Positioning speed
Actual deceleration time
Set deceleration time
(2) Types of stop processes
The operation can be stopped with deceleration stop, sudden stop or immediate
stop.
(1) Deceleration stop
The operation stops with "deceleration time 0 to 3" ( Pr.9 , Pr.29 , Pr.30 ,
Pr.31 ).
Which time from "deceleration time 0 to 3" to use for control is set in positioning
data ( Da.4 ).
(2) Sudden stop
The operation stops with " Pr.37 Sudden stop deceleration time".
(3) Immediate stop
The operation does not decelerate.
The AD75 immediately stops the position/speed command output, but the
operation will coast for the droop pulses accumulated in the servo amplifier's
deviation counter.
