67-Timed Overload Trip - Sets the amount of overload that will cause a Timed Overload fault (F20) to occur. A Timed Overload fault will occur when the output current reaches 150% of the set value for 1 minute. The Timed Overload Trip is active between 30-100% of the Inverter Rated Current (03-Rated Current) parameter value. The value of the Timed Overload Trip parameter should be calculated by the following formula:
Value of Parameter 67 + Motor FLA X 100 03±Rated Current
The range of adjustment is from 0 to 100%. The factory setting is 0%. The Timed Overload Trip for various output frequencies is shown in the following figure:
Trip Time (Min)
70-Analog Output Scale - Allows scaling of the analog meter output at control terminal MET to be more or less than the normal 0-10 VDC level. The factory setting is for 10 VDC output at full inverter output. The adjustable range is 0-255 in digital units.
