8.1 Braking operation without additional measures
Decelerating small masses
To decelerate small masses, the ”DC injection brake DCB” functions c an be parameterised.
DC-injection braking enables a quick deceleration of the drive to standstill without using
an external brake resistor.
ƒ Code C00036 can be used to select the braking current.
ƒ The maximum braking t orque to be realised by the DC braking current amounts to
approx. 2 0 ... 30 % of the rated motor torque. It is lower compared to braking action
in generator mode with external brake resistor.
ƒ Automatic DC-injection braking (Auto-DCB) improves the starting performance of
the motor when the operation mode without speed feedback is used.
Further information on the relevant parameters can be obtained from the software
manual.
