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

Before activating the function, start up the explosion protection function.

Error: 52.2 (3402hex | 13314dec)

Description: Invalid function activated

 

Response: Output stage inhibit

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

Disable the "standstill current" function.

Error: 52.3 (3403hex | 13315dec)

Description: Nominal inverter current too large

 

Response: Output stage inhibit

Cause

Error: 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.

– Make sure that work is not performed below 5 Hz for a longer period of time.

– Check behavior in idle state. For instance, activate the "FCB 01 output stage inhibit" drive function for position hold control on the device.
