GE 2300 V Failed to close, MA pickup time, Main Contactor Configuration, Local flt, Over speed

No.	Name	Type	Description
3	Cont failed to close	Trip	The Cont failed to close trip fault occurs when contactor A is commanded to
			open or close and fails to do so within the allowed time (defined by parameter
			MA pickup time).
			Primary causes:
			The contactor A feedback is missing or bad.
			Possible configuration faults:
			The allowed time for contactor A to open and close is too short. The allowed
			time is represented by parameter MA pickup time.
			Contactor A feedback is enabled when no contactor is present in the system.
			In the absence of the contactor, parameter MA contactor fbk should be set
			equal to Disable.

			Main Contactor Configuration
4	Local flt	Trip	The Local flt trip fault occurs when the local permissive circuit is open and a
			Run request, Jog request, Full flux request, or diagnostic test (cell test, pulse
			test, autotune) request is issued.
			Possible wiring faults:
			The connections to ATBA terminal board locations 8 (L115), 10 (L24), and 12
			(LCOM) are missing or damaged.
			The connection to backplane connector J2 is missing or damaged.
5	Tool requested trip	Trip	The Tool requested trip trip fault is generated from the engineering monitor
			issuing the “uf” command. It is for test purposes only.
6	Run cmd during init	Alarm	The Run cmd during init alarm occurs when a Run request, Jog request, Full
			flux request, or diagnostic test (cell test, pulse test, autotune) request is issued
			during drive initialization. When the alarm occurs, the request to perform a
			drive action is ignored.
			Primary causes:
			The external application layer issues a request to perform a drive action during
			drive initialization.
			An external input (i.e. digital input) used to request a drive action was high
			during drive initialization.
7	Over speed	Trip	The Over speed trip fault occurs when the magnitude of speed (variable
			Speed reg fbk) is greater than the over speed threshold (parameter Over
			speed flt level).
			Primary causes:
			Motor speed is too high.
			Possible configuration faults:
			Parameter Over speed flt level is set too low.
			Related functions:
			Speed Control Fault Check
8	Timed over current	Trip	The Timed over current trip fault occurs when one of the squared phase
			currents (variables Ia^2 filtered, Ib^2 filtered, and Ic^2 filtered) in the timed
			over current detection model exceeds the timed over current threshold level.
			This fault indicates that the motor has exceeded its thermal limit.
9	EE flash corrupted	Trip	The EE flash corrupted trip fault occurs when the memory containing the drive
			parameters is determined to be bad during drive initialization.
			EE flash corrupted requires a hard reset to clear.
