Assignment
[1] axis 1 ... [6] axis 6
[7] external axis 1 ... [12] external axis 6
The values here can be read from a table and are dependent on the motor.

Assignment
[1] axis 1 ... [6] axis 6
[7] external axis 1 ... [12] external axis 6
The brake cools down again when the system is at standstill. The energy dissipated depends
on the cooling factor of the brake.
Example
The first external axis is driven by a motor of type D:
$BRK_COOL_OFF_COEFF[7]=33
