6.1.1
Purpose of the function
The "24 V back-up on power failure" function is used to stop in a controlled manner the
masses moved in a mechanical system (e.g. robot arm). For this purpose the DC link in
the 24 V switched-mode power supply (24 V SMPS) is coupled to the DC links in the
axis controllers (DC Link +/-). During braking of the drive axis, energy is generated that
charges the DC links in the axis controllers. Using this additional energy the 24 V control
supply can be maintained for longer.
6.1.2
Function description
Coupling takes place immediately after precharging. For trouble-free operation, the
mains supply to the switched-mode power supply (X7) is then to be disconnected
(see Figure, contact 3.2). For this purpose the parameter 270-0 in the firmware is to be
set to the value "16".
NOTE:
The total power drawn from the internal 24 V power supply unit must not
exceed Pv = 240 W max. for this operating case!
CAUTION!
DAMAGE TO THE DEVICE DUE TO ERROR IN THE WIRING!
x
Carelessness may result in significant damage.
Operation of these devices with 3 x 230 V mains supply is not allowed for the "24 V back-up on
power failure" variant.
