11.1.4 Parameter attributes
The table footers contain the parameter attributes:
Scaling factor
The "scaling factor" is important for parameter access via a bus system.
Example 1: The value "654" of the parameter C00028/1 (AIN1: input voltage) read via a bus
system must be divided by the corresponding scaling factor "100" to obtain the actual
display value "6.54 V".
[11-1] Conversion formula for read access via bus system
Example 2: In order to set the parameter C00012 (acceleration time - main setpoint) to the
value "123.4 s" via a bus system, the integer value "123400" must be transferred, i.e. the
value to be set must be multiplied by the corresponding scaling factor "1000".

Attribute Meaning
;
Read access Read access to parameter possible.
;
Write access Write access to parameter possible.
• Please also observe the following attributes:
;
CINH Parameter value can only be changed when the controller is
inhibited.
;
PLC STOP Parameter value can only be changed when the application is
stopped.
;
No transfer Parameter is not transferred to controller when the command Download parameter set is
executed.
;
COM Communication-relevant parameter
• This parameter is relevant for parameter data transfer via the (CAN) system bus.
