Emergency Stop Operation/Deceleration-and-Stop Operation

Emergency Stop Operation/Deceleration-and-Stop Operation
An active operation can be interrupted and canceled.

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.
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.

Command

Transistor ON
Assign the emergency stop or deceleration-and-stop to the multifunction input 1 (EX-IN1: CN X5
Pin 22) or multifunction input 2 (EX-IN2: CN X5 Pin 25) by SV.Pr5A (multi function input 1 signal
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
canceled and a stop operation starts. The signal logic can be changed by SV.Pr59 (multi function
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
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
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.

Description
[Operation Setting]
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.
