Bit 13: Reserved

Bit 14: "Motor operation" signal (L)

LOW signal

AFE operates in rectifier mode (active current >= 0)

 

 

Bit 15: Reserved

 

 

 

Bit 16: Reserved

 

 

 

Bit 17: Reserved

 

Bit 18: "Current limit active" signal (L)

LOW signal

AFE operates at the present current limit setting

Meaning

♦ If the AFE output current is limited, the DC-link voltage can no

 

longer be regulated to the selected setpoint.

 

Output at terminal strip (CUSA, SCB1) with L signal.

Bit 19: "External fault 1" signal (H)

HIGH signal

" External fault 1"

Meaning

♦ An "External fault 1" is active in control word bit 1.

 

Output at terminal strip (CUSA, SCB1) with L signal.

Bit 20: "External fault 2" signal (H)

HIGH signal

" External fault 2"

Meaning

♦ An "External fault 2" is active in control word bit 26.

 

Output at terminal strip (CUSA, SCB1) with L signal.

Bit 21: "External alarm" signal (H)

HIGH signal

"External alarm"

Meaning

♦ An "External alarm 1" is active in control word bit 28 or an "External

 

alarm 2" in control word bit 29.

 

Output at terminal strip (CUSA, SCB1) with L signal.

Bit 22: "AFE i2t alarm" signal (H)

HIGH signal Meaning

"AFE i2t alarm" (A025)

♦If the converter continues to operate under the current load conditions, the AFE will be thermally overloaded.

Output at terminal strip (CUSA, SCB1) with L signal.
