3.12.1.18

ETM motor type (23)

Application-specific motor type with pulse duration measurement for actual value acquisition
3.12.1.19

ANA_SIGN_SSI motor type (24)

Axis with analog manipulated variable output and actual value acquisition through SSI absolute encoder
(similar to SSI type 2 and ANA_SIGN type 19). The analog output signal is always positive; the directional
information is output through the digital output. Here, for positive manipulated variable output, an
environment variable SIGNOUTPOS? can be defined, and for negative manipulated variable output, an
environment variable SIGNOUTNEG?, with the attached „?" representing the axis index. In the SIGNOUT...
value, the digital output is specified in a bit-coded form (output 1 = 1, output 2 = 2, output 3 = 4, ... output 8
= 128, etc.). Here, also none or more outputs can be specified.
Example:
nd
2 axis, positive manipulated value = output 4, negative manipulated value display is not required
set MT1 24
set SIGNOUTPOS1 8
set SIGNOUTNEG1 0
In this case, SIGNOUTNEG1 can also remain undefined.
3.12.1.20

ANA_SIGN_ENDAT2_2 motor type (25)

Axis with analog manipulated variable output and actual value acquisition through ENDAT 2.2 absolute
encoder (similar to ENDAT 2.2 type 16 and ANA_SIGN type 19). The analog output signal is always positive;
the directional information is output through the digital output. Here, for positive manipulated variable output,
an environment variable SIGNOUTPOS? can be defined, and for negative manipulated variable output, an
environment variable SIGNOUTNEG?, with the attached „?" representing the axis index. In the SIGNOUT...
value, the digital output is specified in a bit-coded form (output 1 = 1, output 2 = 2, output 3 = 4, ... output 8
= 128, etc.). Here, also none or more outputs can be specified.
Example:
nd
2 axis, positive manipulated value = output 4, negative manipulated value display is not required
set MT1 24
set SIGNOUTPOS1 8
set SIGNOUTNEG1 0
In this case, SIGNOUTNEG1 can also remain undefined.

3.12.2 The environment variable NumberAxis

This environment variable enables to set the axis number. The default value is 3. This value is normally set
for operation and is only to be modified with values which are supported by the hardware and software
configuration of the control.

3.12.3 The environment variable SampleTime

Through this environment variable the scan time (control cycle time and interpolation cycle time) of the
control is set in microseconds. The values are between 100 and 5000. The default value is 1280. This value
can only be modified with values which can be reached by the hardware and software configuration of the
control. Realistic values begin from approximately 300. Please note that by modifying the scan time, the filter
parameters must generally be adapted as well, especially the pre-control coefficients kfcv and kfca.
