Subfault: 49.17
Description: Internal braking resistor utilization 105%
Response: Remote – critical fault
Cause Measure
Utilization of internal braking resistor reached switch-off
threshold of > 105%
Check the project planning and installation of the axis system.
Subfault: 49.18
Description: Internal device temperature
Response: Remote – critical fault
Cause Measure
Impermissible high device temperature detected. – Clarify the temperature condition of the axis system.
– Check ventilation of the control cabinet.
– Check mounting position, fan function.
– Check heat sink and fan for dirt and clean them.
Subfault: 49.19
Description: External error
Response: Remote – critical fault
Cause Measure
Another module bus station has requested external emergency
shutdown.
Eliminate emergency shutdown condition at the module bus
station.
Subfault: 49.20
Description: Capacity utilization 100%
Response: Remote – standard fault
Cause Measure
An electromechanical utilization of > 100% was detected by the
I2xT model.
– Check the project planning and installation of the axis sys-
tem.
– Contact the SEW-EURODRIVE Service.
Subfault: 49.21
Description: Internal braking resistor utilization 100%
Response: Remote – standard fault
Cause Measure
Utilization of internal braking resistor reached switch-off
threshold of > 100%
Check the braking resistor installation and the project planning
of the axis system.
– Contact the SEW-EURODRIVE Service.
Subfault: 49.22
Description: Overtemperature 100%
Response: Remote – standard fault
Cause Measure
The permitted heat sink temperature was exceeded. – Check mounting position and fan function.
– Check heat sink and fan for dirt and clean them.
– Check the project planning and installation of the axis sys-
tem.
Subfault: 49.23
Description: Module bus timeout
Response: Remote – standard fault
Cause Measure
The slave does not receive any telegrams. Check the module bus cable.
Subfault: 49.24
Description: Module bus initialization
Response: Remote – warning
Cause Measure
Module bus system not yet initialized. Check the module bus cable.
Subfault: 49.25
Description: Module bus CRC error
Response: Remote – standard fault
Cause Measure
CRC error Check the module bus cable.
