Setting the drive parameters
„
Remove power from the drive and wait for the charge lamp to be completely extinguished. Wait at least five additional minutes for the drive to be
completely discharged. Measure the DC BUS voltage and verify that it is at a safe level.
„ Reinstall the operator keypad and all drive covers. Apply power to the drive.
„ Set parameter A1-01 to 2, Advanced.
„ Set parameters b1-01 and b1-02 to their appropriate values. Refer to the table below for available b1-01 and b1-02 values. Reference Selection
and Operation Method Selection can have different values depending on the application. To control both frequency and run/stop over the network,
set both b1-01 and b1-02 to 2, Serial Communications.
„ Set parameter H5-01 to 1F (31)
„ Set parameter H5-02 to 3, 9600 baud
„ Set parameter H5-03 to 0, No Parity
„ Set parameter H5-06 to 5, 5ms transmission wait
„ Set parameter H5-07 to 0, Disabled
„ Set parameter H5-08 to 0, MODBUS
„ Parameters H5-04 (Stopping Method at Communications Fault), H5-05 (Serial Fault Detection) and H5-09 (CE Detect Time) should be set according
to the desired drive performance during a communications timeout or failure.
„ After all drive parameters have been set, power cycle the drive. Communications parameters will not take affect until power has been removed from
the drive until the charge lamp has been extinguished and restored.
„ For E7L or E7B Bypass-Panel applications, refer to the parameter table and electrical schematic accompanying the unit for parameter and DIP-
switch settings.
