3. EXPLANATION OF
PARAMETERS
B–65160E/02
222
16i/1615 15i0
Velocity loop integral gain on orientation
6177 3357 3213 4213
6357 3577
Data unit :
Data range : 0 to 32767
Standard setting : 10
This data is used to set the velocity loop integral gain on spindle
orientation.
16i/1615 15i0
Velocity loop integral gain on servo mode
6178 3358 3214 4214
6358 3578
Data unit :
Data range : 0 to 32767
Standard setting : 10
This sets velocity loop integral gain in servo mode (rigid tap/spindle
positioning etc.).
16i/1615 15i0
Gear ratio (HIGH) CTH1A = 0
6180 3360 3216 4216
6360 3580
Gear ratio (LOW) CTH1A = 1
6181 3361 3217 4217
6361 3581
Data unit : Motor rotation for one rotation of spindle 100
(or 1000)
(When parameter No. 4182 #1 (GRUNIT) = 1,
motor rotation 1000)
Data range : 0 to 32767
Standard setting : 100 (Gear ratio=1:1)
These data are used to set the gear ratio between spindle and spindle
motor.
Set the gear or clutch status to correspond to the clutch/gear signal
(CTH1A) in the spindle control signals sent from the PMC to NC.
(Example) When the spindle rotates once, set ”250” as the data when
the motor rotates 2.5 times.
16i/1615 15i0
Position gain on orientation (HIGH) CTH1A =0
6182 3362 3218 4218
6362 3582
Position gain on orientation (LOW) CTH1A =1
6183 3363 3219 4219
6363 3583
Data unit : 0.01 sec
–1
Data range : 0 to 32767
Standard setting : 1000
These data are used to set the position gain on spindle orientation.
