Motor Overload Estimate
(oL1)
Shows the value of the motor overload detection accumulator. 100% is equal
to the oL1 detection level.
10 V: 100% 0.1%
U4-17
(7D9H)
Drive Overload
Calculations (OL2)
Displays the level of the drive overload detection (oL2). A value of 100% is
equal to the oL2 detection level.
10 V = 100% 0.1%
U4-18
(7DAH)
Speed Reference
Selection Results
Displays the source for the speed reference as XY-nn.
X: indicates which reference is used:
1 = Reference 1 (b1-01)
Y-nn: indicates the reference source
0-01 = Digital operator
1-01 = Analog (terminal A1)
1-02 = Analog (terminal A2)
2-02 to 8 = Digital Inputs (d1-02 to 8)
3-01 = MEMOBUS/Modbus communications
4-01 = Communication option card
