Stop operation under position control (Pr.464, Pr.535)
(1) Sudden stop (X87 signal)
When the X87 signal (position control sudden stop signal) is assigned to the input terminal, the operation stops according
to the deceleration time slope set by
Pr.464 Position control sudden stop deceleration time
by turning OFF the signal
(normally closed input). However, when the deceleration time set in
Pr.464 Position control sudden stop deceleration time
is
longer than that set by the current position control command, the deceleration time slope set by the current position
control command is applied. After the operation is stopped, turning ON the X87 signal starts position control again. To
input the X87 signal, set "87" in any of
Pr.178 to Pr.184 (input terminal function selection)
to assign the function to a terminal.
When the ones digit of the set value in
Pr.535 Position control terminal input selection
is "0", the normally open input is
applied and the operation is stopped by turning ON the X87 signal.
While position control is being performed, the operation can be stopped via input terminals.

Position control sudden stop
deceleration time
0.01s
0.01 to 360s
Set the deceleration time when the operation is
stopped by inputting the sudden stop signal, forward
stroke end signal, or reverse stroke end signal.
Set the basis of deceleration time in
Pr.20 Acceleration/
deceleration reference speed
. Set the speed change time
from
Pr.20
to "stop" as the deceleration time.

The input logic can be selected for X87, LSP, and LSN.
Normally open: The operation is stopped when the
contact between SD and each signal is closed.
Normally closed: The operation is stopped when the
