Power supply in order (UD)
The UD contact acknowledges that the power supply is in working order.
It opens in the event of the following faults:
•
mains
fault
•
DC bus voltage is smaller than the permissible minimum value
(HVR: 680 V, HVE: 80% of U
Netz
)
•
when switching off K1
If the installation requires that the drives be shutdown with position control
in the event of a mains fault, then the installation control must evaluate
the UD contact and shut down the drives in a controlled fashion.
Pre-warning (VW)
The pre-warning contact is opened, if the cooling unit temperature in the
power supply unit is too high or a critical value is reached in an additional
component. The mains contactor in the power supply unit interrupts the
power supply after 30 seconds and the Bb1 contact opens.
Note:
If the installation requires that the drives are shut down in a
position controlled fashion if there is a fault in the unit, then the
drives must be shutdown within 30 seconds.
Bleeder pre-warning contact (BVW)
The bleeder pre-warning contact only exists in the HVE power supply
units. The bleeder pre-warning contact opens if continuous regenerated
power exceeds 80% of the continuous bleeder power. If the bleeder
power continues to rise, then the mains contactor stops the HVE power
supply unit and the Bb1 contact opens.
