Using Intelligent Output Terminals Section 4-6
4-6-7 Overload Advance Notice Signal
When the output current exceeds
a preset value, the [OL] terminal
signal turns ON. The parameter
C041 and C111 sets the overload
threshold. (Two thresholds can be
set.) The overload detection circuit
operates during powered motor
operation and during regenerative
braking. The output circuits use
open-collector transistors, and are
active low.

Valid for inputs: 11, 12, AL0 - AL2
Required settings: C041, C111
Notes:
• The default value is 100%. To change the level from the default, set C041 (overload
level) and/or C111 (overload level (2)).
• The accuracy of this function is the same as the function of the output current mon-
itor on the [FM] terminal (see Analog Output Operation on page 225).
• The example circuit for terminal [11] drives a relay coil. Note the use of a diode to
prevent the negative-going turn-off spike generated by the coil from damaging the
inverter's output transistor.
