Description
Selects the rate of use (in %) of the
regenerative braking resistor per 100 s
intervals, range is 0.0 to the value
calcurated by the inverter with b097.
If the connected register's allowable range is
narrow than above range,
the register's range is prior.
0%: Function disabled
>0%: Enabled, per value
Three option codes:
Disable
Enable during run only
Enable always
If DC Voltage > b096,
the register consume. regeneration power.
Range is:
330 to 380V (200V class)
660 to 760V (400V class)
Set the value of the register connected to the
inverter.By this setting, b090's upper limit as
the inverter hardware is calcurated
automatically.So, you can focus the usage
ratio as the connected register.
Range is minimum connectable register
