2 Functions of Devices in DVP-PLC The Master PLC has to be SA/SX/SC/EH2/SV/EH3/SV2 series MPU, and the Slave AC motor drive can be any VFD series models except VFD-A. The Slave can also be Delta temperature controller DTA, DTB, Delta servo ASDA and so on which are compatible to Modbus protocol. Maximum 16 devices are connectable to the LINK. See the tables of special M and special D for the starting ID of Slave to be read/written and the number of data to be read/written. Function Group Enabling the instruction DICF to execute the constant speed/final output section Number M1528~M1529 Contents: 1. M1528 On:
Enabling the instruction DICF to execute the constant speed output section M1529 On: Enabling the instruction DICF to execute the final output section If users want to use this special output function, they have to use M1528/M1529 with DVSPO/DICF. Please do not enable the two flags simultaneously. 2. The instruction format is DVSPO S 1 S 2 S 3 D . The instruction is a 32-bit instruction. S 1 is the target frequency of output, S 2 is the target number of pulses, S 3 indicates the gap time and the gap frequency, and D is the pulse output device. (If S 2 is K0, there will be no limit on the number of output pulses, and pulses will be output until the final output section is set. 3.
The instruction format is DICF S 1 S 2 D . The instruction is a 32-bit instruction. S 1 is the target frequency to 4. If users do not need to set the target number of pulses when DVSPO enables output, they can set S 2 to K0, and be changed, S 2 indicates the gap time and the gap frequency, and D is the pulse output device. then set the target frequency of the output, the gap time, and the gap frequency. If users want to end the output, they can use DICF and M1529 to execute the final output section. After the execution of the final output section is complete, DVSPO sill set the completion flag. (Please refer to example 1.) 5.
When DICF is used with M1529 to execute the final output section, S 1 is the target frequency of output ( S 1 can not be modified by an E device or an F device), and the 32-bit value indicated by S 1 +2 is the number of pulses which need to be output in the final section. For example, if S 1 is D100, the 32-bit value in (D101, D100) is the target frequency of output, and the 32-bit value in (D103, D102) is the number of pulses which need to be output in the final section. After M1529 successfully enables the final output section, M1529 will be reset to Off 6. In the final output section, DICF carries out acceleration/deceleration operations according to the automatically.
acceleration/deceleration time specified by the axes (the parameter indicated by S2 is not used), and the current output speed increases/decreases until the number of pulses required is reached. DVSPO sets the completion flag. (Please refer to the examples in 1.1~1.2 in example 1 for more information.) 7. If the number of pulses in the final section is not sufficient for the acceleration/deceleration output set by users, DICF will automatically change the acceleration/deceleration operation to the default acceleration/deceleration operation so that the target number of pulses in the final output section can be reached. 8.
When DICF is used with M1528 to execute the constant speed output section, S 1 is the target frequency of output ( S 1 can not be modified by an E device or an F device), and the 32-bit value indicated by S 1 +2 is the number of pulses which need to be output in the constant speed output section. For example, if S 1 is D100, the DVP-PLC Application Manual 2-139
