Serial Communications:
Terminals are provided for "full duplex" or "half duplex" connections to the Drive for RS422/RS485 serial communi-
cation.
For "half duplex" operation via Metasys N2 protocol (enabled with option J), APOGEE FLN protocol (enabled with
option U) or Modbus protocol (enabled with option V) field configuration of these terminals is required.
When no cost options J, U or V are ordered:
•
Jumpers are provided for field installation on terminals TB4-1 to TB4-3 and TB4-2 to TB4-4.
•
The E7 Drive is programmed to enable the appropriate protocol (parameter H5-08), baud rate (parameter
H5-02), RTS control (parameter H5-07) and error detection time (parameter H5-09).
Option L (LonWorks) does not require jumpers and (with the exception of H5-07) employs the same parameter set-
tings as Modbus.
Parameter (Function)
H5-02 (Baud Rate)
H5-07 (RTS Control)
H5-08 (Protocol)
H5-09 (Error Time)
For co-ordination with other E7 Technical Manuals, the table below provides the equivalency between E7B_ _ _T or
E7B_ _ _Y Control PCB A2 terminal designations and E7 Drive terminal designations used in TM.E7.01, TM.E7.02,
TM.E7.21, TM.E7.22 and TM.E7B.01.
