hi.
i have a AB PLC5 communicating to a Control Techniques Unidrive SP via MODBUS. the Unidrive is connected to an absolute encoder via SSI.
the encoder cable got ripped apart, blowing fuses. I had spare VFD, Encoder, & Cable on site in case this happened. the customer decided to try and fix it themselves, to no avail.
i cant get communitation/ feedback from either the old, or new encoder via a laptop (ive done this a few times before, i know what im doing) . turns out (from their reports) the "new" cable had an intermittent short between the 24VDC and CLOCK-. could this wreck the encoder completely?
