December 2001
You can start the spindle orientation with M4130. The nominal position is
taken from D592 and the speed from MP3520.1. The nominal position is with
respect to the reference point.
For example, the nominal position can be transferred with MP4210.x or taken
from the oriented spindle stop cycle (CYCL DEF 13). If the value is taken from
the cycle, you must set the MSB of D592 to 1 and the other bits to 0. M4016
is set during execution of Cycle 13.
From a standstill, the spindle is oriented on the shortest path. Prerequisite: At
the start, the distance between the nominal and actual position must not be
greater than the positioning window (MP3420). If the distance is greater than
the positioning window, the spindle is positioned according to M4013 with
M03 or M04.

Set M4011.
Then the spindle is moved in the direction from M4013 and at the speed from
MP3520.0. The spindle is stopped as soon as you reset M4011. The current
positioning value is shown in the status window.

After spindle orientation the offset is compensated automatically. In order to
give the spindle enough time to settle to a stop, the offset compensation is
delayed until the spindle has been in position for at least two seconds. The
offset is then compensated in intervals of 0.152 mV per second. The spindle
turns slowly due to the offset voltage.
