Each drive is able, by using terminals 26 and 27, to control one or more
external braking units. The drive will act as Master and the external brake units
must be configured as Slave.
In this way it will be possible to utilize the internal I
2
t protection (see chapter 6,
B0I STARTUP / Drv & Mot config / BU olvd menu).
If more than one BU is used, each BU shall be connected to a single resistor. All
braking units shall be the same models and have same type resistors.
