Panasonic A4P Series Emergency Stop Operation/Deceleration-and-Stop Operation, And-stop, 125

For emergency stop: ￿

Decelerates according to 16.Pr No. 49 (deceleration time at emergency stop).￿ For deceleration-and-stop: ￿ Decelerates according to the decelera- tion time specified in an operation mode before deceleration starts.

Emergency Stop Operation/Deceleration-and-Stop Operation [Operation Setting]

Emergency Stop Operation/Deceleration-and-Stop Operation

An active operation can be interrupted and canceled.

Emergency stop : An operation stops in a deceleration time specified by a special parameter.

Deceleration-and-stop : An operation stops in a deceleration time specified in an operation mode before the start of deceleration.

	Procedure					Description
￿		Assign the emergency stop or deceleration-and-stop to the multifunction input 1 (EX-IN1: CN X5
(1)￿ Assignment of emergency		Pin 22) or multifunction input 2 (EX-IN2: CN X5 Pin 25) by SV.Pr5A (multi function input 1 signal
￿	stop/deceleration-and-stop￿	selection) or SV.Pr5C (multi function input 2 signal selection).￿
	￿
￿	￿	By connecting (closing) the open multi function input 1/2, to which the emergency stop or
￿	￿	deceleration-and-stop is assigned, into COM– when the motor is running, an active operation is
￿	Start of emergency	canceled and a stop operation starts. The signal logic can be changed by SV.Pr59 (multi function
(2)￿ stop/deceleration-		input 1 signal logic) or SV.Pr5B (multi function input 2 signal logic).￿
		• For emergency stop: An operation decelerates according to 16.Pr49 (deceleration time at
￿	and-stop￿
￿	￿		emergency stop). If a set value is			“0”, an operation stop in the deceleration time “0”.￿
￿	￿	• For deceleration-and-stop: An operation stops in a deceleration time specified in an operation
￿	￿		mode at the start of deceleration.￿
￿	￿	When a stop operation has completed, a transistor of the in-operation signal output (BUSY: CN X5
(3)	Stop confirmation	Pin 28) turns ON again. Then, the current position output (P1OUT to P32OUT: CN X5 Pin 29, 30,
		31, 32, 33 and 34) keeps the state before the deceleration.

*Positioning completion output/in-deceleration output (COIN/DCLON: CN X5 Pin 27)

In SV.Pr64 (output signal selection), you can select COIN or DCLON to be output. For the timing of turning the transistor ON/OFF, refer to the diagram above.

Setting Operation

Caution

1)Even if the multifunction input 1/2 (EX-IN1/EX-IN2) is returned to the OPEN state, the deceleration is not canceled and the stop operation continues. Return the multi function input to the previous state after the emergency stop or deceleration-and-stop, specify a point just like as a normal step operation and connect (close) the open strobe signal input (STB: CN X5 Pin 24) to COM–. Then, movement to the point starts.

2)When you input a stop signal during a homing operation, retry the homing operation from the beginning.

3)If the emergency stop and deceleration-and-stop are assigned to the multifunction input 1 and 2 (EX-IN1 and EX-IN2), respectively, and those are input simultaneously, the higher priority is given to the emer- gency stop.

4)If the emergency stop is input during deceleration by the deceleration-and-stop, an operation stops in the deceleration time “0”.

5)When the emergency stop or deceleration-and-stop is input, the start of step operation, jog operation and homing operation (strobe signal input (STB) ON) is ignored.
