PARAMETERS
B–65160E/02
238
16i/1615 15i0
Command multiplier for spindle orientation by a position coder
(MAIN side)
6292 3472 3328 4328
6472 3692
Command multiplier for spindle orientation by a position coder
(SUB side)
6293 3473 3329 4329
6473 3693
Data unit :
Data range : 0 to 32767
Standard setting : 0
Set a command multiplier for the spindle orientation function with an
externally set incremental command.
When 0 is set in these parameters, 1 is assumed to have been specified.
To use spindle speed control, set 4096 in these parameters.
16i/1615 15i0
Motor excitation delay for spindle orientation (MAIN side)
6294 3474 3330 4330
6474 3694
Motor excitation delay for spindle orientation (SUB side)
6295 3475 3331 4331
6475 3695
Data unit : 1 msec
Data range : 0 to 32767
Standard setting : 0
When 0 is set in these parameters, a specification of 50 msec is
assumed. The setting of these parameters is valid only when the speed
is within the range from the speed zero detection level (SST = 0) to the
orientation speed.
If overshoot occurs when the spindle stops during spindle orientation
from a speed within the range from the speed zero detection level (SST
= 0) to the orientation speed, overshoot can be suppressed by setting a
value greater than 50 msec.
16i/1615 15i0
Arbitrary number of speed detector pulses (MAIN side)
6298 3478 3334 4334
6478 3698
Arbitrary number of speed detector pulses (SUB side)
6299 3479 3335 4335
6479 3699
Data unit : 1 l/rev (number of speed detector teeth)
Data range : 0, 32 to 1024
Standard setting : 0
Set these parameters when the number of teeth of the speed detector
mounted onto the motor is other than 64, 128, 256, 512, 192, or 384.
When 0 is set in these parameters, the settings of bits 2, 1, 0 (VDT3, 2,
1) of parameter No. 4011 and bits 2, 1, 0 (VDT3, 2, 1) of parameter
No. 4187 are assumed, respectively.
