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".

Conversion formula for read access via bus system

Example 2: In order to set the parameter

C00012

(acceleration time main setpoint) to the value

"123.45 %" via a bus system, the integer value "12345" must be transferred, i.e. the value to be set

must be multiplied by the corresponding scaling factor "100".

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 inhibi-

ted.

PLC STOP

Parameter value can only be changed when the application is stop-

ped.

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.

MOT

Motor control parameters
