FEED
1)
Before executing the FEED command, the current coordinate is cleared to zero (0) and then
the object moves (positioning control) by the specified movement amount.
2)
Direction of movement is determined by the sign (+, -) and pulse output method of the
movement amount.
Pulse Output Method: High Active Mode
When the movement direction is plus (+): Forward Positioning
When the movement direction is minus (-): Backward Positioning
Pulse Output Method: Low Active Mode
When the movement direction is plus (+): Backward Positioning
When the movement direction is minus (-): Forward Positioning
*For instance,
If the start address is ‘1000’ and the target address is ‘5000,’ the current coordinate (1,000) is cleared to
zero (0) and then PLC-S moves forward and stops at ‘5,000’ according to the target address (as opposed
to ABS which stops at ‘5000’ and INC which stops at ‘6000’).
