AKD-N Installation | 9 Electrical Installation
9.9 Motor Brake Connection (X4)
A 24 V holding brake in the motor can be controlled directly by the drive. The brake only
works with sufficient 24 V voltage level. Check voltage drop, measure the voltage at brake
input and check brake function (brake and no brake). Maximum current for the motor brake is
1 A with AKD-N00307 and 1.5 A with AKD-N00607 or AKD-N-N01207.
The stand-by power supply from AKD-C limits the number of brakes in the system. Observe
the projecting hints for system topology and limits in the
Projecting Guide
.
CAUTION
No Functional Safety
Serious injury could result when a suspended load is not properly
blocked. Functional safety requires and additional, external mechanical
brake, operated by a safety controller.
Add a safe mechanical blocking (for instance, a motor-holding brake).
Set parameter MOTOR.BRAKEIMM to 1 with vertical axes, to apply the
motor holding brake immediately after faults or Hardware Disable.
The brake function must be enabled and configured with parameter using WorkBench, for
details refer to the online help.
Single cable hybrid cable and dual cable motor power cable use two wires for motor holding
brake connection.
