Note 2) Indicates the total effective value including the higher harmonics. Note 3) Indicates the case for the standard 4-pole squirrel cage motor. Note 4) When 40°C is exceeded, derate the output current by 2% for each 1°C.
  • Page 176 Appendix Note 6) This inverter is subject to the EC Low Voltage Directives. The rated input voltage will be 380 to 415V to comply to the EC Low Voltage Directives. Note 7) An output voltage exceeding the input voltage cannot be attained. Note 8) When using the speed sensor-less vector control, the vector control with speed sensor, or the PM motor control, select the applicable motor from the max.
