9.11 Motor Brake Connection (X2, X15, X16)
A 24 V holding brake in the motor can be controlled directly by the drive. For proper function,
check voltage drop, measure voltage at brake input and check brake function (on and off).
WARNING
No functional Safety!
Serious injury could result when the load is not properly blocked. This
function does not ensure functional safety.
Functional safety, e.g. with hanging load (vertical axes), requires an
additional mechanical brake which must be safely operated, for
example by a safety control.
The Hardware Enable (connector X8 pin 4) does not initiate a con-
trolled stop but switches off the power stage immediately.
Set parameter MOTOR.BRAKEIMM to 1 with vertical axes, to apply the
brake immediately after faults or Hardware Disable.
