Note 1: Connection when using an MCCB with a top coil instead of an MC.
Note 2: A depression transformer is required for 400V models but not for 200V models.
[Parameter setting]
Title Function Adjustment range Example of setting
RD Dynamic braking selection
:Deselect
:Select (bracking resistance
overload detect)
: Select (bracking resistance
overload not detect)
RDT Dynamic braking resistance ~Ω Any value
RDER
Allowable continuous braking
resistance
~kW Any value
(When the thermal braking resistor option is not used, be sure to set the parameters RDT and RDER properly
for overload protection.)
* As a last resort to prevent fire, be sure to connect a thermal relay (THR). Although the inverter has a means of
preventing overload and overcurrent to protect the braking resistor, the thermal relay is activated in case the
protection function fails to work. Select and connect a thermal relay (THR) appropriate to the capacity (wattage)
of the braking resistor.
- Warning -
In the above circuit, the MC in the main circuit is turned off if an inverter's protective function is activated, and
consequently no trip message is displayed. The inverter recovers from a trip if it is turned off. So, check the trip
history record after turning off the inverter and then on again. ⇒ Refer to Section 8.2.1.
To prevent a trip condition from being cleared by turning off the power and then on again, change the setting of the
inverter trip retention selection parameter H. ⇒ Refer to Section 6.33.2.
