FR-A700 EC

6 - 407

Reset limit

Setting can be made for the 02160 or more.

You can set Pr. 75 to disable reset operation until the thermal cumulative amount reaches "0"
when a thermal trip (THM, THT) or an over current trip (OC1 to OC3) occurs consecutively twice.

When Pr. 75 = "100 to 103, 114 to 117", reset limit is made valid.

NOTE

When the power-on reset (no control power is supplied) is made, the thermal cumulative
amount is cleared.
