Danfoss VLT series Programming Guide

NOTICE
The digital output must be congured to be used for the
digital CAM switching functionality by using object
0x2FFF (see chapter 7.21.5 Parameter 52-05: Digital
Output Conguration (0x2FFF)). Otherwise, the activation
of the digital CAM switch has no eect.
This functionality can be commanded via PLC by using
function blocks DD_PrepareDigCamSwitch_ISD51x and
DD_DigitalCamSwitch_ISD51x.

Description
version O x.x.x.x Gives the version of
the digital CAM
switches denition.
Table 2.58 Attributes for DigitalCamSwitch Element
The DigitalCamSwitch element contains the following
optional elements:
•
OnCompensation (see chapter 7.17.1 Parameter: On
Compensation (0x3840)).
•
OCompensation (see chapter 7.17.2 Parameter: O
Compensation (0x3841)).
If those elements are present, the parameters are written
to the object dictionary at the point of enabling of the
digital CAM.
When disabling the digital CAM switching functionality, the
values persist (that is, they do not switch back to values,
before the enabling). It is also possible to change those
values during the operation of the digital CAM by writing
dierent values to the objects. This does not change the
content of object 0x3844 (see chapter 7.17.5 Parameter:
Digital CAM Switches Data (0x3844)).
Switches is a mandatory element.

Description
Unit M User/

Denes the unit in which
all the position values in
this le are given. Allowed
values are:
•
User: The position
values are given in user-
dened position units.
All numerical values
accept integers only.
•
Revolutions: The
position values are
given in shaft
revolutions (matching
the units that are used
in CAM mode). The
numerical values accept
oats and integers.

See
chapter 7.17.3 Parameter:
Hysteresis (0x3842) for the
description. This parameter
is written to the object
dictionary at the point of
enabling of the digital
CAM. When disabling the
digital CAM switching
functionality, the value
persists (that is, it does not
switch back to value before
the enabling). It is also
possible to change this
value during the operation
of the digital CAM by
writing a dierent value to
the object. It is not
possible to change the
parameter in the le on-
the-y. The unit of this
value depends on the Unit
attribute of the Switches
element.
