3.16. Electronics supply and signal exchange
connections
Terminal connection X1 has two functions:
• voltage source to the drive electronics and
• signal exchange between supply and drive module(s)
The wire ribbon cable on the TVD 1.3 side has 16 pins. It is included in the
electrical connecting accessories of the drive module.
Fig. 3.14: Transition from 16-pin bus connector to 12-pin bus connector
The wire ribbon connection is completed with a terminating plug for
verifying the wiring. Without it, the high voltage section cannot be powered
up. The TVD 1.3 can also be installed in the middle of the drive package.
In this case, it suffices if one end of the wire ribbon cable is terminated.
The terminating plug is part of the connecting accessories of the supply
module.
