16i/1615 15i0
Modification rate of position gain on orientation completion
6184 3364 3220 4220
6364 3584
Data unit : 1%
Data range : 0 to 1000
Standard setting : 100 (100%)
This data is used to set the modification rate of position gain on
spindle orientation completion.
16i/1615 15i0
Position gain on servo mode (HIGH) CTH1A =0
6185 3365 3221 4221
6365 3585
Position gain on servo mode (LOW) CTH1A =1
6186 3366 3222 4222
6366 3586
Data unit : 0.01 sec
–1
Data range : 0 to 32767
Standard setting : 1000
This sets position gain in servo mode (rigid tap/spindle positioning
etc.)
16i/1615 15i0
Grid shift amount in servo mode
6187 3367 3223 4223
6367 3587
Data unit : 1 pulse (360_/4096)
Data range : 0 to 4095
Standard setting : 0
Set this parameter when shifting reference point in servo mode (rigid
tap/spindle positioning etc.).
In + data, spindle reference point shifts for set pulse in CCW direction.
16i/1615 15i0
Orientation completion signal detection level
6190 3370 3226 4226
6370 3590
Data unit : Position coder method → "1 pulse unit
Magnetic sensor method → "0.1 degree unit
Data range : 0 to 100
Standard setting : 10
This data is used to set the detecting level of orientation completion
signal (ORARA).
When the spindle position is located within the setting data on
orientation completion, the bit of orientation completion signal
(ORARA) in the spindle control signals is set to ”1”.
