9.4 Analog axes.
9.4.1 Configure the number of the analog output and of the feedback input.
Both the feedback input and the velocity command output are configured by machine
parameters. Each axis has the following machine parameters to configure it.
Configure the analog output of the axis.
The velocity command for an analog axis may be taken from an analog output of the remote
modules or of a Sercos drive. It is selected with parameter ANAOUTID. In either case, this
parameter indicates the analog output used for the command.
Managing the analog command from CANfagor remote modules.
In this case, this parameter indicates the number of the analog output used for the command.
The analog output modules are numbered following the logic order of the remote groups
(rotary switch of the power supply). If there are several analog-output modules in each group,
the order is from top to bottom and from left to right. The analog outputs of the first module
will be 1 through 4, those of the second module 5 through 8 and so on.
Managing the analog command from Sercos drives.
In this case, this parameter indicates the number of the analog output and the drive to be
used. The parameter is set with a three-digit number; the first digit indicates the number of
the analog output to be used (1 or 2) and the other two digits indicate the logic address of
the drive (1 through 32). The "address" rotary selector switch sets the logic address.
For example, if the parameter is with a value of ·107·, it indicates that the CNC uses analog
input ·1· of the drive whose logic address is ·7·
Configure the feedback input for the axis.
The feedback inputs for an analog axis may be located in remote modules, in a Sercos drive
or locally in the central unit itself. It is selected with parameter COUNTERTYPE.
Once it has been determined where the feedback input is, Parameter COUNTERID must be
set indicating which feedback input will be used (either local or remote) or the drive number.
When using the feedback input of a Sercos drive, home search is not possible; therefore,
the axis must have absolute feedback.
Parameter. Meaning.
ANAOUTID Number of the analog output associated with the axis.
