9.11.3 Functionality
The brake function must be enabled through a parameter. The diagram below shows the tim-
ing and functional relationships between the controlled stop signal, speed,and braking force.
All values can be adjusted with parameters; values in the diagram are default values.
The speed setpoint of the drive is internally driven down an adjustable ramp (CS.DEC) to 0 V.
With default values the output for the brake is switched on when the speed has reached
120 rpm (CS.VTHRESH) for at least 6 ms (CS.TO). The rise (t
brH
) and fall (t
brL
) times of the
holding brake that is built into the motor are different for the various types of motor.
