12
(a)
Installation Wiring - DANGER
Motor insulation damage due to surge
caused by long distance motor wiring.
When the motor wiring distance exceeds
20m or more, try to shorten the wiring.
Use LCR filter or output AC reactor.
□
12
(b)
Installation Wiring - DANGER
Motor damage due to insulation failure
caused by motor voltage unmatched. Use motor according to the inverter
voltage class.
□
12
(c)
Installation Wiring - DANGER
Motor damage due to unstable power
supply, caused by power supply
unbalance, low voltage or excessive
voltage drop.
Confirm the inverter power supply
voltage, feeding method and capacity.

- DANGER
Motor damage due to continue ran in
open phase on motor output line. Verify the motor output line that not
being in open phase.

Maintenance
Setting - DANGER
Motor damage due high current on motor
caused by inadequate parameter setting.
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]
13 Use Operation (C) DANGER
The motor once stopped runs
automatically.
If automatic restart after motor stop is set
by a function, make sure to clearly
describe that in the system.
□
14 General General - DANGER
Damage or injury occurrence from a
hidden risk. Confirm that system is structured for fail
safe considering a risk assessment.
□
15 General General
