Fault 52 Ex protection function category 2

Fault: 52.1 (3401hex \| 13313dec) Description: Startup error
	Response: Output stage inhibit
Cause	Measure
One or several parameters of the explosion protection function have been changed.	Before activating the function, take the explosion protection function into operation.

Fault: 52.1 (3401hex | 13313dec)

Description: Startup error

Response: Output stage inhibit

Cause

Measure

One or several parameters of the explosion protection function have been changed.

Before activating the function, take the explosion protection function into operation.

Fault: 52.2 (3402hex \| 13314dec) Description: Invalid function activated
	Response: Output stage inhibit
Cause	Measure
The explosion protection function and the "standstill current" function may not be active at the same time.	Disable the "standstill current" function.

Fault: 52.2 (3402hex | 13314dec)

Description: Invalid function activated

Response: Output stage inhibit

Cause

Measure

The explosion protection function and the "standstill current" function may not be active at the same time.

Disable the "standstill current" function.

Fault: 52.3 (3403hex \| 13315dec) Description: Nominal inverter current too large
	Response: Output stage inhibit
Cause	Measure
Ratio of nominal inverter current and nominal motor current too large.	Check the assignment of motor and inverter.

Fault: 52.3 (3403hex | 13315dec)

Description: Nominal inverter current too large

Response: Output stage inhibit

Cause

Measure

Ratio of nominal inverter current and nominal motor current too large.

Check the assignment of motor and inverter.

Fault: 52.4 (3404hex \| 13316dec) Description: Parameterization of current limit characteristic faulty
	Response: Output stage inhibit
Cause	Measure
Error setting parameters for current limit characteristic.	– Perform startup again. – If the error occurs repeatedly, contact SEW-EURODRIVE Service.

Fault: 52.4 (3404hex | 13316dec)

Description: Parameterization of current limit characteristic faulty

Response: Output stage inhibit

Cause

Measure

Error setting parameters for current limit characteristic.

– Perform startup again.

– If the error occurs repeatedly, contact SEW-EURODRIVE Service.

Fault: 52.5 (3405hex \| 13317dec) Description: Time duration exceeded for f < 5 Hz
	Response: Emergency stop + output stage inhibit
Cause	Measure
The rotating field frequency must not be below 5 Hz for longer than 60 s. This time period has been exceeded.	– Check the project planning. – Ensure that operation is no longer below 5 Hz. – Check the behavior at standstill. For example, activate the drive function "FCB 01 Output stage inhibit" on the device when using position hold control.
