Serial comms
The following table shows trips that can be initiated that are related to the drive encoder feedback and whether they can be enabled and disabled by
Pr 3.40 .
1. If the terminations are not enabled on the A, B or Z inputs the wire break system will not operate (5 V or 8 V only). (Note that as default the Z
input terminations are disabled to disable wire break detection on this input.)
Wire-break detection
It may be important to detect a break in the connections between the drive and the position feedback device. This feature is provided for most
There is an overload or short circuit on the drive encoder terminals.
Power supply short circuit or overload on option encoder supply
There is an overload or short circuit on the option encoder power supply.
Both the above trips can over ride trip Enc2 so if there is a wire break trip and then a power supply trip the drive will store both trips in the trip log. Both
the above trips turn the terminal encoder supply off.
