Damage or injury occurrence by missing
acquisition of information related to risk
When the motor wiring distance exceeds
20m or more, try to shorten the wiring.
Use LCR filter or output AC reactor.
Use motor according to the inverter
voltage class.
Confirm the inverter power supply
voltage, feeding method and capacity.
Verify the motor output line that not
being in open phase.
Set adequate value for related function
parameter of motor electronic thermal
level [bC-01] to [bC125].
Set adequate value for base frequency,
motor rated current, control mode,
motor constant, load rating, direct
current output related parameters.
(representative parameter)
Motor related parameter:
IM: [Hb102] to [Hb118]
SM(PMM): [Hd102] to [Hd118]
Control mode: [AA121]
Load rating: [Ub-03]
DC braking: [AF101] to [AF109]
If automatic restart after motor stop is set
by a function, make sure to clearly
describe that in the system.
Confirm that system is structured for fail
safe considering a risk assessment.
Obtain the latest version of user's guide
to make those information available.
Inform users appropriately.
For using [SET] function of input terminal, similarly, set the
