	Contactor K1 is signaling an unsuitable switching status (e.g. closed, whereas it should be open).	Check the contactor for welding.

Error: 144.214 (90D6hex \| 37078dec) Description: IO communication error: The IO connector of the "DC synchronization" operating mode is signaling that its values are incorrect

	Cause	Measure
	The SBusPLUS communication is faulty and the IO module which supplies the values is not accessible.	– Check the SBusPLUS communication. – Check the cabling of the SBusPLUS.
	The interface to the "LogicalDevice" of the IO module has not been linked.	– Program the link. or – Disable the checking via Property. More information about this can be found in the manual.

Error: 144.215 (90D7hex | 37079dec)

Description: Current limits for test current implausible

Cause

Measure

CurrentLimit low (50100.47) is greater than CurrentLimit high (50100.48).

Contact SEW-EURODRIVE Service.

Error: 144.224 (90E0hex | 37088dec)

Description: The connected energy storage unit is signaling a general error

Cause

Measure

Internal error

Contact SEW-EURODRIVE Service.

Error: 144.225 (90E1hex \| 37089dec) Description: The connected energy storage unit is signaling overtemperature

	Cause	Measure
	The energy storage unit is being heavily loaded by high currents.	Shut down the system and allow storage unit to cool. If the fault occurs again, contact SEW-EURODRIVE service.
	The outside temperature is high, or there is a high temperature inside the switch cabinet.	– Check the ventilation. – Clean the dust filters.

Error: 144.226 (90E2hex | 37090dec)

Description: The connected energy storage unit is signaling low temperature

Cause

Measure

Temperature in the control cabinet is too low.

Move storage unit into a suitable environment.

Error: 144.227 (90E3hex | 37091dec)

Description: The connected energy storage unit is signaling wire break

Cause

Measure

The fault can be caused as follows:

– A wire break has occurred.

– There are loose contacts in the communication cables to the storage unit.

Check the communication lines to the storage unit for loose contacts or wire break.

Error: 144.228 (90E4hex | 37092dec)

Description: The connected energy storage unit is signaling overvoltage

Cause

Measure

Overvoltage is present in at least one of the cells in the storage unit.

Energy storage unit discharged.
