Mitsubishi Electronics QD75P, QD75D user manual Pr.14 Software stroke limit selection, Md.31

5 DATA USED FOR POSITIONING CONTROL

MELSEC-Q

1)Generally, the OP is set at the lower limit or upper limit of the stroke limit.

2)By setting the upper limit value or lower limit value of the software stroke limit, overrun can be prevented in the software. However, an emergency stop limit switch must be installed nearby outside the range.

3)To invalidate the software stroke limit, set the setting value to "upper limit value = lower limit value". (The setting value can be anything.)

4)When the unit is "degree", the software stroke limit check is invalid during speed control (including speed-position switching control, position-speed switching control) or during manual control.

Command in-position width

Set the remaining distance that turns the command in-position ON. The command in-position signal is used as a front-loading signal of the positioning complete signal. When positioning control is started, the "command in-position flag" (3rd flag

from right) in "

Status" turns OFF, and the "command in-position flag" turns

ON at the set position of the command in-position signal.
