When the external interrupt input turns ON, the Deceleration Stop value is
compared to the count in the error counter. If the count in the error counter is
greater than the Deceleration Stop value, the Deceleration Stop value is not
used and the system will stop after the positioning system has moved by the
pulse count already in the error counter. This occurs when the jogging speed
is high (creating a high count in the error counter) and the Deceleration Stop
value is low.
When jogging speed is high, and
number of set pulses is low.
External interrupt input
JOG operation
If the count in the error counter is less than the Deceleration Stop value, then
the count in the error counter is increased to equal the Deceleration Stop val-
ue and the system will stop after the positioning system has moved by the
number of pulses designated for the Deceleration Stop.
When jogging speed is low, and
number of set pulses is large.
External interrupt input
JOG operation
Therefore, if you want to stop as soon as possible for external interrupts, set
the Deceleration Stop value low in comparison to the jogging speed. If you
want to ensure that a specific distance is moved after receiving an external
interrupt, set the Deceleration Stop value high in comparison to the jogging
speed.
This parameter is used to limit the error counter capacity while the emer-
gency operation stop function of the Position Control Unit is active. Only
while the emergency operation stop function is active, the error counter
capacity will be set to the value that has been preset, in which case no accu-
mulated value exceeding the measured value will be stored.

Range: 1 to 9,999 pulses
(Default: 0)
If the value is set to 0, the error
counter capacity will be set to 32,767.
If the value is changed to 1 to 9,999
from 0, the value cannot be reset to 0.

To move the object controlled by the Position Control Unit manually, for
example, use this function so that the servo free function will be active while
the emergency stop input is ON to move the object by hand and then disable
the servo free function, in which case the object will not move quickly to
return to the previous position.
