3.6 Communication times

The communication times depend on:

the data transfer time

the processing time in the controller

3.6.1 Data-transfer time

The data-transfer time depends on:

the baud rate

the user-data length

You will find more information about the data-transfer time in the documentation for your host

system.

3.6.2 Processing time in the controller

Processing time 820X

For the 820X series several processing steps are required, which are processed cyclically.

A processing cycle consists of:

Writing of control word or setpoint, if the value has changed

Alternating reading of status word and actual value

Processing of parameter access if there is a service

If the time tolerances caused by the cyclic reading of the status word/actual value are too large, the

alternating reading of the status word and the actual value can be suppressed. This is controlled by

the bit 15 (PE inhibit) of the DRIVECOM control word:

PE inhibit = 0:

Status and actual-value update active

PE inhibit = 1:

Status and actual value update not active

A suppression of the processing of parameter access is not necessary, since this is controlled by

the user.
