Control and Status Words 01.2004

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.
