Panasonic MINAS A3 Series Undervoltage, Error response, At main power-off, Dynamic breke, Action

[Connections and Settings in Torque Control Mode]

							Default setting is shown by [ ]
Parameter	Parameter Name	Setting	Unit			Function/Description
No.		range
65	Undervoltage	0 – 1	–	The parameter sets whether to enable the “protection against main power
	error response			source under-voltage” function when you shut down the main power of
	at main power-off			main and control power supplies.
					Setting value	Main Power Source Under-voltage Protection Action
						In this case, if you shut off the main power during Servo ON, it
					0	will be SERVO-OFF without a trip. Then, when the main pow-
						er supply turns ON again, it will be recovered to Servo ON.
						Shutting off main power during Servo ON will activate ab-
					[1]	normal main power supply under-voltage (alarm code
						No.13) and cause a trip.
				Refer to the timing chart “At Power ON” of Preparations volume on page 40.
66	Dynamic breke	0 – 1	–	The parameter sets driving conditions at decelerated operation after over-
	inhibition at			travel input inhibit (CCWL: connector CN X5 9-pin or CWL: connector CN
	overtravel limit			X5 8-pin) has been activated and enabled.
					Setting value	Driving Conditions from Deceleration to Stop
					[0]	The motor decelerates and stops as the dynamic brake (DB) is
						operated. The motor will be in free condition after it stops.
					1	Free running, the motor decelerates and stops. The motor
						will be in free condition after it stops.
67	Error response	0 – 7	–	The parameter sets:
	at main power-off			(1) Driving conditions during deceleration and after stopping; and
				(2) Processing to clear content of the deviation counter
				after the main power source is shut off.
					Setting	Driving Conditions		Content of Deviation
					value	During Deceleration	After Stopped	Counter
					[0]	DB	DB	Clear
					1	Free Run	DB	Clear
					2	DB	Free	Clear
					3	Free Run	Free	Clear
					4	DB	DB	Retention
					5	Free Run	DB	Retention
					6	DB	Free	Retention
					7	Free Run	Free	Retention
				DB: Activation of dynamic brake
68	Error response	0 – 3	–	The parameter sets driving conditions during deceleration or following
	action			stop, after any of protective functions of the driver has been activated and
				alarm has been generated.
					Setting	Driving Conditions		Content of Deviation
					value	During Deceleration	After Stopped	Counter
					[0]	DB	DB	Clear
					1	Free Run	DB	Clear
					2	DB	Free	Clear
					3	Free Run	Free	Clear
				(DB: Activation of dynamic brake)
				See also “When Abnormality (Alarm) Occurs (Serve ON Command State)”
				of the timing chart, Preparations volume on page 41.
69	Sequence at	0 – 7	–	• The parameter sets:
	Servo-OFF	[0]			1) Driving conditions during deceleration or after stop
					2) Processing to clear the deviation counter
					following Servo off (SRV-ON signal: CN X5 29-pin turns On ‡ Off).
				• A relationship between setting of Pr69 and driving conditions/deviation
					counter processing conditions is similar to that of Pr67 (Sequence at
					Main Power Off).
				• See also “Serve On/Off Operation When the Motor Stops” of the timing
					chart of Preparations volume on page 42.
