Monitoring parameters
These can only be read – "r" parameters
These parameters are used to display internal quantities, for example states and
actual values. These parameters are absolutely necessary, especially for
diagnostics.
Notation:
r0002 monitoring parameter 2
r0052.3 monitoring parameter 52, bit 03
r0947[2] monitoring parameter 947 index 2
r0964[0...4] monitoring parameter 964 with 5 indices (indices 0 to 4)
Abbreviated notation
r0964[5] monitoring parameter 964 with 5 indices (indices 0 to 4)
NOTE
¾ A parameter (e.g. P0013[20]) with x consecutive
elements (in this case: 20) is defined using an index. x is
defined by the numerical index value. When transferred to
a parameter this means that an indexed parameter can
assume several values. The values are addressed via the
parameter number including the index value (e.g.
P0013[0], P0013[1], P0013[2], P0013[3], P0013[4], ...).
Index parameters, for example, are used for:
Drive data sets
Command data sets
Sub-functions
In addition to the parameter number and parameter text, every setting and
monitoring parameter has different attributes which are used to individually define
the properties/characteristics of the parameter. The attributes are listed in the
following Table which are used for MICROMASTER.

Attribute Description
The data type of a parameter defines the maximum possible value range. 3 data
types are used for MICROMASTER. They either represent an unsigned integer value
(U16, U32) or a floating-point value (float). The value range is frequently restricted by
a minimum, maximum value (min, max) or using drive inverter/motor quantities.
U16 Unsigned, integer value with a size of 16 bits,
max. value range: 0 .... 65535
U32 Unsigned, integer value with a size of 32 bits
max. value range: 0 .... 4294967295
Data types
Float A simple precise floating point value according to the IEEE standard format
max. value range: -3.39e
