Name
Maintenance signal output 1 to 3
Description
Appears when the inverter's cumulative energization time reaches or exceeds the parameter set
value. Set the time until the MT is displayed using Pr. 504 "Maintenance timer 1 warning output
set time" (MT1), Pr. 687 "Maintenance timer 2 warning output set time" (MT2), and Pr. 689
"Maintenance timer 3 warning output set time" (MT3).
MT does not appear when the settings of Pr. 504, Pr. 687, and Pr. 689 are initial values (9999).
Check point
The set time of maintenance timer has been exceeded. (Refer to page 5-227.)
Corrective action
Take appropriate countermeasures according to the purpose of the maintenance timer setting.
Setting "0" in Pr. 503 "Maintenance timer 1", Pr. 686 "Maintenance timer 2", and Pr. 688
"Maintenance timer 3" clears the indication.
MT appears for all of MT1, MT2 and MT3 on the FR-PU07.
