6.15 Spindle positioning (from SW 5.1)
Using the ”spindle positioning” function, in the ”n–set” mode, the
spindle can be traversed to a specific position and then held there.
The function is activated in the ”n–set” mode (P0700 = 1) via the input
signal ”spindle positioning on” or via PROFIBUS–DP (STW1.15), if
P0125 = 1 (spindle positioning active).
Note
If the ”spindle positioning” function is carried–out using NC functionality
(e.g. SINUMERIK 802D), then P0125 must be set to 0 (spindle
positioning de–activated).
In addition, a traversing block number must be entered
via a terminal or PROFIBUS–DP. If a bit is not selected for the travers-
ing block number, then data in traversing block 0 is used.
The following is mainly defined in the traversing block:
 The target position (also via PROFIBUS–DP control word XSP is
possible, being prepared)
 The search velocity, and
 How the axis approaches the target position:
The target position can be approached as follows:
 With the actual direction of rotation
 With a defined direction of rotation (clockwise, counter–clockwise)
 With a motor encoder (sin/cos 1 Vpp)
 With a motor encoder (sin/cos 1 Vpp) and external zero (BERO) at
the spindle when the gearbox stage is being changed–over
 with direct measuring system (spindle encoder, sin/cos 1 Vpp) via
encoder connection X412 (drive B)
 Spindle positioning only with motor 1.
 If spindle positioning has been selected, then the encoder informa-
tion for PROFIBUS–DP (G1_STW, G1_ZSW) is no longer precisely
transferred.
 If ”spindle positioning on” is selected using a terminal or PROFI-
BUS–DP (for P0125 = 1), then the ”relative” positioning mode
(P0087:64) may no longer be programmed in the currently selected
traversing block.
 When spindle positioning is selected, it is not possible to change
over the motor via PROFIBUS–DP.
 Spindle positioning is not supported in conjunction with the absolute
measuring system.
