DetailsNameRelay No.
・ When communication is used for controlling operation, value of P003 is set to "6" or "7".
・ When a fault occurs in the inverter, the fault will not be reset even if the run command is turned
to "OFF" ("0").
Fault reset command (DT253) is used for fault reset.
・ SW1～SW5 functions differ depending on settings.
"DT237: Storage without frequency setting memory"
"DT238: Storage with frequency setting memory"
・ When storing with frequency setting memory (DT238), the set frequency is written in non-volatile
memory inside the inverter. However, its maximum writing times is 100,000 times. If it is necessary
to change frequency settings frequently, storage command without memory (DT237) should be set to.
・ When communication control is used for setting frequency, value of P003 is set to "6" or "7".
・ When a fault occurs in the inverter, no setting can be performed.
・ When writing into DT237, it will not be stored in the memory inside the inverter.
12-9.2 Supplementary Explanation of Communication Control/Command Function
"DT 253: Fault reset command"
・ The fault reset activates by writing "H9696" in the register No. 253.
・ The usable data is "H9696" only.
・ This command is ignored when the inverter is operating properly.
"DT253: Emergency stop command"
・ The emergency stop activates by writing "H9696" in the register No. 255.
・ The coast-to-stop function is performed displaying "AU" in the same operation as the external
fault input.
・ The usable data is "H9696" only.
