User Manual of EM760 High-Performance Inverter F10.05=1: enable the master-slave communication function; F10.06=1: select current inverter as the host (only one inverter can be set as the host in a network); and select F10.07 as the variable to be synchronized. If it’s output current, set F10.07 = 5. ● The inverter is used as the slave is set as follows: F10.05=1: enable the master-slave communication function; F10.06=0: select the current inverter as the slave; Select one setting as the communication setting. IfF09.00=6 is set and the process PID is set separately (F00.05=10, F00.06=1), the slave inverter will be set to the host output current for PID adjustment.
You can set the receiving proportional coefficient (F10.08) to determine how the slave inverter receives data. If F10.08=0.80 is set, the final application data is “Recv (received data) * 0.80 (F10.08)”. For the application “PLC controller/HMI + inverter”, you can set F10.56=11 after debugging. Then all write data ofPLC communication will not be stored, which can avoid damage to the memory. If you need parameter settings and power-down storage, set F10.56=0 first. F10.61=0: During the Modbus communication with the upper computer, both read and write parameters will be returned to the upper computer. F10.61=1:
During the Modbus communication with the upper computer, the read parameters will be returned to the upper computer, while the write parameters will not. F10.61=2: During the Modbus communication with the upper computer, both read and write parameters will not be returned to the upper computer. This can improve the communication efficiency. 167 Function code Function codename Parameter description Unit Default setting Attribute F10.56 Options of 485 EEPROM writing 0-10: default operation (for commissioning) 11: writing not triggered (available after commissioning) 0 O Function code Function codename Parameter description Unit Default setting Attribute F10.61 SCI response option 0:
