3.11.5 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 size 1 and 2 this function is enabled at default to
protect the heatsink mounted resistor. Below are the parameter settings.
CAUTION
Full power braking time
Full power braking period
Full power braking time
Full power braking period
For more information on the braking resistor software overload protection, see the Advanced User Guide.
If the heatsink mounted braking resistor is to be used at more than half of its average power rating then the drive's cooling fan must be
set to full speed by setting Pr 6.45 to On (1).
See section 4.9.1 Heatsink mounted braking resistor on page 78 for the resistor specifications.

• Install the DC terminal cover grommets supplied in the accessory
box with the drive, to the cables. To ensure a good seal, the
grommets are a tight fit. Lubrication may be required to help install
the grommets to the cables.
• Terminate the cables with suitable crimps and connect to the BR
and DC2 terminals.
• Replace the terminal cover.
• See Figure 3-52 for through-panel mounting cut-out details.
• Pass the cables through the hole in the panel and install the hole
grommet.
• Install the mounting bracket.
