(Note 1) Protective system bases on JME1030.
(Note 2) Applicable motor indicates HITACHI three-phase motor. When you use other motor, set so that the motor current doesn’t exceed the rated current of the inverter.
(Note 3) Output voltage will reduce when the power voltage is reduced. (Except when AVR function is selected.)
(Note 4) When you operate motor over 50/60Hz, inquire about the allowable max.revolution time of motor etc. from motor manufacturer.
(Note 5) Braking resistance isn’t installed in the inverter. When the inverter requires a high regenerative torque, use optional braking resistance and regenerative braking unit.
(Note 6) Protective temperature is temperature during transportation.
(Note 7) This bases on the test methods of JIS C0911(1984).
(Note 8) When the inverter is used in a place with dust, we recommend the optional varnish coating specification. Before it is required.
(Note 9) When you use cable for remote operation, please remove connector. Please refer to 1.3 Appearance.
(Note 10) When using at 50ºC of ambient air temperature, the rated output current will be reduced. (P.4-18)
(Note ) Insulation distance is based on UL, CE standard.
