Fig. 6-85 Example: Programming the traversing block
If no bit is selected when selecting the block with the "spindle position-
ing on" command, then traversing block 0 is automatically selected.
The axis then positions with the values from traversing block 0.
In the example, Fig. 6-85 (Standard setting) the drive moves to the
position value zero degrees from the actual speed and direction of rota-
tion, at a search velocity of 72000 degrees/min (200 RPM).
If bit 0 is set in this state, when selecting the traversing block (via termi-
nal or PROFIBUS–DP), then the drive rotates according to the
ABS_POS mode in the clockwise sense with the max. velocity of
3600 degrees/min and remains stationary at the 90 degrees position.
After bit 0 is switched–out, the axis moves from 90 degrees to 0 de-
grees.
The "spindle positioning on" command must always be present. If the
command is switched–out, then the axis rotates at the speed of the
currently effective speed setpoint.
Search rate The search velocity depends on the initial velocity at the instant that the
"spindle positioning" function is activated at n–set (refer to Fig. 6-86).
In this case, the following parameters are effective:
P0082 Velocity
P0083 Acceleration override
P0084 Deceleration override
P0103 Max. acceleration
P0104 Max. deceleration
P0129 Spindle positioning, tolerance, search velocity
P0130 Spindle positioning, lowest search velocity
P0133 Spindle positioning, max. search velocity
P1256 Ramp–function generator, ramp–up time
P1257 Ramp–function generator, ramp–down time
