5.1.8 Optimal Braking using Resistor

Dynamic braking is useful from maximum speed down to a certain fre-
quency. Below this frequency DC braking is to be applied as required. The
most efficient way of doing this is by using a combination of dynamic and
DC braking. See the illustration.

NB!

When changing from dynamic to DC braking, there will be a short period (2-6 milliseconds) with very low braking torque.

How to calculate optimum DC-brake cut in frequency:

5.1.9 Brake Cable

Max. length [m]: 10 m
The connection cable to the brake resistor must be screened/armoured. Connect the screen to the conductive backplate at the frequency converter and
to the brake resistor metal cabinet by means of cable clamps.

NB!

If Danfoss brake resistors are not used, it must be ensured that inductance for the brake resistor is low.
