Braking operation without additional measures

Decelerating small masses
To decelerate small masses, the "DC injection brake DCB" functions can be parameterised.
DC−injection braking enables a quick deceleration of the drive to standstill without using
an external brake resistor.
Code C00036 can be used to select the braking current.
ƒ
The maximum braking torque to be realised by the DC braking current amounts to
ƒ
approx. 20 ... 30 % of the rated motor torque. It is lower compared to braking action
in generator mode with external brake resistor.
Automatic DC−injection braking (Auto−DCB) improves the starting performance of
ƒ
the motor when the operation mode without speed feedback is used.
Further information on the relevant parameters can be obtained from the software
manual.
