Note 1: The data in Rating above refer to the resultant resistance capacities (watts) and resultant resistance
values (Ω).
Note 2: Braking resistors for frequent regenerative braking are optionally available. For more information,
contact your Toshiba distributor.
Note 3: Type-form of “PBR-” indicates the thermal fuse”. Type-form of “PBR7-“ indicates the thermal fuse
and thermal relay.
Note 4: VFNC3E-4055P and VFNC3E-4110P:
Default setting of parameter f308 and f309 is for previous Toshiba breaking resistor PBR3-.
Set parameter
f308 and f309 to following table value.

VFNC3E-4015P to 4037P and VFNC3E-4075P:
The default setting values of parameter
f308 and f309 are applied to braking resistor option.
3) Minimum resistances of connectable braking resistors
The minimum allowable resistance values of the externally connectable braking resistors are listed in the
table below.
Do not connect braking resistors with smaller resultant resistances than the listed minimum allowable
resistance values.
