For details of the serial spindle parameters, refer to the “FANUC AC
SPINDLE MOTOR a series PARAMETER MANUAL (B–65160E)” or
“FANUC AC SPINDLE MOTOR ai series PARAMETER MANUAL
(B–65280EN)”.
4044 Proportional gain of the velocity loop in servo mode (gear 1, gear 2)
4045 Proportional gain of the velocity loop in servo mode (gear 3, gear 4)
[Valid data range] 0 to 32767
Set a proportional gain for the velocity loop in a servo mode (such as rigid
tapping mode).
4052 Integral gain of the velocity loop in the servo mode (gear 1, gear 2)
4053 Integral gain of the velocity loop in the servo mode(gear 3, gear 4)
[Valid data range] 0 to 32767
Set an integral gain of the velocity loop in a servo mode (such as rigid
tapping mode).
4065 Position gain in the servo mode (HIGH)
4066 Position gain in the servo mode (MEDIUM HIGH)
4067 Position gain in the servo mode (MEDIUM LOW)
4068 Position gain in the servo mode (LOW)
[Unit of data] 0.01 sec
–1
[Valid data range] 0 to 65535
Set a servo loop gain in a servo mode (such as rigid tapping mode).
CAUTION
1 Set a loop gain for spindle position control in rigid tapping
using a serial spindle. In these parameters, basically, set
the same values as those set in parameter Nos. 5280 and
5281 to 5284 (loop gains for position control of the tapping
axis).
Which serial spindle parameter (i.e., loop gain) is actually
used to operate the spindle depends on the serial spindle
clutch/gear selection signals CTH1 and CTH2 (G070#3, #2
for the first spindle, and G074#3, #2 for the second spindle).
Accordingly, which parameter is to be used must be
determined by considering the gear switching and PMC
software.
