Sag/angularity complete-CEC compenzation (Siemens Sinumerik)

Sag/angularity complete-CEC compenzation

To set the sag/angularity compensation (between the axis Compensation) it is necessary to have the appropriate option purchased!!!

To set the compensation, do the following:

Parameter 18342-$MN _mm_cec_max_points -we set the number of points for Compensation.

Parameter 18342 (0)-table No. 0,18352 (1) table 1 etc. Parameter 32710 MA_CEC_ENABLE = 1 active compensation, 0 Inactive compensation

Caution After NCK reset (changing parameter 18342), memory (loss of Data) will be reorganized!!!!

After overriding the 18342 parameter (before NCK reset), It is necessary to create an archive of Serial UDP-NC including compensation data (commissioning) and Reload.

Then in the NC directory  NC active data-sag/angularity  complete-creates compensation file(CEC),make the archive (output data, archive, name the file, format-punched tape), you can edit them.

The CEC compensation file looks like the following:

CHANDATA (1)                   position Y

$AN _cec [0.0] = 0           -1000

$AN _cec [0.1] = 0.05      -950

$AN _cec [0.2] = 0.03     -900

$AN _cec [0.3] = 0.01      -850

$AN _cec [0.4] = 0.06     -800

$AN _cec [0.5] = 0.09      -750

$AN _cec [0.6] = 0.11      -700

$AN _cec [0.7] = 0.12      -650

$AN _cec [0.8] = 0.06     -600

$AN _cec [0.9] = 0.03      -550

$AN _cec [0.10] = 0          -500

$AN _cec [0.11] =-0.3       -450

$AN _cec [0.12] =-0.06    -400

$AN _cec [0.13] = 0.01      -350

$AN _cec [0.14] = 0.07      -300

$AN _cec [0.15] = 0.03      -250

$AN _cec [0.16] = 0.01     -200

$AN _cec [0.17] = 0.02     – 150

$AN _cec [0.18] = 0.03      -100

$AN _cec [0,19] = 0.015      -50

$AN _cec [0.20] = 0             -0

$AN _cec_input_axis [0] = (Y)-input Axis

$AN _cec_output_axis [0] = (Z)-output Axis

$AN _cec_step [0] = 50-distance points

$AN _cec_min [0] =-1000-start of compensation (minimum ref. Y-axis Position)

$AN _cec_max [0] = 0-end of compensation (maximum ref. Y Position)

$AN _cec_direction] = 0

$AN _cec_is_ MODULO [0] = 0-switch on the rotary axis module

M17

value =   …..is the compensation value e.g. 0.01 The system shifts the measuring by 0.01 mm.

After editing the  table ,upload back(data input, archive, select file, upload)

When loaded the parameter 32700 ENC_COMP_ENABLE (activation Compensation) must be in 0!!!!!

Then set the parameter 32700 to 1 compenzation should Work.

When changing the $AN _cec_input_axis], $AN _cec_output_axis [0], $AA _cec_comp_step, $AA _cec_comp_min, $AA _enc_comp_max need to give NCK reset!!!!

Always make a backup of your data before you start your Work. Archive for serial start up!!!!

Setting on your own responsibility, we recommend that you have a professional service company.
