5. Interface descriptions

5.1. Signal voltages

The signal voltages can be tapped off of terminal strip X10. These terminals

are for measuring and test purposes. If these voltages are used out of the KDV,

then make sure that no interference voltages are coupled in (use short,

shielded cables).

Do not exceed the load capacity of the signal voltage outputs to ensure proper

operation of the drives! The ±15 V

are short-circuit-proof. The +24V

are

protected by fuse F2.

Operating no power to fault in the KDV 2.3 ready

status: the electronics or in the drive

Output open open closed

The Bb1 contact of the KDV 2.3 has a superordinate significance.

The E-stop chain of the drive system is tied into the Bb1 contact.

Only when it is closed may threephase AC power be applied!

The Bb1 contact closes when power for the electronics is applied to X10 and

there is no fault.

The Bb1 contact opens for the following faults:

• tachometer fault

• overtemperature in the drive modules

• drive module bridge fuses

• a fault in the ± 15V

/ +24V

signal voltages

• an open wire-ribbon connection or missing termination connector

• the heatsink temperature of the KDV 2.3 is too high

• ground short in drive system

• bleeder overload
