【正文】 odule to go to a desired location. Turning on the EN bit enables the instruction. Ensure that the EN bit stays on until the DONE bit signals that the execution of the instruction has pleted. Turning on the START parameter sends a GOTO mand to the Position module. For each scan when the START parameter is on and the Position module is not currently busy, the instruction sends a GOTO mand to the Position module. To ensure that only one GOTO mand is sent, use an edge detection element to pulse the START parameter on. The Pos parameter contains a value that signifies either the location to move (for an absolute move) or the distance to move (for a relative move). Based of the units of measurement selected, the value is either a number of pulses (DINT) or the engineering units (REAL). The Speed parameter determines the maximum speed for this movement. Based of the units of measurement, the value is either a number of pulses/second (DINT) or the engineering units/second (REAL). POSx_LDOFF Instruction The POSx_LDOFF instruction (Load Reference Point Offset) establishes a new zero position that is at a different location from the reference point position. Before executing this instruction, you must first determine the position of the reference point. You must also move the machine to the starting position. When the instruction sends the LDOFF mand, the Position module putes the offset between the starting position (the current position) and the reference point position. The Position module then stores the puted offset to the RP_OFFSET parameter and sets the current position to 0. This establishes the starting position as the zero position. In the event that the motor loses track of its position (such as on loss of power or if the motor is repositioned manually), you can use the POSx_RSEEK instruction to reestablish the zero position automatically. Turning on the EN bit enables the instruction. Ensure that the EN bit stays on until the Done bit signals that the execution of the instruction has pleted. Turning on the START parameter sends a LDOFF mand to the Position module. For each scan when the START parameter is on and the Position module is not currently busy, the instruction sends a LDOFF mand to the Position module. To ensure that only one mand is sent, use an edge detection element to pulse the START parameter on. The Done parameter turns on when the module pletes this instruction. POSx_LDPOS Instruction The POSx_LDPOS instruction (Load Position) changes the current position value in the Position module to a new value. You can also use this instruction to establish a new zero position for any absolute move mand. Turning on the EN bit enables the instruction. Ensure that the EN bit stays on until the Done bit signals that the execution of the instruction has pleted. Turning on the START parameter sends a LDPOS mand to the Position module. For each scan when the START parameter is on and the Position module is not currently busy, the instruction sends a LDPOS mand to the Position module. To ensure that only one mand is sent, use an edge detection element to pulse the START parameter on. The New_Pos parameter provides the new value to replace the current position value that the Position module reports and uses for absolute moves. Based of the units of measurement, the value is either a number of pulses (DINT) or the engineering units (REAL). The Done parameter turns on when the module pletes this instruction. POSx_DIS Instruction The POSx_DIS instruction turns the DIS output of the Position module on or off. This allows you to use the DIS output for disabling or enabling a motor controller. If you use the DIS output on the Position module, then this instruction can be called every scan or only when you need to change the value of the DIS output. When the EN bit turns on to enable the instruction, the DIS_ON parameter controls the DIS output of the Position module. POSx_CLR Instruction The POSx_CLR instruction (Pulse the CLR Output) mands the Position module to generate a 50ms pulse on the CLR output. Turning on the EN bit enables the instruction. Ensure that the EN bit stays on until the Done bit signals that the execution of the instruction has pleted. Turning on the START parameter sends a CLR mand to the Position module. For each scan when the START parameter is on and the Position module is not currently busy, the instruction sends a CLR mand to the Position module. To ensure that only one mand is sent, use an edge detection element to pulse the START parameter on. The Done parameter turns on when the module pletes this instruction. POSx_CFG Instruction The POSx_CFG instruction (Reload Configuration) mands the Position module to read the configuration block from the location specified by the configuration/profile table pointer. The Position module then pares the new configuration with the existing configuration and performs any required setup changes or recalculations. Turning on the EN bit enables the instruction. Ensure that the EN bit stays on until the Done bit signals that the execution of the instruction has pleted. Turning on the START parameter sends a CFG mand to the Position module. For each scan when the START parameter is on and the Position module is not currently busy, the instruction sends a CFG mand to the Position module. To ensure that only one mand is sent, use an edge detection element to pulse the START parameter on. The Done parameter turns on when the module pletes this instruction. 指導(dǎo)教師評(píng)語(yǔ)： 簽名： 年 月 日
