T1: 6 msec or more; time after selecting/entering a command position until the start input turns ON
(The scan time of the host controller must be considered.)
Each command position must be input after the position complete output has turned ON for the movement to the
previous position.
z Conditions for determining completion of push & hold operation
Push & hold operation is deemed to have completed upon elapse of the time set by parameter No. 6 (Push
completion judgment time) after the motor current reached the current-limiting value set in the “Push” field of the
position table.
Set an appropriate value by considering the material and shape of the work part, and so on.
The minimum setting unit is “1 msec,” while the maximum value is “9999 msec.” The factory setting is “255 msec.”
(Note) The chart below explains how completion of push & hold operation is determined if the work part shifted
during the judgment and the current has changed as a result, based on a judgment time of 255 msec.
If the motor current remains at or above the push current for 200 msec and then drops below this level for 20 msec,
the count will decrease by 20. When the push current is reached again thereafter, counting will start from 180. If the
motor current remains at or above the push current for 75 msec, the count will increase to 255 and thus push & hold
operation will be deemed to have completed.
In total, 295 msec was required for the judgment.
