8.9.4 Motor Holding Brake Connection

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).
Brake voltage supply by using 24 V ±10% auxiliary voltage supply of the drive on X10. Min-
imum and maximum brake current see Electrical Data (➜ # 34) respectively (➜ # 36).
AKD2G offers motor brake outputs on connectors X1 and X2. The outputs can be mapped to
the required axis with WorkBench.
Serious injury could result when the load is not properly blocked. The internal brake function
does not ensure functional safety.

X1 Primary motor brake axis 1 or secondary brake for axis 2
X2 Primary motor brake axis 2 or secondary brake for axis 1
No functional Safety!
Functional safety, e.g. with hanging load (vertical axes), requires an additional brake,
controlled e.g. from the other axis or externally from a safety controller. The brakes can
be mapped to an axis with WorkBench.
The Hardware Enable does not initiate a controlled stop but switches off the power stage
immediately.
Set parameter AXIS#.MOTOR.BRAKEIMM to 1 with vertical axes, to apply the brake
immediately after faults or Hardware Disable.
