The figure below shows the motor operating as a sequence by FILO. The motor turns on
from the starting auxiliary motor (Starting Aux) by order, and turns off depending on the rise
of PID feedback. At this point, the interlock occurs at auxiliary motor #2 by multi-function
input, the auxiliary motor turns off. The output frequency falls to the frequency set at AP1-71,
and rises again. Then, the interlock occurs at auxiliary motor #1. The auxiliary motor stops
and falls to the frequency set at AP1-71, and then rises again. Interlock #2 should be
released first, then release interlock #1 to let the auxiliary motor operate (When interlocks
are released, they will have the lowest priority of the operating motors). If the auxiliary motor
turns off by a rise of Feedback, the auxiliary motors turns off in order from 1 to 5, because
auxiliary motor #1 turned on last. The interlocked auxiliary motor will have the lowest priority.
IN-65–71 PxDefine: Select the terminal from the input terminal function group (IN-65–71) and
set Interlock 1-5 respectively with the correct motor order. When auto change mode selection
(AP1–55) is set to ‗0 (None)‘ or ‗1 (Aux)‘, and if 5 motors are operated, including the main motor,
the interlock numbers 1,2,3,4,5 refer to the montors connected to Relay 1,2,3,4,5 (If interlock
numbers 1,2,3,4,5 are connected to Relay 1,2,3,4,5 at the inverter output terminal).
However, if auto change mode selection (AP1-55) is set to ‗2 (Main)‘, and the main and auxiliary
motors are connected to the inverter output terminal Relay 1,2,3,4, Interlock 1,2,3,4 are the
monitors connected to Relay 1,2,3,4.
