Using Intelligent Output Terminals Section 4-6
4-6-14 Electronic Thermal Warning Signal Output
You can configure this function so that the inverter outputs a warning signal
before the electronic thermal protection operates against motor overheat. You
can also set the threshold level to output a warning signal with the electronic
thermal warning level setting (
C061).
To output the warning signal, assign function "
13 (THM)" to one of the intelli-
gent output terminals [11] to [12], or to the relay output terminal.
4-6-15 External Brake Related Output Signals
These signals are used with brake control function.
To output the warning signals, assign function "
19 (BRK)" and "20 (BER)" to
the intelligent output terminals [11] and [12], or to the relay output terminal.
Refer to SECTION 3 Configuring Drive Parameters on page 59 detailed
explanation of the brake control function.

Valid for inputs: 11, 12, AL0 - AL2
Required settings: C061
Notes:
• 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.
