Fault 50 I/O card

Subfault: 50.1

Description: Boot synchronization timeout

 

Response: Output stage inhibit

Cause

Measure

I/O card is plugged but cannot be addressed.

– When using a pluggable safety card, check the device assignment of the basic device and the I/O card.

– When using a I/O card, check the installation.

– Switch the device off and on again.

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Subfault: 50.2

Description: FPGA driver – CRC error

 

Response: Output stage inhibit

Cause

Measure

Communication between FPGA and I/O card does not work or is disrupted.

– When using a I/O card, check the installation.

– Check for EMC-compliant installation.

– Switch the device off and on again.

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Subfault: 50.3

Description: CRC error

 

Response: Output stage inhibit

Cause

Measure

Checksum error on communication interface between I/O card and basic unit (SPI bus).

– When using a I/O card, check the installation.

– Check for EMC-compliant installation.

– Switch the device off and on again.

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Subfault: 50.4

Description: SPI bus timeout

 

Response: Output stage inhibit

Cause

Measure

Timeout on communication interface between I/O card and basic unit (SPI bus).

– When using a I/O card, check the installation.

– Check for EMC-compliant installation.

– Switch the device off and on again.

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Subfault: 50.5

Description: Watchdog error

 

Response: Output stage inhibit

Cause

Measure

Watchdog of I/O card processor detected an error.

– When using a I/O card, check the installation.

– Check for EMC-compliant installation.

– Switch the device off and on again.

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Subfault: 50.6

Description: Ready signal timeout

 

Response: Output stage inhibit

Cause

Measure

I/O card booted but cyclic communication is not possible.

– When using a I/O card, check the installation.

– Check for EMC-compliant installation.

– Switch the device off and on again.

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Subfault: 50.7

Description: Telegram error

 

Response: Output stage inhibit

Cause

Measure

Communication error between I/O card and basic unit.

– Replace the pluggable I/O card.

– Replace the basic device.

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Subfault: 50.8

Description: Invalid variant

 

Response: Output stage inhibit

Cause

Measure

I/O card variant not supported.

Use a correct variant of the I/O card.
