The specifications given for each resistor model also include the mean power to be dissipated and the max.
operating time, depending on the inverter voltage class.
Based on these values, parameters C67 and C68 (IFD SW) OR C59 and C60 (VTC SW) (concerning braking
features) in the Resistor Braking menu can be set up. (See relevant section in the Programming Manual).
The max. operating time set in C68 (IFD SW) or C60 (VTC SW) is factory-set in order not to exceed the
allowable time for each resistor model (see section below).
Parameters C67 (IFD SW) or C59 (VTC SW) represent the max. duty-cycle of the resistor and must be set to a
value lower than or equal to the value stated in the dimensioning table (see sections above).
DANGER Braking resistors may reach temperatures higher than 200°C.
CAUTION
For parameters C67, C68 (IFD SW) or C60 (VTC SW), do not set values exceeding
the max. allowable values stated in the tables above. Failure to do so will cause
irreparable damage to the braking resistors; also, fire hazard exists.
CAUTION
Braking resistors may dissipate up to 50% of the rated power of the connected
motor; use a proper air-cooling system. Do not install braking resistors near heat-
sensitive equipment or objects.
