Wiring Overview
Overview of 17S
Wiring
Connections The following diagram shows the wiring connections for the 17S drive.
Note: The connectors described above appear in many wiring diagrams throughout
the remainder of this document and are identified in those diagrams by their
alphanumeric designations only (for example, X4); the term
connector is excluded.
CAUTION:
Do not connect a Modbus serial port to the X6 connector!
Pin1 carries +8 Vdc which would be shorted out by a Modbus cable.
Instead, use a standard 3-core null-modem cable (not a null-modem link cable) with only
pins 2, 3 and 5 wired.
Failure to observe this precaution can result in equipment damage.
