5.4.8 Parallel Connection of Motors
The frequency converter can control several parallel-
connected motors. The total current consumption of the
motors must not exceed the rated output current I
the frequency converter.
When motors are connected in parallel, 1-29 Automatic
Motor Adaptation (AMA) cannot be used.
Small motors have relatively high ohmic resistance in the
stator, which can cause problems at start and low RPM.
The electronic thermal relay (ETR) of the frequency
converter cannot be used as motor protection for the
individual motor of systems with parallel-connected
motors. Provide further motor protection by e.g.
thermistors in each motor or individual thermal relays.
(Circuit breakers are not suitable as protection).
