFSMTH
6516 3016 3016 4016
FFSMTH:
Specifies whether to use the smoothing function under feed forward
control.
0: Uses the smoothing function.
1: Does not use the smoothing function.
This bit specifies whether to use the smoothing function under feed
forward control in Cs contouring control mode.
CMTVL:
Specifies the control characteristic in Cs contouring control mode.
Normally, set this bit to 0. Check that 100 is specified for the parameter
for the motor voltage in Cs contouring control mode (parameter No.
4086).
When a value of less than 100 is to be specified in the motor voltage
parameter (No. 4086), set this bit to 1.
RFCHK1:
Specifies whether to use the one–rotation signal error detection
(AL–39) function for the detector in Cs contouring control mode.
0: Does not use the one–rotation signal error detection function.
1: Uses the one–rotation signal error detection function.
