Chapter 6 Applied Instructions Explanation 1. This instruction is available for PLC with FW V1.02.00 or later. 2. Module sets the serial number of modules at the right of the PLC. The first one is number 1, the second one is number 2 and so on. Whatever modules at the right of the PLC must be numbered. The maximum number is 8. The instruction is exclusive to the PU modules at the right of the PLC. If the specified module is not a PU module, the error flag Error will change to ON. 3. Axis sets the output axis number for the specified PU module. The setting values 1~2 represent the axis1~axis2 output of the specified PU module respectively.
If the PU module has no corresponding axis number for output, the error flag Error will change to ON. 4. Mode sets a homing mode. The explanation of modes is shown in the following table. 6_ 6-431 Mode value Function description Input point used Remark with other setting together 0 Directly clear current position to 0. None 1 Specify the point where DOG point is touched as the original point; the axis starts to go toward the negative direction and then stops after leaving the DOG point position.
DOG Use the setting in HWCONFIG 2 Specify the point where DOG point is touched as the home point; the axis starts to go toward the negative direction and then stops after leaving the DOG point position. DOG Use the setting in HWCONFIG 3 After the behavior of when Mode=1 is finished, seek the set number of Z phases. DOG and Z phase input Use the setting in the DPUCONF instruction 4 After the behavior of when Mode=2 is finished, seek the set number of Z phases. DOG and Z phase input Use the setting in the DPUCONF instruction 5 After the behavior of when Mode=1 is finished, output the specified number of output pulses.
DOG Use the setting in the DPUCONF instruction 6 After the behavior of when Mode=2 is finished, the PLC outputs the specified number of output pulses. DOG Use the setting in the DPUCONF instruction 7 The behavior of when Mode=1 + positive and negative limits DOG, negative limit, positive limit Use the setting in HWCONFIG
