protection not provided
Motor output current is detected by the inverter built-in
electronic thermal overload function, and inverter
exclusive-use motors or standard motors are prevented
from overloading . (It is not necessary to mount the
thermal overload relay externally . However, to
connect several motors to one inverter, a thermal
overload relay must be inserted for each motor. It is
necessary to reduce carrier frequency according to the
wiring distance between the inverter and motor when
thermal overload relays are inserted. For details, refer
to the precautions on wiring described on page 29 .)
