3.17. Signal and Diagnostics Outputs
Zero potential contact - Connector X8/7-X8/8
Maximum load: DC 24V/1A (do not attach higher voltages!)
Operating state Relay Error ready
power off
Output Bb open open closed
The Bb contact signals that the drive is ready for powering up.
Internal interlocking devices will not permit the mains contactor in the DDC to
be turned on until it is closed. The mains contactor is deactivated and the Bb
contact opened with an error. Once the Bb contact opens, there can be no
controlled deceleration of the drives. It can, therefore, be used to trip the
dynamic brake.

Output UD open open closed
The UD contact is closed if the DC bus voltage is greater than 200 V and the
mains contactor is turned on.
The UD contact can be used as a prerequisite for releasing the feed function.
Zero potential contact - Connector X8/11-X8/12
Maximum load: DC 24V/1A
AC 250V/1A
The bleeder warning contact opens, if continuous regenerated power is
greater than 75% of continuous bleeder power. Should the bleeder load
continue to climb to thermal overload, then the power supply to the DDC is
discontinued.
