Cause Missing or incorrect I/O mapping

In the case of Servo Drives 9400 and Inverter Drives 8400, the ports in the »Engineer« are

displayed incorrectly or not at all.

Error message -

Remedies Check and correct the mapping settings in the control configuration and in the inverter.

When the Lenze Controller is started, the complete configuration/PDO mapping is written

into the EtherCAT slaves. When this is done, mapping entries, e.g. from the »Engineer« are

overwritten.

Cause Variables are not used in the »PLC Designer« application.

I/O variables that are not used in the »PLC Designer« application are not copied into the

process image (and vice versa) so that they are not updated by the peripherals.

Error message -

Remedies With the slave, go to the EtherCAT I/O Mapping tab and set a checkmark at Always update

variables:

1 2 ... 174 175 176 177 178 179 180 181 182 183 184 ... 204 205
