Siemens 400 V / 210...590 A operating instructions Bit 6 Starting lockout signal H High signal

01.2004 Control and Status Words

Bit 6: "Starting lockout" signal (H)

HIGH signal	STARTING LOCKOUT state (008)
Meaning	♦ The power supply, open-loop control and closed-loop control are all
	operative.
	♦ The signal is continuously applied as long as an OFF2 command via
	control word bit 1 or an ON command via control word bit 0 is active
	(edge evaluation).
	Output at terminal strip (CUSA, SCB1) with L signal.

Bit 7: "Alarm" signal" (H)

HIGH signal	Alarm (Axxx)
Meaning	♦ An alarm (type irrelevant) has occurred.
	♦ This signal remains active until the cause has been eliminated.
	Output at terminal strip (CUSA, SCB1) with L signal.

Bit 8: "Setpoint/actual value deviation" signal (L)

LOW signal	"Setpoint/actual value deviation" alarm (A034)
Meaning	♦ There is currently a deviation between the Vd setpoint and Vd actual
	value which is greater than the setting in P517 (set/act.val.dev. Vd)
	and active for longer than P518 (set/act.val.dev.time).
	♦ The bit is reset to an H signal as soon as the deviation decreases to
	below the setting in parameter P517.

Bit 9: "PZD control requested" signal (H)

HIGH signal	This signal is always active.
Bit 10: Reserved
Bit 11: "Undervoltage fault" signal (H)
HIGH signal	"Undervoltage in DC link" fault (F008)
Meaning	♦ The DC link voltage has dropped below the permissible limit value.
	See Section "Fault and alarm messages"
	Output at terminal strip (CUSA, TSY, SCI1/2) with L signal.

Bit 12: "MC energized" signal (H)

HIGH signal	The main contactor is energized.
WARNING
	On the AFE, this status bit is always connected to digital output 2 on
	the CUSA. A different wiring is not possible and is also not allowed
	because the AFE inverter might be destroyed if the main contactor is
	activated before the DC link has been precharged.
