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 802C, 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). For this reason, data have to be entered for the spindle, too; these data are descri-
bed for axis start-up.
Note
With SINUMERIK 802C, the 4th machine axis (SP) is fixed for the spindle.
The spindle settings for the 4th machine axis are contained in the default machine data.
The spindle setpoint (+10 V analog voltage signal) is output to X7. The spindle measuring
system must be connected to X6.
Spindle modes
The following modes are possible for the spindle:
S Control mode (M3, M4, M5)
S Oscillating mode (to assist gearbox change)
S Positioning mode (SPOS)
