Setting parameters for parallel operation
Parallel operation selection (Pr.1001)
Pr. Name
1001 Parallel operation
E390 selection
• To operate two converter units in parallel, set "200", and "1" or "2" in Pr.1001 Parallel operation selection of the master
and slave converter units respectively. (Setting either slave 1 or 2 will perform the operation.)
• To operate three converter units in parallel, set "300", "1", and "2" in Pr.1001 of the master, slave 1, and slave 2 converter
units respectively.
• Set "100 (initial value)" in Pr.1001 to enable operation using just one converter unit in the event of an emergency.
NOTE
• The setting of Pr.1001 will be applied after next power ON or converter unit reset.
• When the operation panel is installed to the converter units, the first monitor screen shows SLV.1 (parallel operation slave 1)
on the slave 1 converter unit (Pr.1001 = "1") and SLV.2 (parallel operation slave 2) on the slave 2 converter unit (Pr.1001 =
"2").
CAUTION
 Be sure to set Pr.1001 correctly. Operation with incorrect settings may damage the converter units.
Precautions when setting parameters for parallel operation
• Always set Pr.1001 of the master and reset the converter unit after setting Pr.1001 of the slave and resetting the converter
unit. If the parameter is set in the reverse order, the communication between the master and the slave may not be
performed correctly.
• Before the parallel operation, set the same values between the master and the slave in Pr.30, Pr.57, Pr.261, and Pr.598. If
the settings are not correct, parallel operation will not work correctly.
Resetting the converter during the parallel operation
• When the RES signal of the master remains ON, the master keeps attempting to perform the converter reset. However, the
slave performs the converter reset only once and does not keep attempting to perform the reset.
• For the converter reset, reset the master converter unit. The slave converter unit will be reset simultaneously.
