ABS (Absolute Coordinate)
- CIMON (Unlicensed)
Position control by absolute coordinate is performed based on the address designated in the origin point address. Object moves from start address to target address.
Direction of movement is determined by the sign (+, -) and pulse output method of the movement amount.
a) Pulse Output Method: High Active Mode
When the movement direction is plus (+): Forward Positioning
When the movement direction is minus (-): Backward Positioning
b) 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 PLC-S moves forward and stops at '5000.' The overall movement amount is '5000 – 1000 = 4,000.'
Positioning Special Module (PLC-S) Configuration
How to configure X Axis Parameter
The default setting for the X Axis is as follows.
Item | Setting Value | Description |
Pulse Output Method | High Active | Select a desired pulse output type |
Bias Speed(PPS) | 100 | Initial speed for the positioning |
Speed Limit(PPS) | 1,000 | Maximum speed for the positioning |
Acc/Dec Time 1 | 1,000 | The time taken for the speed to increase or decrease from 0 to the speed limit |
Acc/Dec Time 2 | 1,000 | |
Acc/Dec Time 3 | 1,000 | |
Acc/Dec Time 4 | 1,000 |
How to configure X Axis Position Data
Position Data No. | Control Pattern | Interpolation | Acceleration Time | Deceleration Time | Control Code | Dwell Time | Operation Speed | Target Address |
1 | Single Step | Non-Interpolation | No. 1 | No. 1 | ABS | 0 | 1,000 | 5,000 |
How to write a Scan Program
For the initial run, the current position value is configured as 1,000.
POSCTRL command is used.
When M00 Bit is turned on (by Shift + Enter), ABS position data will be executed.
When M00 Bit is turned on (by Shift + Enter), ABS position data will be executed.
