Extended Drive Functions
Outputting Voltage Signals Independent of the Drive
The machine control unit can output voltage signals independent of the
drive at the analog outputs of the drive. Signals from the master can be
directly assigned to the analog outputs via the master communication
system between drive and master.
The control master directly writes values to the following parameters that
are within the limits of the value range of the respective analog output:
• P-0-0139, Analog output 1
• P-0-0140, Analog output 2
• P-0-0414, Analog output 3
• P-0-0415, Analog output 4
This output mode is the default setting for the analog outputs (basic
parameter set). It can be changed or assigned again in P-0-0427, Control
parameter of analog output.
Note: In the case of double-axis device (HMD01.1-..., control section
CDB01.1-....) analog outputs are used by both axes. Specific
parameters, assigned to the individual analog output pin, are
identical for both axes!
See Parameter Description "P-0-0427, Control parameter of
analog output"
Extended Output of Parameters with Binary Format
For the output of binary parameters, such as S-0-0403, Position
feedback value status, the following parameters are irrelevant and write-
protected:
• P-0-0422, Analog output, assignment A, scaling [1/V]
• P-0-0425, Analog output, assignment B, scaling [1/V]
Which bit of the respective parameter is to be output is determined in the
following parameters:
• P-0-0418, Analog output, assignment A, signal value at 0V
• P-0-0419, Analog output, assignment B, signal value at 0V
The output voltage is 1 V when the respective bit has been set, otherwise
0 V are output.
Extended Output of Internal Storage Locations
For special diagnostic purposes in exceptional cases there are extended
possibilities of setting for the analog outputs. To use these possibilities of
setting it is necessary to know the structure of the drive firmware. The
extended setting can therefore only be made by the development staff. If
functions of the extended analog output are required it is necessary to
contact our development department.
