Activation
The LEC is only activated in all operating modes if the following requirements are met:
S
The number of compensation intermediate points must be defined. They are only active
after Power ON (MD: MM_ENC_MAX_POINTS).
!
Warning
Changing the MD: MM_CEC_MAX_POINTS[t] or MM_ENC_COMP_MAX_POINTS au-
tomatically reorganizes the NC user memory when the control system is booting. All user
data stored in the user memory (e.g. drive and MMC machine data, tool offsets, part pro-
grams, compensation tables etc.) are deleted.
S
Enter the compensation value for the intermediate point N in the compensation value table
(ENC_COMP_[0,N,Axi]).
S
Select the distance between the individual intermediate points (ENC_COMP_STEP
[0,Axi]).
S
Select the start position (ENC_COMP_MIN [0,Axi]).
S
Define the end position (ENC_COMP_MAX [0,Axi]).
S
In the NC, set MD: ENC_COMP_ENABLE(0)=0. This is the only way to load the compen-
sation table.
S
The compensation values for the machine axes are entered into the NC memory by means
of a part program (see also example in the Manual “Description of Functions“)
S
Approach the reference points in the axes. Then start the NC program with the leadscrew
error compensation table. The reference points must then be approached once more to set
the LEC active. The LEC function is activated by setting the MD: ENC_COMP_ENA-
BLE(0)=1 for each machine axis.
– Another possibility to create the LEC compensation table is by reading out the LEC file
from the NC via the V24 interface.
MD: MM_ENC_MAX_POINTS must be set depending on the number of axes to be
compensated. Select Service using the softkey, put the cursor to Data, and press the
Show softkey. Then select “Leadscrew Error” using the cursor and press the Data Out
softkey.
Enter compensation values, intermediate point distance, start and end position in the
received file _N_COMPLETE_EEC by means of the editor (e.g. in the PCIN/OUT pro-
gram). Then re–read the edited file into the control system. Approach the reference
point in the axes and set MD: ENC_COMP_ENABLE(0)=1. The LEC is thus activated.
4.7.3 Starting up the spindle
Overview
With the SINUMERIK 802S, the spindle is a subfunction of the entire axis functionality. The
machine data of the spindle are therefore to be found under the axis machine data (from
MD35000 onwards). For this reason, data have to be entered for the spindle, too; these data
are described for axis start-up.
