6-5-21 Word n+5 Bit 13: Jog Direction Bit (X-axis)
This bit determines which direction the axis will be moved in jog operation; it is
used together with the Jogging Bit. The status of the Jog Direction Bit is read
when the Jogging Bit is turned ON and has the following meaning.
ON: Negative direction (The direction that reduces the present value.)
OFF: Positive direction (The direction that increases the present value.)
The Jog Direction Bits for the Y axes (bit 13 in word n+7) operate in the same
way.
Signal The Jog Direction Bit settings have the following functions.
Signal Function
1 Sets the jog direction to negative.
0 Sets the jog direction to positive.
Note Refer to 6-5-20 Word n+5 Bit 03: Jogging Bit (X-axis) .
6-5-22 Word n+5 Bit 05: Current Position Preset Bit (X-axis)
This bit is used to set a new current position.
The new current position must be preset in the expansion data area.
The reference origin is automatically fixed after presetting the current position,
so it isn’t necessary to perform an origin search. Keep this bit ON until the Busy
Flag goes ON. This bit is available when the expansion data area is valid. This bit
is ignored if the Busy Flag is ON.
The current position preset operation can be performed in the servo-lock or ser-
vo-free status. This operation won’t be interrupted while in progress even if the
deceleration stop operation is executed.
The software limits are checked when this command is executed, and the cur-
rent position preset won’t be performed if there is an error.
The Current Position Preset Bits for the Y axes (bit 05 in word n+7) operate in the
same way.
Caution The present position presetting for the absolute encoder axis applies only to the
present position registered in the MC Unit. The present position registered in the
absolute encoder will not be preset. Therefore, the position will be automatically
updated to the present position registered in the absolute encoder when the
servo lock is executed next time.
Signal The current position preset operation is started when the Current Position Pre-
set Bit goes from OFF to ON (up-differentiation).
