Fire mode operation voids the product warranty. To test fire mode not to increase the fire mode
operation count at ADV-83, set ADV-
80 to “2

Fire Test”
and operate the inverter.
If the multi-function terminal input set
to “51
(Fire Mode)
” is on
when ADV-83 is set to
“1
(Fire

”
, the count value set at ADV-83 is increased by 1.

Dynamic Braking (DB) Resistor Operation
Reference Voltage
Depending on the capacity, the iS7 series is divided into models with a braking resistor circuit
integrated inside the inverter, and models that require an external braking unit to be installed.
The inverters rated between 0.75
–
22 kW have the built-in braking model (except for the brake
resistor), and the inverters rated above 30 kW require an external braking unit. Therefore, the
reference voltage setting function for the braking resistor is necessary for inverters rated
below 22 kW.

: This is the operation reference voltage for the braking resistor. The
braking resistor operates when the DC link voltage exceeds the reference value.
The initial value for 200 V-type inverters is 390 V, and the initial value for 400 V-type inverters is
780 V.
For 200 V-type inverters, the reference voltage that stops the braking resistor is 10 V lower than
the operating voltage set at ADV-79. For 400 V-type inverters, the braking resistor stops if the
