Information information
Braking resistor overload protection parameter settings
Failure to observe the following information may damage the resistor.
The drive's software contains an overload protection function for a braking resistor. On Digitax ST this function is enabled at default to
protect the internally mounted resistor. Below are the parameter settings.
CAUTION
Table 12-5 Defaults for Pr 10.30 and Pr 10.31
Pr 10.30 - Full power braking time
Pr 10.31 - Full power braking period
For more information on the braking resistor software overload protection, see Pr 10.30 and Pr 10.31 full descriptions in the Advanced
User Guide.
If the internally mounted braking resistor is to be used at more than half of its average power rating then the drive's cooling fan must be
at full speed, controlled by setting Pr 6.45 to On (1).
