DKR Drive Controllers
DOK-DIAX03-DKR********-PR02-EN-P
The TVW contact opens with an overload of the internal optional
emergency brake resistor [or the external brake resistor (only DKR4.1)].
The K1NC contact is closed if the internal mains contactor has dropped
off. This contact can be used as a precondition for the release of the door
locking device.
The K1NO contact is closed if the internal mains contact is on. This
contact can be used as a precondition for the release of the drive enable
signal.
The UD contact acknowledges that the power supply system of the DKR
is working properly.
It opens in the event of the following disturbances:
•
DC bus voltage < 400 V
•
power contactor is open
Can be used:
•
as a precondition for the feed release and
•
for
diagnoses

If you pick off voltages at terminal connector X8, use
short, shielded leads and do not overload the
outputs.
