Scaling function control

This is only available when the encoder Class 2 or the encoder Class 2(+VEL) are
installed.
When this option is disabled (bit 3

Scaling function control

= 0 = DISABLED),

the device uses the hardware resolution, i.e. the hardware counts per revolution
and the hardware number of revolutions to arrange the absolute position
information, see the encoder data on the label applied to the device.
On the contrary, when it is enabled (bit 3

Scaling function control

= 1 =

ENABLED), the device uses the custom resolution transmitted through the bytes
from 11 to 18 to calculate the position information (see the

and

Total resolution

parameters).

For a correct use of this function see the “7.4.2 Bytes 11 … 14“ and “7.4.3 Bytes
15 … 18“ sections.
Default = 1 (min. = 0, max. = 1)

WARNING

When you enable the scaling function (

Scaling function control

= 1), please

enter scaled values next to the

Counts per revolution

and

Total resolution

parameters that are consistent with the physical values. In the case of
inconsistent values, the system does not go online.

WARNING

Every time you enable the scaling function and/or change the scaled values (see
the

Counts per revolution

and

Total resolution

parameters), then you are

required to set a new preset value (see the the

Preset value

parameter).

WARNING

You can activate the custom values set next to the

Counts per revolution

and

Total resolution

parameters only if

Class 2 functionality

= ENABLED.

If

Scaling function control

= ENABLED the set custom resolution values are

enabled and used by the encoder; on the contrary, if

Scaling function control

= DISABLED you are allowed to set new resolution values, however they are not
enabled even if sent to the encoder: the encoder still goes on using the physical
values, NOT the new entered values, until you enable the

Scaling function

Exchange type

0 = Position = the device transmits only the position value (Class 1 and Class 2).
1 = Po velocity = the device transmits both position and velocity values
(Class 2(+VEL)).
Default = 0 (min. = 0, max. = 0) for Class 1 and Class 2
Default = 1 (min. = 1, max. = 1) for Class 2 (+VEL)
