Motor control (MCTRL)
Braking operation/braking energy management
The way in which the different brake procedures work is demonstrated schematically in
the following illustration:

Graph of the effective speed setpoint and the DC bus voltage during braking
Tip!
If it is possible to dispense with exact adherence to the deceleration ramp in simple
applications, selection of a braking method without an external brake resistor
enables costs to be reduced due to the avoidance of having to use a brake resistor .
• For the delay time, select a value as high as possible if you are not using an
external brake resistor, and use the S-shaped ramp if possible.
The "inverter motor brake" function serves to implement an effective braking
torque of 10 ... 20 % of the rated motor torque.
Use of the brake resistor (
= "0: Brake resistor")
Stop of deceleration (
= "1: HlgStop")
Inverter motor brake (
= "3: FU_ HlgStop)
