Information
When using internal brake resistors, DIP switches (S1), No. 8
(S1)")
must be set to "on". This is important for activating a peak output limit for protecting the brake resistor.

1) maximum one-off within 10 s
2) In order to prevent non-permissible heating of the connection unit, the continuous power
is limited to 1/4 of the rated power of the brake resistor.
This also has a limiting effect on the energy consumption.
